Micellar catalysis with various polyoxyethylated compounds was used to synthesize sodium allyl sulfonate by the reaction of allyl chloride with an aqueous solution of sodium sulfite. It was shown that methoxy polyethylene glycol methacrylates and water soluble polymers based on these compounds are surfactants and can be used to intensify the synthesis of sodium allyl sulfonate, which is of interest in the case of its subsequent application to obtain copolymers with methoxy polyethylene glycol methacrylates.

Paragraph 0023-0034, (2019/02/04)
The invention discloses a synthesis method of sodium allysulfonate. The synthesis method comprises the following steps: adding a phase transfer catalyst and a polymerization inhibitor into a sodium pyrosulfite solution, uniformly stirring and mixing, thus obtaining a sodium pyrosulfite mixed solution, and simultaneously introducing the sodium metabisulfite mixed solution, a sodium hydroxide solution and allyl chloride into a reactor to react, thus obtaining a target product. According to the synthesis method, by changing the feeding sequence of the raw materials, the raw materials anticipatingin the reaction simultaneously enter the reactor to react, and the phase transfer catalyst and polymerization inhibitor are added, so that the side reaction can be greatly reduced, the selectivity and the conversion rate of the reaction can be improved, and the yield of products can be improved; and compared with a traditional method, the method does not need the subsequent steps of dehydration,active carbon discoloration, impurity removal and the like, the subsequent treatment steps are simple, the production cost is reduced, the production efficiency is improved, and the synthetic method of the sodium allysulfonate is more suitable for the industrialized production.
