Trifluoromethanesulfonyl Fluoride CAS No 335-05-7

Application

Preparation：

A 500mL pressure-resistant reaction jar was filled with 103g (1.78mol) of 1% aqueous potassium fluoride, cooled with ice water to 5°C, and then vacuum-degassed. Trifluoromethanesulfonyl chloride (100 g, 0.595 mol) was added. Seal the reactor, raise the temperature gradually, and stir it for four hours once the internal temperature reaches 40 to 50°C. The Chemicalbook reactor pressure is at 0.94 MPa. Before being caught by a trap cooled by liquid nitrogen, the gas from the reactor circulates in a condenser that is chilled to between -40°C and -20°C. 80.3 g of the collected product yielded 88% (conversion rate 99%, selectivity 89%) and 98.9% purity for trifluoromethanesulfonyl A 500mL pressure-resistant reaction jar was filled with 103g (1.78mol) of 1% aqueous potassium fluoride, cooled with ice water to 5°C, and then vacuum-degassed.
