Abstract
The present invention belongs to a synthetic method of 2-acrylamide-2-methylpropanesulfonic acid. In the present invention, acrylonitrile, isobutylene and sulfuric acid are used as raw materials. By the addition of organic estolide and the introduction of isobutylene, an AMPS product with higher purity is obtained through one-step reaction.
Description
The invention belongs to the preparation method of 2-acrylamido-2-methyl propane sulfonic acid.
The vinyl monomer and the polymkeric substance that have sulfonic acid group, owing to have the special performance of strong acid, application has in some aspects become irreplaceable monomer and polymkeric substance, especially acrylamide group methyl propane sulfonic acid, be at present the amide group sulfonic acid monomer that can make high-molecular weight polymer only to be arranged, and just realize commercial production in the recent period.Because this monomer and polymkeric substance be to hydrolysis, temperature and the cationic stability of two valencys, its range of application aspect oil field, water treatment industry is more and more wider, and importance is different more obviously, and through various countries scholar's research for many years, its synthetic expense is far below styrene sulfonic acid.It is a water-soluble monomer with broad prospects for development.
Such monomeric synthesizing sees United States Patent (USP) 2,983 the earliest, and 712 (1961), this patent is with acrylate chloride (CH
2=C-C-Cl) same Armeen (RNH
2) and sulfonic acid (R-SO
3H) synthesize by reacting usually for raw material.English Patent 995802 (1965) and United States Patent (USP) 3,332,904 (1967) have also reported similar synthetic method.1967 HOII P 6,611,091 (corresponding English Patent 1,090,779) reported the synthetic method of 2-acrylamido-2-methyl propane sulfonic acid (AMPS) first.This method is that iso-butylene is fed in the mixed solution of vinyl cyanide and chlorsulfonic acid, steams excessive propene nitrile and iso-butylene after the reaction, is dissolved in the methyl alcohol recrystallize and makes pure product.United States Patent (USP) 3,506,707 (1970) propose to use SO
3With the mixture of acetic acid with the iso-butylene reaction earlier that is dissolved in acetic acid and the methylene dichloride, and then add the method that two-step approach that entry, vinyl cyanide and sulfuric acid continues to react is produced AMPS.United States Patent (USP) 3,544,597 (1970) German Patents (1971) 2,105,030, (1976) 2,523,616 have all reported the method for preparing AMPS with oleum with vinyl cyanide and isobutene reaction.The method that these patents are reported all obtains highly purified AMPS monomer.Japan Ri Dong chemical company is a method of having improved U.S. lubricant corporation (German Patent 2,105,030,1971), and respectively Germany and Japanese publication patent; 2,904,444; 2,904,465 JP 81-53306; 53307, the described method of this patent is with excessive vinyl cyanide double as reaction solvent, adds oleum in helium-atmosphere under low temperature, under agitation feed iso-butylene, make its reaction, product A MPS separates out from reaction mixture, obtain the muddy product, add acetic acid then and heat up, steam the excessive propene nitrile, add certain water gaging again, be warming up to and make its dissolving more than 90 ℃, put into cold water again, the product crystallization is separated out, and clean with acetic acid, use 60 ℃ of warm air dryings again, promptly get high-purity monomer.Though this method is a method preferably at present, when synthetic, very easily generates yellow by product, acetic acid is difficult to remove from product, and oleum and acetic acid have very strong corrodibility and volatility again.Be easy to contaminate environment and etching apparatus.
The purpose of this invention is to provide a kind of compound that in reaction mixture, adds the organic acid anhydride class, make the monomeric preparation method of the higher AMPS of purity by vinyl cyanide, sulfuric acid and iso-butylene single step reaction.
The present invention adds reactor simultaneously with vinyl cyanide, iso-butylene and three kinds of materials of sulfuric acid, or sulfuric acid is fed iso-butylene in the adding vinyl cyanide earlier again.Organic acid anhydride can add in vinyl cyanide or the sulfuric acid or add in the mixture.Under low temperature or room temperature, in vinyl cyanide, add organic acid anhydride earlier and add sulfuric acid again, the add-on of organic acid anhydride is the 0.5-50% of sulfuric acid add-on, be preferably 2-25%, feed iso-butylene in being lower than under 75 ℃ the temperature, suitable temperature is 30～50 ℃, and temperature of reaction can be controlled by the feeding amount of iso-butylene.The AMPS product that generates is directly separated out from reaction mixture, is chilled to room temperature, separates solid-liquid with suction filtration or whizzer, and cleans crystallization with vinyl cyanide, promptly obtains white powdered product after the drying.
The present invention adds organic acid anhydride when using sulfuric acid not only can improve product yield, and the product crystalline particle is bigger, very easily separates out from reaction mixture, be easy to suction filtration and separate, and available vinyl cyanide cleans, and vinyl cyanide only needs that simple distillation was both recyclable to be used again.And method of the present invention is not used severe corrosive and volatile material, therefore, and etching apparatus not, pollution-free refuse.
