The present invention relates to diethylmethylammonium nitrile represented by the formula (1), wherein A is an anion.

Said compounds are suitable as bleach activators in detergents and detergents.

Description

  The present invention relates to a geruchsneutrale short chain ammonium nitrile, its granules and a method of using them to increase the bleaching action of peroxygen compounds in the bleaching of colored stains on textile materials and hard surfaces, and It relates to detergents and detergents containing nitrile as a bleach activator.

  Inorganic peroxygen compounds, especially hydrogen peroxide, and solid peroxygen compounds that dissolve in water while releasing hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have traditionally been disinfected and used as oxidants. Used for bleaching purposes. The oxidizing action of these substances depends strongly on the temperature in the dilute solution, for example when using hydrogen peroxide or perborate in an alkaline bleaching solution, the fouling is only possible at temperatures above about 80 ° C. A sufficiently fast bleaching of the fiber material is achieved.

  Addition of bleaching peroxyacid precursors, known as bleach activators, where the low-temperature oxidizing action of peroxide bleaches such as perborate, percarbonate, persilicate and perphosphate It is known that Many materials are conventionally known as bleach activators. They are usually reactive organic compounds having an O-acyl group or an N-acyl group, which together with the hydrogen peroxide source form the corresponding peroxyacid in an alkaline solution. Representative examples of bleach activators include, for example, N, N, N ′, N′-tetraacetylethylenediamine (TAED), glucose pentaacetate (GPA), xylose tetraacetate (TAX), sodium-4-benzoyloxy Benzenesulfonate (SBOBS), sodium trimethylhexanoyloxy-benzenesulfonate (STHOBS), tetraacetylglycoluril (TAGU), 1-phenyl-3-acetylhydantoin (PAH), sodium-nonanoyloxy-benzenesulfonate (NOBS) and sodium- Isononanoyloxy-benzenesulfonate (ISONOBS). Of interest is a group of cationic compounds that contain quaternary ammonium groups, since these are highly effective bleach activators.

  By adding these activators to aqueous peroxide solutions, perhydrolysis occurs while releasing organic peracids. This enhances the bleaching action of the solution to such an extent that even at temperatures of 40-60 ° C., the same effect is obtained as when the peroxide solution is used alone at 95 ° C.

  The main disadvantage of the aforementioned bleach activators is that they typically leave leaving groups (eg phenol sulfonates) that are of no value in the bleaching process after perhydrolysis.

  From an environmental point of view, bleach activators in which highly reactive peracids are released in the perhydrolysis stage and no leaving groups are released are of interest. This is achieved, for example, by a cyano group. This probably forms peroxyimidic acid which then acts as a bleaching agent in perhydrolysis.

  An example of this is the following component:

An ammonium nitrile characterized by

This type of compound and methods of using them as activators in bleaching agents are described in Patent Document 1, Patent Document 2 and Patent Document 3. An ammonium nitrile in which ^{two of the} R ¹ , R ² or R ³ groups are long-chain alkyl groups is described in Patent Document 4.

  However, low molecular weight ammonium nitriles with a total of 12 or fewer carbon atoms are particularly interesting because they have excellent water solubility, high reactivity, and at the same time significant weight efficiency (gewichtseffektiv) . This plays a particular role when volumeneffektiven detergents are used in small quantities. Therefore, production of such a compound has been attempted so far. In numerous patent applications, the formula:

Wherein X ⁻ is an anion such as chloride ion, sulfate ion, hydrogen sulfate ion, methyl sulfonate ion, ethane sulfonate ion, toluene sulfonate ion, benzene sulfonate ion or cumene sulfonate ion. A method of using certain trimethylammonium acetonitrile is described. Examples relating to the synthesis, granulation and use of these trimethylammonium acetonitriles are described in Patent Document 5, Patent Document 6, Patent Document 7 or Patent Document 8.

