DESCRIPTION OF THE INVENTION: FIELD OF THE INVENTION The present invention relates to a process for the exchange of anions of quaternary alkyl ammonium salts with different anions, more particularly with respect to removal of bromide ions by insoluble metal bromide , a method of exchanging bromide ions of a quaternary tetraalkylammonium bromide with different anions. [Prior Art] A quaternary ammonium salt (Quat) is not precisely defined as a group of compounds which connects a nitrogen atom to four organic atomic groups. Due to the net positive charge on the nitrogen atom in the quaternary ammonium compound, it is often found that the quaternary ammonium salt is associated with one or more anions. The associated anion is called a counterion, and the combination of a quaternary ammonium compound and an anion is called a quaternary ammonium salt. Quaternary ammonium salts are compounds of various groups that are utilized not only in the wood preservative/biocide industry, but also in such industries as hair care products, cleaning products, fabric softeners, drugs, surfactants, Odors, mouthwashes, preservatives, emulsifiers, cosmetics and mining. The use of the quaternary ammonium salt compound is generally described in U.S. Patent Nos. 3,301,815, 3,366,672, 4,365,030 and 4,444,790. Methods of making quaternary ammonium salt compounds are well known in the art. Basic chemistry textbooks teach that the final product of the reaction of ammonia or an amine with an alkyl halide is a quaternary ammonium salt.

A number of other publications are exemplified by the US Patent Nos. 5, 3 0 8, 3 6 3 ' 5, 4 3 8, 0 3 4 ' 5, 5 23, 48 7 ' 5, 8 5 5, 8 1 A specific method for making a quaternary ammonium salt having a particular type of substituent and a particular counterion is reported in U.S. Patent Nos. 6,784,317, 6, 090, 855, 6, 485, 790, and U.S. Patent Application Serial No. 2 0 0 3 /002 3 1 0 8 . Even from the viewpoint of a method known for producing a quaternary ammonium salt, there is a need to improve the method for producing a quaternary ammonium salt, especially a commercially applicable method. The present invention satisfies the above needs by providing an indirect synthesis method which can be used to prepare various tetra(anthracene to C2.) alkyl or aryl substituted alkyl quaternary ammonium carbonate and bicarbonate compounds, for example, , di C ) dimethylalkyl quaternary ammonium carbonate and bicarbonate compounds. The method of the present invention comprises (a) combining at least four (C 1 to C 2 fluorene) alkyl or aryl substituted terphenyl ammonium bromide, metal hydroxide and having less than 1 gram of solvent per gram of solvent A solvent of about 1 gram of solubility of the metal bromide which is stoichiometrically excess relative to the fourth grade ammonium bromide to produce at least four cc to C2. An alkyl or aryl substituted alkyl quaternary ammonium hydroxide; and (b) combining at least the tetra (C, to C2.) alkyl or aryl substituted alkyl quaternary ammonium hydroxide and carbon dioxide An alkyl quaternary ammonium carbonate substituted with at least the four (匕 to c2 〇) alkyl or aryl group is produced. SUMMARY OF THE INVENTION Applicants' methods can be roughly exemplified as follows: 200920696 (I)· x[(R1R2R3R4N)+]Br'+ excess M(OH)x + R5OH x[(R1R2R3R4N)+]OH+MBrx+ residual M ( OH)x+R5OH; and (II}-[(r1r2r3r4n)+]oh-+ residual M(OH)X + C02 + R5OH —> [(R1R2R3R4N)+]HC03_ + [(R1R2R3R4N)+]2C〇32 '+ M2(C03)x+ r5〇h , wherein M2(C〇3) X in the formula (I) is in the solvent R5OH, and is removed by, for example, filtration; each R1 , R2, R3 and R4 are independently C! to C2. Alkyl or aryl substituted alkyl (for example, R1 and R2 may be different C8-C12 alkyl groups and R3 and R4 may each be methyl, etc.) Alkyl, hydrazine is a mono-, di- or trivalent metal, or an alkali metal; if Μ is a unit price, X is 1; if Μ is divalent, X is 2; if Μ is trivalent, X is 3. Therefore, alkali The metal is like Na or yttrium, and X is 1. (^ to C2. alkyl or aryl substituted alkyl, C, to C2. alkyl or aryl substituted alkyl, dimethyl tetraammonium bromide In combination with a stoichiometric excess of metal hydroxide in a suitable solvent, for example, having less than about 1 gram of gold per 00 gram of solvent a solvent for the solubility of bromide, and a Cl to C2 in the i-rich. A yard- or aryl-substituted yard, Cl to C2. Alkyl or aryl-substituted alkyl, dimethyl quaternary ammonium hydroxide Intermediate solution. The hydroxy quaternary ammonium salt intermediate and the residual metal hydroxide in the solution are combined with carbon dioxide to produce a quaternary ammonium carbonate/bicarbonate and an insoluble metal carbonate. Suitable solvents include R5 sterols. For example, methanol, ethanol, isopropanol, propanol, isobutanol, and other C, to C6 alcohols. Tetraallammonium salts having any desired anion (eg, phosphate, acetate, salicylate, grass) Acidates, chlorides, etc. can be prepared by combining an ammonium hydroxide intermediate with a corresponding acid. 200920696 Many (^ to C2. alkyl or aryl substituted alkyl, (^ to c2. alkyl or