High-purity fluoromethyl p-toluenesulfonate production process

The invention relates to the field of chemical synthesis, in particular to a high-purity fluoromethyl p-toluenesulfonate production process, which comprises fluoromethyl p-toluenesulfonate productionand toluenesulfonate production. The fluoromethyl p-toluenesulfonate production comprises the following steps of S1, melting: putting p-toluenesulfonate into a melting tank with stirring and heating functions, meanwhile, adding a specified amount of water, starting a motor on the melting tank to stir p-toluenesulfonate, and meanwhile, starting the heating function of the p-toluenesulfonate, and S2, pressurizing and fusing: pouring the molten p-toluenesulfonate liquid into a pressurizing tank, and adding a catalyst copper trifluoromethanesulfonate into the pressurizing tank. The production process has the beneficial effects that the molar ratio of fluoroX methane to p-toluenesulfonate is 1: 1, a nucleophilic substitution principle is adopted, and one-step reaction is carried out, so that the synthesis process is si
