Abstract
Description
本发明的背景Background of the Invention
草甘膦或N-膦酰甲基甘氨酸,是一个熟知的芽后广谱性除草剂。典型的市售剂型含有大约41%的草甘膦异丙胺盐和12%(重量计)乙氧基化牛脂胺表面活性剂。草甘膦是一种相对不溶性酸,因此被加工成盐,例如异丙胺盐,钠盐或铵盐的形式来施用。Glyphosate, or N-phosphonomethylglycine, is a well-known post-emergence broad-spectrum herbicide. A typical commercial formulation contains about 41% glyphosate isopropylamine salt and 12% by weight ethoxylated tallow amine surfactant. Glyphosate is a relatively insoluble acid and is therefore processed and applied as salts such as isopropylamine, sodium or ammonium.
通常将表面活性剂掺入剂型中以改进草甘膦的活性。但是,“表面活性剂”一词的含义是不明确的,因为由制造厂家提供的不一定是一种单个化合物,而可能是一种混合物。例如,关于乙氧基化的表面活性剂,乙氧基化程度可能是,和典型的是一个统计混合物。文献中介绍在草甘膦组合物中采用表面活性剂,特别是杂草科学Vol.25,pp.275-287(1977)说明在草甘膦剂型中必须包含有一种表面活性剂。常规的草甘膦剂型采用例如硅氧烷的表面活性剂,可以提高草甘膦剂型的耐雨特性。可是,这种表面活性剂混入该剂型以后成本增加,以及它的水解不稳定性,又阻碍了这种剂型的商品化。含有表面活性剂的其它剂型在US5,362,705,5,180,414和5,118,338中有介绍。Surfactants are often incorporated into dosage forms to improve the activity of glyphosate. However, the meaning of the term "surfactant" is ambiguous, since it is not necessarily a single compound but a mixture that is supplied by the manufacturer. For example, with respect to ethoxylated surfactants, the degree of ethoxylation may be, and typically is, a statistical mixture. The literature introduces the use of surfactants in glyphosate compositions, especially Weed Science Vol. 25, pp. 275-287 (1977), which shows that a surfactant must be included in glyphosate formulations. Conventional glyphosate formulations use surfactants such as siloxane, which can improve the rain resistance of glyphosate formulations. However, the increased cost of this surfactant after incorporation into the dosage form, and its hydrolytic instability hinder the commercialization of this dosage form. Other dosage forms containing surfactants are described in US 5,362,705, 5,180,414 and 5,118,338.
此外,近来围绕化学农药的使用和农药残留可能污染食品和地下水等问题的环境关注,希望从根本上减少有效农药的用量。In addition, recent environmental concerns surrounding the use of chemical pesticides and the potential for pesticide residues to contaminate food and groundwater have led to the desire to radically reduce the amount of effective pesticides used.
所以,本发明的目的是在不使用硅氧烷表面活性剂的情况下,改进农药剂型的耐雨特性。It was therefore an object of the present invention to improve the rainfastness properties of pesticide formulations without the use of silicone surfactants.
本发明的另一个目的是通过环境支持的方法提高这些剂型的效果。Another object of the present invention is to enhance the efficacy of these dosage forms by means of environmental support.
本发明的概要Summary of the invention

More particularly, the present invention relates to a pesticide composition in which the pesticide is combined with a hydrophilic isocyanate-terminated prepolymer to significantly increase the efficacy of the pesticide. This pesticide composition comprises surfactant, pesticide and hydrated polymer or hydrophilic prepolymer composed of isocyanate-terminated prepolymer, which shows higher drug efficacy than conventional pesticide formulations, wherein The prepolymer consists essentially of ethylene oxide, propylene oxide or butylene oxide units or combinations thereof.

The liquid compositions of the present invention can be prepared by simple mixing of the individual components. An effective order of addition can be employed, if desired, so as to endcap with free isocyanato groups in the hydrophilic prepolymer. In the literature, hydrophilic prepolymers comprising isocyanate-terminated prepolymers consisting essentially of ethylene oxide, propylene oxide or butylene oxide units or combinations thereof, are hydratable or water-soluble sexual.

