It is one of the strongest acids. Triflic acid is mainly used in research as a catalyst for esterification. It is a hygroscopic, colorless, slightly viscous liquid which is soluble in polar solvents. ==Synthesis== Trifluoromethanesulfonic acid is produced industrially by electrochemical fluorination (ECF) of methanesulfonic acid: :CH3SO3H + 4 HF → CF3SO2F + H2O + 1.5 H2 The resulting CF3SO2F is hydrolyzed, and the resulting triflate salt is preprotonated. Alternatively, trifluoromethanesulfonic acid arises by oxidation of trifluoromethylsulfenyl chloride: ::CF3SCl + 2 Cl2 + 2 H2O → CF3SO2OH + 4 HCl Triflic acid is purified by distillation from triflic anhydride.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trifluoromethanesulfonic acid」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
