PROCESS FOR THE PREPARATION OF 1,3-PROP-1-ENE SULTONE

摘要

A method for producing a 1,3-prop-1-ene-sultone which is used as a electrolyte of secondary lithium battery is provided to simplify the chemical synthesis without harmful chemical reaction. A method for producing a 1,3-prop-1-ene sultone comprises: a step 1 of chlorinating POCl3 or PCl5 with a compound of the chemical formula 2 to produce a compound of the chemical formula 3; a step 2 of diluting the compound of the chemical formula 3 and bromodan (1,3-Dibromo-5,6-dimethylhydantoin) in dichloroethylene solvent and stirring at 20-30°C for four to eight hours to produce 2-halo-1,3-propan sultone of the chemical formula 4; and a step 3 of adding base in the 2-halo-1,3-propan sultone of the chemical formula 4 and stirring for four to eight hours to produce a 1,3-propo-1-ene sultone of the chemical formula 1.
