Paragraph 0019-0024, (2018/10/19)
The invention provides a preparation method of a trimethyl-sulfonium-hydrocarbonate solid. The synthesis method comprises the steps that a trimethyl-sulfonium-chloride alcohol solution is mixed and reacts with an equimolar ratio of sodium hydroxide alcohol solution at -5-40 DEG C, filtration is carried out to prepare a trimethyl-sulfonium hydroxide alkaline alcohol solution, then a slight excess of carbon dioxide gas is introduced until the pH value of a reaction liquid is 7.5-8.5, then an alcohol solvent is removed under reduced pressure to obtain a trimethyl-sulfonium-hydrocarbonate solid product, and the yield can reach 96% or above. The synthesis method has the advantages that the operation is simple, the environmental pollution is small, the yield is high, and the method is suitable for industrial production.