In one embodiment, the water-soluble prepolymer can be covalently bonded to an amino group present in the pesticide (such as glyphosate), or to an alcohol group present in the pesticide (such as dicofol (commercially available). trade name Kelthane)). In another embodiment, the prepolymer can be reacted with water to form polyurethane and polyurea-urethane polymer glues prior to combination with the pesticide. In still further embodiments, the prepolymer can form a reaction product with the surfactant through covalent bonding between the isocyanato groups of the prepolymer and reactive groups on the surfactant.

在本发明中用作起始原料的预聚物提供水合的聚氨酯,聚脲-氨酯和聚脲聚合物胶。许多聚氨酯聚合物以前已经鉴定过。从各种预聚物制备的许多水凝胶聚合物已经制得,并获得广泛的应用。典型地,通过在水溶液中,在预聚物变成交链,形成三维的聚合物网而使溶液胶化成浓的形式的条件下,聚合亲水性单体来制备水凝胶。聚氨酯水凝胶是通过聚合异氰酸根封端的预聚物形成尿和尿烷键合来制备的。更特别的是,预聚物是从高分子量的、基本上或全部是由环氧乙烷、环氧丙烷或环氧丁烷单元,或其混合物组成的异氰酸酯封端的预聚物制得。优选的预聚物是由聚合单体单元(预聚物单元)衍生而来的。这些聚合物单元至少75%是分子量约100至约30,000,优选7000至30,000的氧乙烯基二醇或多醇,这些二醇或多醇的羟基基本上全部以聚异氰酸酯封端。适宜的多醇有三醇,例如甘油,三羟甲基丙烷,三羟甲基乙烷和三羟乙基胺。在本发明中采用的预聚物,通过选自二醇,三醇或多醇的醇与聚异氰酸酯在异氰酸根与羟基的比为大约1.8-2.2的条件下,反应制得,结果基本上全部羟基都以聚异氰酸根封端。芳族、脂族或环脂族的聚异氰酸酯可以使用。采用脂族的聚异氰酸酯允许有更大程度的处理和/或塑造性,因为脂肪异氰酸酯封端的预聚物一般需要20至90分钟才能成胶,变成水合的聚合物状态。芳基的聚异氰酸酯胶封端的预聚物更快些,大约30至60秒。脂肪的聚异氰酸酯也根据降低低毒性的观点来优选。适宜的双官能和多官能的异氰酸酯实例如下:2,4-甲苯双异氰酸酯,2,6-甲苯双异氰酸酯,市售的2,4-甲苯双异氰酸酯和2,6-甲苯双异氰酸酯的混合物,异佛尔酮双异氰酸酯,乙撑双异氰酸酯,亚乙基双异氰酸酯,丙撑-1,2-双异氰酸酯,环己撑-1,2-双异氰酸酯,环己撑-1,4-双异氰酸酯,间苯二撑双异氰酸酯,3,3″-双苯基-4,4″-二苯撑双异氰酸酯,1,6-六亚甲基双异氰酸酯,1,4-四亚甲基双异氰酸酯,1,10-十亚甲基双异氰酸酯,异丙苯-2,4-双异氰酸酯,1,5-萘双异氰酸酯,甲撑双环己基双异氰酸酯,1,4-环己撑双异氰酸酯,对-四甲基二甲苯双异氰酸酯,对苯撑双异氰酸酯,4-甲氧基-1,3-苯撑双异氰酸酯,4-氯-1,3-苯撑双异氰酸酯,4-溴-1,3-苯撑双异氰酸酯,4-乙氧基-1,3-苯撑双异氰酸酯,2,4-二甲基-1,3-苯撑双异氰酸酯,2,4-二甲基-1,3-苯撑双异氰酸酯,5,6-二甲基-1,3-苯撑双异氰酸酯,2,4-双异氰酸酯基二苯醚,4,4′-双异氰酸酯基二苯醚,联苯胺双异氰酸酯,4,6-二甲基-1,3-苯撑双异氰酸酯,9,10-蒽撑双异氰酸酯,4,4′-双异氰酸酯基双苄,3,3′-二甲基-4,4′-二异氰酸酯基二苯基甲烷,2,6-二甲基-4,4′-双异氰酸酯联苯,2,4-双异氰酸酯基均二苯代乙烯,3,3′-二甲氧基-4,4′-双异氰酸酯基联苯,1,4-蒽双异氰酸酯,2,5-芴双异氰酸酯,1,8-萘双异氰酸酯,2,6-双异氰酸酯基苯并呋喃,2,4,6-甲苯三异氰酸酯,P,P′,P″-三苯基甲烷三异氰酸酯,异佛尔酮双异氰酸酯的三官能团三聚物(异氰脲酸酯),六甲撑双异氰酸酯的三官能团缩二脲,六甲撑双异氰酸酯的三官能团三聚物(异氰脲酸酯),聚合的4,4′-二苯甲烷双异氰酸酯,二甲苯撑双异氰酸酯和间四甲基二甲苯撑双异氰酸酯。The prepolymers used as starting materials in the present invention provide hydrated polyurethane, polyurea-urethane and polyurea polymer glues. Many polyurethane polymers have been identified previously. Many hydrogel polymers prepared from various prepolymers have been prepared and found a wide range of applications. Typically, hydrogels are prepared by polymerizing hydrophilic monomers in aqueous solution under conditions under which the prepolymer becomes cross-linked, forming a three-dimensional polymer network that gels the solution into a concentrated form. Polyurethane hydrogels are prepared by polymerizing isocyanate-terminated prepolymers to form urea and urethane linkages. More particularly, the prepolymer is prepared from a high molecular weight isocyanate-terminated prepolymer consisting essentially or entirely of ethylene oxide, propylene oxide or butylene oxide units, or mixtures thereof. Preferred prepolymers are derived from polymerized