Method for preparing 2-methyl-1,3-propane sultone

The invention discloses a method for preparing 2-methyl-1,3-propane sultone. The method comprises the following steps: (1) mixing 2-methyl-1,3-propylene glycol with a chlorinating agent, performing achlorination reaction at a certain temperature, and after the reaction is completed, concentrating and removing the solution so as to obtain 2-methyl-1,3-propylene dichloride; (2) mixing the obtained2-methyl-1,3-propylene dichloride with a sulfonating agent and a solvent, increasing the temperature to implement a sulfonation reaction, and stirring till the reaction is completed so as to obtain 2-methyl 3-sodium chloropropyl sulfonate; (3) putting the obtained 2-methyl 3-sodium chloropropyl sulfonate into water, adding a strong acid to adjust the pH value to be 1-3, performing acidification treatment, removing inorganic salts through concentration and filtration, and further concentrating till dryness so as to obtain 2-methyl-3-chlorine propanesulfonate; (4) heating the obtained 2-methyl-3-chlorine propanesulfonate under a vacuum condition, performing dehydrochlorination, and performing an internal esterification reaction, so as to obtain 2-methyl-1,3-propane sultone. The method has the advantages of being small in raw material toxicity, cheap in raw material, easy in raw material obtaining, easy in on-scale production, high in product purity, high in product yield, and the like.