However, a significant disadvantage of all trimethylammonium acetonitriles is that they release trace amounts of trimethylamine under alkaline conditions, whether in a cleaning solution or stored for a long time in an alkaline detergent, and thus have a savory smell. It can not be used for home use. Therefore, for example, attempts have been made to produce odorless trimethylammonium acetonitrile by anion exchange or deodorization as described in Patent Document 9.
European Patent Application Publication No. 303520 European Patent Application No. 458396 European Patent Application Publication No. 464880 International Publication No. 03/078561 Pamphlet International Publication No. 02/012175 Pamphlet International Publication No. 02/012427 Pamphlet German patent No. 10038844 European Patent No. 1312665 German patent No. 10224509

  Surprisingly, even higher homologues (dimethylethylammonium acetonitrile tosylate) release trace amounts of trimethylamine under alkaline conditions. Depending on the alkali treatment, trace amounts of trimethylamine are detected even from N-methylmorpholinium acetonitrile methosulfate. The mechanism of formation is unknown, but probably one of the methyl groups attached to the nitrogen atom will uebertragen to the ammonia released as a result of nitrile hydrolysis. A trace amount of trimethylamine is formed by repeated movement of the methyl group.

  Surprisingly, N-methylammonium nitrile of the type described above with two ethyl substituents does not form trimethylamine under alkaline conditions despite the presence of one methyl group on the nitrogen. It has been found to be an effective bleach activator.

  Accordingly, the present invention provides a general formula

The resulting diethylaminoacetonitrile is taken up in water or an organic solvent and the corresponding N-cyanomethyl is obtained at a temperature of 20-100 ° C. using an alkylating agent such as methyl chloride, dimethyl sulfate or p-toluenesulfonic acid methyl ester. Convert to ammonium salt. Such salts can be obtained by conventional processing methods such as extraction, crystallization, suction filtration, washing of crystal mud on a suction filter, and drying. Similarly, it can be carried out from ethylmethylamine, in which case quaternization is carried out using an ethyl derivative.
2. React diethylmethylamine and chloroacetonitrile in a suitable solvent such as acetone at a temperature of 10-70 ° C. for 1-12 hours. The resulting precipitate N-cyanomethylammonium chloride is filtered, washed with an organic solvent and dried.
3. Diethylamine, sodium cyanide and formaldehyde or ketone, preferably formaldehyde in the form of a 36% formalin solution, are added together in a solvent, preferably an ethanol / water mixture or water. After 1-12 hours of reaction, an aqueous hydrochloric acid solution is added to the mixture at a temperature of 10-80 ° C, preferably 10-30 ° C. The aqueous phase is extracted using a suitable organic solvent such as methylene chloride or diethyl ether. After drying with magnesium sulfate, the solvent is removed from the combined organic phases. The resulting crude product can be further purified by fractional distillation. The resulting dialkylaminoacetonitrile is taken up in an organic solvent and converted to the corresponding N-cyanomethylammonium salt using an alkylating agent such as methyl chloride, dimethyl sulfate or arylsulfonic acid alkyl ester at a temperature of 20-100 ° C. Convert. Such salts can be obtained by conventional processing methods such as extraction, crystallization, suction filtration, washing of crystal mud on a suction filter, and drying. Similarly, it can be carried out from ethylmethylamine, in which case quaternization is carried out using an ethyl derivative.

  The present invention also provides a method for using these ammonium nitriles as bleach activators in detergents and detergents. In a particular embodiment, the diethylmethylammonium acetonitrile of the present invention is used in detergents and detergents in the form of granules. Such granules can comprise 5 to 95% by weight, but preferably 20 to 90% by weight of the diethylmethylammonium acetonitrile of the present invention.

For the production of granules, granulation aids (Granulierhilfsmittel) and / or coating substances can additionally be used.

  As used herein, the phrase “bleaching” means both bleaching of soil present on the surface of the fiber material and bleaching of soil present in the cleaning liquid separated from the surface of the fiber material.