monomer units (prepolymer units). At least 75% of these polymer units are oxyethylene diols or polyols having a molecular weight of from about 100 to about 30,000, preferably 7000 to 30,000, substantially all of which are hydroxyl terminated with polyisocyanates. Suitable polyols are triols such as glycerol, trimethylolpropane, trimethylolethane and triethylolamine. The prepolymers used in the present invention are prepared by reacting alcohols selected from diols, triols or polyols with polyisocyanates at an isocyanate-to-hydroxyl ratio of about 1.8-2.2, resulting in essentially All hydroxyl groups are terminated with polyisocyanate. Aromatic, aliphatic or cycloaliphatic polyisocyanates can be used. The use of aliphatic polyisocyanates allows for a greater degree of handling and/or moldability, since aliphatic isocyanate-terminated prepolymers generally require 20 to 90 minutes to gel and become a hydrated polymer state. Aryl polyisocyanate gum terminated prepolymers are faster, about 30 to 60 seconds. Aliphatic polyisocyanate is also preferable from the viewpoint of reducing toxicity. Examples of suitable difunctional and polyfunctional isocyanates are as follows: 2,4-toluene diisocyanate, 2,6-toluene diisocyanate, commercially available mixtures of 2,4-toluene diisocyanate and 2,6-toluene diisocyanate, iso Phorne diisocyanate, ethylene diisocyanate, ethylene diisocyanate, propylene-1,2-diisocyanate, cyclohexylene-1,2-diisocyanate, cyclohexylene-1,4-diisocyanate, meta phenylene diisocyanate, 3,3″-bisphenyl-4,4″-diphenylene diisocyanate, 1,6-hexamethylene diisocyanate, 1,4-tetramethylene diisocyanate, 1, 10-decamethylene diisocyanate, cumene-2,4-diisocyanate, 1,5-naphthalene diisocyanate, methylene biscyclohexyl diisocyanate, 1,4-cyclohexylene diisocyanate, p-tetramethyl Xylene diisocyanate, p-phenylene diisocyanate, 4-methoxy-1,3-phenylene diisocyanate, 4-chloro-1,3-phenylene diisocyanate, 4-bromo-1,3-phenylene diisocyanate Isocyanate, 4-ethoxy-1,3-phenylene diisocyanate, 2,4-dimethyl-1,3-phenylene diisocyanate, 2,4-dimethyl-1,3-phenylene diisocyanate , 5,6-dimethyl-1,3-phenylene diisocyanate, 2,4-diisocyanate diphenyl ether, 4,4'-diisocyanate diphenyl ether, benzidine diisocyanate, 4,6- Dimethyl-1,3-phenylene diisocyanate, 9,10-anthracene diisocyanate, 4,4'-diisocyanatobisbenzyl, 3,3'-dimethyl-4,4'-diisocyanate Diphenylmethane, 2,6-dimethyl-4,4'-diisocyanate biphenyl, 2,4-diisocyanato-stilbene, 3,3'-dimethoxy-4,4' -Diisocyanatobiphenyl, 1,4-anthracene diisocyanate, 2,5-fluorene diisocyanate, 1,8-naphthalene diisocyanate, 2,6-diisocyanatobenzofuran, 2,4,6-toluene triisocyanate Isocyanates, P, P′, P″-triphenylmethane triisocyanate, trifunctional trimer of isophorone diisocyanate (isocyanurate), trifunctional biuret of hexamethylene diisocyanate, hexamethylene Trifunctional trimers of diisocyanates (isocyanurates), polymerized 4,4'-diphenylmethane diisocyanate, xylylene diisocyanate and m-tetramethylxylylene diisocyanate.
