Method for preparing sodium 2,3-dimercapto-1-propanesulfonate

The invention belongs to the technical field of drug synthesis, and in particular relates to a method for preparing sodium 2,3-dimercapto-1-propanesulfonate. With sodium allysulfonate used as a starting material and through a bromination reaction, a sulfhydrylation reaction, a lead salt reaction and a lead removal reaction, high-content sodium 2,3-dimercapto-1-propanesulfonate is obtained by refinement. The total yield is 23.2% and above; especially when zinc dust reduction step is added after hydrolysis, the yield can be greatly increased, the total yield can reach 35-41.5%, and the refined sodium 2,3-dimercapto-1-propanesulfonate content reaches 99% and above. Ethanethioic acid potassium salt is used as a sulphurizing agent and then is hydrolyzed under strong acid conditions, and dilutesulfuric acid is used for lead removal after lead formation. During the whole reaction and treatment process, toxic gas hydrogen sulfide which affects the environment is prevented from being used or generated. Thereby, working conditions are improved, emission of three wastes is reduced, and production efficiency is enhanced.
