Participants

Reaction Steps

In a four necked 1 liter flask equipped with a thermometer, a condenser and a stirrer, 1-chloromethoxy-1,1-difluoro-2-trifluoromethyl-3,3,3-trifluoropropane (276.6 g, 1.04 mol) and water (18.7 g, 1.04 mol) were charged, and concentrated sulfuric acid (74.8 g, 0.76 mol) was dropwise added thereto while stirring The reaction was continued at 110° C. for 20 hours. Then, the reaction mixture was distilled to give monochloromethyl 2-trifluoromethyl-3,3,3-trifluoropropanoate (187.8 g).