采用化学计算量的反应剂,以聚异氰酸根封端二醇或多醇,形成本发明所用的预聚物。异氰酸根与羟基的比例应在0.01至10之间,优选0.1至3,最优选0.2至2.2。更高的比例可以采用,但是并不优选,因为可能导致与存在于最终产品中的过量单体相结合的问题。封端反应可以任何方便的方法或程序进行,例如在大约20-150℃,在干燥氮气存在下,大约2小时至14天,优选在无催化剂的条件下进行。优选的温度是大约60至100℃。当异氰酸酯浓度约为理论值时为反应终点。The prepolymers used in this invention are formed by capping diols or polyols with polyisocyanates using stoichiometric amounts of reactants. The ratio of isocyanate to hydroxyl should be between 0.01 and 10, preferably 0.1 to 3, most preferably 0.2 to 2.2. Higher ratios can be used, but are not preferred as they may cause binding problems with excess monomer present in the final product. The capping reaction may be carried out by any convenient method or procedure, for example at about 20-150°C in the presence of dry nitrogen for about 2 hours to 14 days, preferably in the absence of a catalyst. A preferred temperature is about 60 to 100°C. When the isocyanate concentration is about the theoretical value, it is the end of the reaction.
优选的预聚物包括甲苯双异氰酸酯-聚乙烯乙二醇-三羟甲基丙烷,甲撑双异氰酸酯-甲撑双异氰酸酯均聚物-聚合的甲撑双异氰酸酯-聚乙二醇,甲苯双异氰酸酯和环氧乙烷与环氧丙烷和三羟甲基丙烷的聚合物,异佛尔酮双异氰酸酯和环氧乙烷-环氧丙烷-三羟甲基丙烷的聚合物,甲苯双异氰酸酯聚乙二醇三乳酸酯,和终端带有甲苯的双异氰酸酯的聚乙二醇。这种预聚物可从Hampshire化学公司得到,商品名HYPOL,还有HYPOL PreMA,HYPOL 2000,HYPOL 3000,HYPOL 4000,HYPOL 5000和可生物降解的HYPOL。Preferred prepolymers include toluene diisocyanate-polyethylene glycol-trimethylolpropane, methylene diisocyanate-methylene diisocyanate homopolymer-polymerized methylene diisocyanate-polyethylene glycol, toluene diisocyanate Polymers of and ethylene oxide with propylene oxide and trimethylolpropane, polymers of isophorone diisocyanate and ethylene oxide-propylene oxide-trimethylolpropane, toluene diisocyanate polyethylene glycol alcohol trilactate, and polyethylene glycol with toluene-terminated diisocyanate. Such prepolymers are available from Hampshire Chemical Company under the tradename HYPOL, as well as HYPOL PreMA, HYPOL 2000, HYPOL 3000, HYPOL 4000, HYPOL 5000 and biodegradable HYPOL.
农药与预聚物的典型比例大约0.001至10。A typical ratio of pesticide to prepolymer is about 0.001 to 10.
