Yield: 75.9%

Reaction Conditions:

with bis(2,2,2-trifluoroethyl) sulfate;hydrogen fluoride at 80; for 8 h;

Steps:

7 A method for preparing methyl fluorosulfonate comprises the following steps:
Add 261.0 g of methyl chlorosulfonate to a 500 mL PTFE reactor.Turn on the agitation. 10 g of bistrifluoroethanol sulfate was added and the temperature was raised to 80 ° C.Approximately 40g of anhydrous hydrogen fluoride gas is introduced at a constant rate.Maintain the reaction temperature at 80 ± 5 ° C,The reaction was stopped for 8 hours, the reaction was stopped, and hydrogen fluoride was removed by nitrogen.Atmospheric distillation, collecting fractions at 92-93 ° C173.4g,Purity 99.1%,The yield was 75.9%.
