반응 단계
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), silicon dioxide and fluorosulfuric acid (70.0 g, 0.70 mol) were charged. The reaction was continued at 110° C. for 21 hours. Then, the reaction mixture was distilled to give monochloromethyl 2-trifluoromethyl-3,3,3-trifluoropropanoate (190.3 g).