例如在草甘膦的情况下,可以用任何一种适当的碱,包括碱金属,碱土金属和铵氢氧化物与烷基胺中和草甘膦酸而生成具有除草活性的草甘膦衍生物。优选的中和得到的草甘膦盐包括N-膦酰甲基甘氨酸的单(三甲胺)盐,N-膦酰甲基甘氨酸的单(二乙撑三胺)盐,N-膦酰甲基甘氨酸的单异丙胺盐,N-膦酰甲基甘氨酸的单正丙胺盐,N-膦酰甲基甘氨酸的单牛脂胺盐,N-膦酰甲基甘氨酸的单钠盐和N-膦酰甲基甘氨酸的单钾盐。熟悉这些技术的人很容易理解通过增加相应的碱量也可以制备N-膦酰甲基甘氨酸的相应二盐和三盐。For example in the case of glyphosate, glyphosate acid can be neutralized with any suitable base including alkali metal, alkaline earth metal and ammonium hydroxides with alkylamines to yield herbicidally active glyphosate derivatives . Preferred neutralized glyphosate salts include mono(trimethylamine) salt of N-phosphonomethylglycine, mono(diethylenetriamine) salt of N-phosphonomethylglycine, N-phosphonomethylglycine Monoisopropylamine salt of glycine, mono-n-propylamine salt of N-phosphonomethylglycine, monotallowamine salt of N-phosphonomethylglycine, monosodium salt of N-phosphonomethylglycine and N-phosphonomethylglycine monopotassium salt of glycine. Those skilled in the art will readily understand that the corresponding di- and tri-salts of N-phosphonomethylglycine can also be prepared by increasing the amount of the corresponding base.
在本发明的第一个实施方案中,预聚物可以作为与水的反应产物混入溶液中。所用的预聚物的量应该少到足以避免立即生成胶体。一般说少于20%(重量计)是适宜的,更优选的是大约2~10%(重量计),最优选的是大约3~7%(重量计)。如果需要比较大量的预聚物,可以加入伯烷基胺或仲烷基胺以帮助防止胶体形成。反应优选在刚刚高于水的冰点至室温下进行。比较高的温度可以采用,但是会增加生成胶体的比例。在预聚物/水的反应完成后加入农药。所用农药的量取决于在最后的剂型中所需要的量,一般约在0.1%至80%(重量计)。得到透明的、稳定的溶液或悬浮液。在草甘膦的情况下,当前市售的剂型约含有36%草甘膦酸(41%为异丙胺盐)。加入草甘膦酸会导致形成一种白色浆液。再用任一种适宜的碱,优选氢氧化物,例如氢氧化钠、钾或铵,最优选是异丙胺来中和浆液。最好加入足够的碱以形成单盐,可是再加入碱时会生成二盐和三盐。In a first embodiment of the invention, the prepolymer can be mixed into solution as a reaction product with water. The amount of prepolymer used should be small enough to avoid immediate gel formation. Generally less than 20% by weight is suitable, more preferably about 2-10% by weight, most preferably about 3-7% by weight. If larger amounts of prepolymer are desired, primary or secondary alkylamines can be added to help prevent gel formation. The reaction is preferably carried out at temperatures from just above the freezing point of water to room temperature. Higher temperatures can be used, but will increase the proportion of colloids formed. The pesticide is added after the prepolymer/water reaction is complete. The amount of pesticide used will depend on the amount desired in the final dosage form and will generally range from about 0.1% to about 80% by weight. A clear, stable solution or suspension is obtained. In the case of glyphosate, the current marketed dosage form contains approximately 36% glyphosate acid (41% isopropylamine salt). Addition of glyphosate acid resulted in the formation of a white slurry. The slurry is then neutralized with any suitable base, preferably a hydroxide such as sodium, potassium or ammonium, most preferably isopropylamine. It is best to add enough base to form a monosalt, but when more base is added, di- and triple-salts are formed.
可在预聚物与水反应后的任何时候加入表面活性剂,也就是说,可在加农药之前立即加入,中和之前立即加入,或中和之后加入。优选的表面活性剂加入量约为农药的0.1%至20%(重量/重量),实际的量取决于所用表面活性剂的特性。水-蒸发,就可得到强弹性的薄膜。这些薄膜是可水合的水溶性薄膜,它可在该剂型喷雾到基质上之后形成。这种可水合的薄膜是很需要的,因为它们可以减少或防止农药从被喷雾的基质表面(例如植物的叶面)上洗掉。这些可水合性薄膜也可大大提高剂型的耐雨特性。The surfactant can be added at any time after the prepolymer has reacted with water, that is, it can be added immediately before the pesticide is added, immediately before neutralization, or after neutralization. The preferred amount of surfactant added is about 0.1% to 20% (w/w) of the pesticide, the actual amount depending on the nature of the surfactant used. When the water evaporates, a strong elastic film can be obtained. These films are hydratable, water soluble films which can be formed after the dosage form has been sprayed onto the substrate. Such hydratable films are highly desirable because they reduce or prevent wash-off of pesticides from sprayed substrate surfaces, such as plant foliage. These hydratable films can also greatly improve the rain resistance properties of the dosage form.