aryl) Substituted alkyl, dimethyl quaternary ammonium bromide is a suitable reactant for the preparation of a hydroxy quaternary ammonium salt intermediate, such as dimercaptodimethylammonium bromide. Suitable for the brominated quaternary ammonium salt reactant. The choice of the 1 and R2 substituents is determined by the intermediate of the hydroxy quaternary ammonium salt. a factor, and thus a determinant of the carbonate quaternary ammonium salt product. Many other tetraalkyl fourth ammonium bromides are also suitable for use in the present invention, as is known to those skilled in the art. The methods exemplified are those wherein R1 is methyl, C8 alkyl, CN isoalkyl, G. alkyl, Cl2 alkyl, Cm alkyl, C16 alkyl or benzyl; R2 is already. An alkyl group, a C2 alkyl group, a C"alkyl group or a C16 alkyl group: and each of R3 and R4 is a methyl group. The metal hydroxide reactant may be a mono-, di- or trivalent metal hydroxide or an alkali metal hydroxide. For example, sodium hydroxide or potassium hydroxide. The first step reaction product of the metal bromide can be easily removed by filtration or the like to produce a hydroxy quaternary ammonium salt/solvent reaction product. If desired, hydroxy quaternary ammonium The salt may be isolated therefrom by drying or the like. The first reaction (I) may be carried out in a solvent including a Chq alcohol such as ethanol or absolute ethanol. The reaction for forming a hydroxy quaternary ammonium salt is typically an equilibrium reaction 'but an alcohol solvent The use rapidly drives the reaction to a quaternary ammonium quaternary ammonium salt. The amount of metal hydroxide reactant can be stoichiometric relative to the tetraalkyl fourth ammonium bromide reactant. Therefore, on a theoretical basis, if the reaction It is completely and unbalanced, and when the intermediate reaction is completed, there will be no excess of the metal hydroxide reactant of 200920696. In fact, when using the chemist metal hydroxide reactant, the yield is It will vary from about 65% to but some will be based on each metal oxide reactant. By using a metal hydroxide ranging from about 2% to about 50% excess, the yield of hydroxy quaternary ammonium salt can be compared. A further improvement. If an excess of metal hydroxide is used, the yield is about 95% to about 99%, as described above, and the unreacted metal hydroxide is soluble in the hydroxy quaternary | intermediate. The hydroxy quaternary ammonium salt and any unreacted gold species can be reacted with at least a stoichiometric amount of carbon dioxide to produce an acid salt, and if any unreacted metal hydroxide metal carbonate is present. The medium conversion metal hydroxide carbonate ' is the fastest. The metal carbonate can be precipitated and easily separated by filtration or the like, leaving a stable quaternary ammonium carbonium hydrogen salt or a quaternary ammonium carbonate/solvent reaction product. As illustrated, the carbonation step also produces quaternary ammonium as a by-product. Separate quaternary ammonium carbonate or quaternary ammonium carbonate is suitable for use in, for example, wood preservative systems. These quaternary ammonium carbon grades. The carbonate/bicarbonate composition does not require stabilization of the matrix of the metal affinity agent. The wood preservative system may be free of metal. The mixing, addition, combination and reaction of the components of the present invention may be carried out by conventional methods well known to those skilled in the art. The order of addition of any reactants or solvents does not affect the amount of the method or the amount of the program is about 95%, and the method of adding sT to increase the self-crossing salt/solvent is quaternary ammonium hydroxide, the product becomes The gold may be passed through the usual individual steps via a salt of a salt/bicarbonate hydrogenate or a mixture of four for wood. The anti-9-200920696 reagent and/or solvent may be added to any suitable reaction vessel continuously or simultaneously. For example, a metal hydroxide can be dissolved in an alcohol and the resulting mixture can be added to the bromide quaternary ammonium salt or the bromide quaternary ammonium salt can be dissolved in the alcohol and the metal hydroxide added to the resulting mixture. Importantly, the method of the present invention is suitable for commercial scale manufacturing techniques and equipment, and is convenient for small scale operations. Typically, the bromide quaternary ammonium salt is converted to a hydroxy quaternary ammonium salt reaction (I) and the solvent is stirred and heated from about 20 ° C to about 7 ° C and maintained at that temperature for about 1 hour to about 5 hours period. The reaction mixture is then cooled, first to room temperature and then to about οπ, which is maintained at this temperature for about 1 hour to about 2 hours. Any precipitated metal bromide is collected, for example, via filtration, as is well known in the art. According to the invention, the exemplified step comprises the manufacture of a quaternary ammonium hydroxide solution by treating the quaternary ammonium bromide solution with KOH and precipitating KBr, and converting the quaternary ammonium hydroxide in the solution to bicarbonate/ Carbonate. Several other quaternary ammonium salts (i.e., phosphates, carboxylates, other halides, etc.) can be prepared from the quaternary ammonium hydroxide intermediate. 1 - or 1 2 -butanol can be used as a solvent for producing a four-stage ammonium bromide solution and in order to obtain a low bromine hydrazine, water can be removed from the KOH solution of butanol. When water is stripped from the butanol solution of KOH, KOBu is formed. The dried KOH solution was mixed with a substoichiometric amount (1.5 mol KOH/mole bromide) of a four-stage ammonium bromide solution to precipitate KBr. The quaternary ammonium butoxide/hydroxide solution is then treated with a C 〇 2 gas to obtain a solution of a carboquat (carbonate/bicarbonate/butyl carbonate) in butanol. Excess KOH/KOBu in the ammonium hydroxide solution was precipitated into a carbonate--10-200920696 salt using a C〇2 treatment and removed from the furnace. Initially no water was used, then the butanol from the quaternary ammonium carbonate solution was stripped using water and treated with a small amount of 5 〇 % H 2 〇 2 to decolorize the yellow solution. The resulting clear quaternary ammonium carbonate solution (carbonate/bicarbonate) can then be diluted with sufficient water and i,2-propylene glycol to meet the desired specifications. Thus, in one aspect of the invention, a method for preparing a quaternary mirror carbonate solution substituted with a low alkyl halide and a good color of about 50% aqueous tetraalkyl or aryl substituted. The method comprises: (i) a solution of a quaternary ammonium bromide from a decyl dimethylamine and a 1-bromodecane in a C4 alcohol, (U) comprising from a quaternary ammonium salt of more than 1 mole of KOH/mole.

It should be understood that the invention is not limited to any specific embodiment exemplified herein, whether in the examples or in the remainder of the patent application. -11- 200920696 - Example 1 - Preparation of a quaternary phosphonium bromide solution 93 g (0.5 mol) of N,N-dimethyl decylamine, lllg (0.5 mol) of 1-bromodecane and 1 3 5 A mixture of g of butanol was poured into a dry 5 〇〇 ml flask equipped with a condenser. The mixture was heated to reflux using an electric hood. Stop heating after 4 hours. A clear pale yellow solution of the quaternary ammonium bromide was analyzed. Analysis shows 12.7 wt% bromine, 0.19 wt% free amine and 59.4 wt% quaternary ammonium hydrazine. In 65 g of 2-butanol, 93.5 g (0.5 mol) of decyl dimethylamine f solution was placed in a flask and heated. To 1 〇 5 t with magnetic stirring. 1-bromodecane (1 1 1 .5 g) was added dropwise over 2 hours and the mixture was heated at 105 t for an additional 4 hours. Analysis of the clear yellow solution (269 g) found to have 70.6 wt% quaternary ammonium salt, 13.2 wt% bromine, and 0.88 wt% free amine. Example 2 - Preparation of an alkyl quaternary ammonium solution in butanol A 10 g (150 mmol) piece of potassium hydroxide containing about 15 wt% water, 50 g of 1-butanol and 25 g of hexane was added to a 250 ml flask. The flask was equipped with a Dean-Stark trap and a reflux condenser. The mixture was refluxed and the water removed as azeotrope was collected in a trap. The mixture was refluxed until the aqueous phase in the trap did not increase. 60 g (about 90 mmol) of the quaternary ammonium bromide solution was added dropwise to the solution at ambient temperature and magnetically stirred. The mixture was then cooled in an ice bath for 1 hour. The precipitated solid particles were filtered under suction and washed with 20 ml of hexane. The slightly cloudy filtrate was again filtered to obtain a clear solution. C0 2 gas was bubbled through the solution for 1 hour. The precipitated solid particles were removed by passing through a Whatman filter paper to obtain 100 g of a clear yellow solution of alkyl quaternary ammonium in 1-butanol. Analysis showed that the -12-200920696 alkyl quaternary ammonium solution had 33.2% quaternary ammonium salt and 345 ppm bromine. Example 3 - Preparation of alkyl quaternary ruthenium 7k solution A sample of 〇6g of a solution of quaternary ammonium carbonate in 1 - butanol containing 2,300 ppm of bromine (3 4 · 8 wt %) was placed in a 500 ml flask and Concentrate to about 60 g at 7 ° C under vacuum using a rotary evaporator. Deionized water (40 g) and 1,2-propanediol (6 g) were added to the mixture and concentrated to about 6 5 2 ° using a rotary evaporator, diluted three times with 40 g of water and concentrated to about 65 g. The resulting pale yellow solution was mixed with 3 g of a 50 wt% hydrogen peroxide solution and diluted to 74 g with water. The clear, colorless solution obtained had a Gardner color of 1 and contained 2 94 ppm bromine (1 30 ppm chlorine) and 5 1 .Owt% quaternary ammonium salt. Details of the quaternary ammonium carbonate: quaternary ammonium salt = 48.5 to 5 1.5 wt%; Gardner color 値 = <4; halide = < 3 0 0 p p m is a chloride.