在本发明的第二实施方案中,将应用具有能够与预聚物形成共价键的反应性基团的农药,将该预聚物作为与农药共价结合的反应产物掺入剂型中。特别是在草甘膦的情况下,将草甘膦酸直接加到预聚物中,并与存在于预聚物中的游离异氰酸根基反应而封端。取决于所用草甘膦的是,可以是部分或全部异氰酸根基封端。所得到的反应产物,如在第一实施方案中所述,以适当的碱中和。在中和前或中和后加入表面活性剂。所用的各组分的量与上述第一实施方案的量相似。In a second embodiment of the invention, pesticides having reactive groups capable of forming a covalent bond with a prepolymer incorporated into the dosage form as a reaction product covalently bound to the pesticide will be used. In the case of glyphosate in particular, glyphosate acid is added directly to the prepolymer and reacts with free isocyanato groups present in the prepolymer to cap. Depending on the glyphosate used, it may be partially or fully isocyanato-blocked. The resulting reaction product, as described in the first embodiment, is neutralized with a suitable base. Surfactant is added before or after neutralization. The amounts of the components used are similar to those of the first embodiment described above.
在本发明的第三个实施方案中,加入亲水性异氰酸酯封端的预聚物,这是通过聚合物的异氰酸根基(-NCO)和表面活性剂上的反应性基团,例如伯胺或仲胺基(-NH2,-NH),巯基(-SH),羟基(-OH)和羧基(-COOH)之间的共价结合,与表面活性剂的反应产物。与第二实施方案一样,取决于所用反应剂的量,在预聚物中可以部分或全部以异氰酸根基封端。优选的表面活性剂是乙氧基化的烷基胺,包括烷基或烷基芳基乙氧基化物,包括聚乙二醇,二甘醇和乙二醇。然后加农药。在某些情况下,也可用适当的阳离子或阴离子表面活性剂。所用的各组分的量与上述第一实施方案的量相近。In a third embodiment of the present invention, a hydrophilic isocyanate-terminated prepolymer is added via the isocyanato group (-NCO) of the polymer and reactive groups on the surfactant, such as a primary amine Or the covalent bond between secondary amino group (-NH 2 , -NH), mercapto group (-SH), hydroxyl group (-OH) and carboxyl group (-COOH), and the reaction product of surfactant. As in the second embodiment, depending on the amount of reactants used, it is possible to partially or completely end-block with isocyanato groups in the prepolymer. Preferred surfactants are ethoxylated alkylamines, including alkyl or alkylaryl ethoxylates, including polyethylene glycol, diethylene glycol and ethylene glycol. Then add pesticides. In some cases, suitable cationic or anionic surfactants may also be used. The amounts of the components used are similar to those of the first embodiment described above.
本发明的剂型优选喷雾施用于植物的地上部分。有效成分的浓度应该达到农药的有效量,它取决于特定的农药和害物与所需要的效果。The formulations according to the invention are preferably applied by spray to the above-ground parts of the plants. The concentration of the active ingredient should be such that the pesticide effective amount depends on the particular pesticide and pest and the desired effect.

The sample is then weighed and the weight noted. A colorless to white residue was visible on the bottom of all vials. An additional 10 ml of water was added to each vial and left to stand for at least 1 hour. The liquid portion of the sample was then removed from the vial and placed into a pre-weighed aluminum weighing pan. The weighing pan and vial were then placed in an oven at 55°C and left overnight in the oven to allow the water to evaporate. Weigh each sample again and record the new weight. Then calculate the change from the original weight. These data show that as the reaction progressed, the percentage of the stock solution dried in the vial to the stock solution dissolved in 10 ml of water decreased. Samples collected at the end of the reaction formed clear, stable gels that were hydrophilic and only partially soluble in water.
