The present invention is a production method of a fluoroethercarboxylic acid fluoride, comprising the step of selectively producing a fluoroethercarboxylic acid fluoride represented by the formula (I): CF3O(CF(CF3)CF2O)CF(CF3)COF (I) by reacting hexafluoropropylene oxide with carbonyl fluoride in a solvent at a temperature of -30 to 40 °C in the presence of a catalyst, wherein the catalyst comprises at least one species selected from the group consisting of metal fluorides, tertiary amines, tertiary diamines and tetraalkylammonium salts, and the solvent is an aprotic polar solvent.
本发明是一种氟醚羧酸氟的生产方法,包括以下步骤:在溶剂中,在催化剂的存在下,通过反应六氟丙烷氧化物和羰基氟,以选择性地生产由式(I)表示的氟醚羧酸氟:CF3O(CF(CF3)CF2O)CF(CF3)COF (I)。其中,催化剂包括金属氟化物、三级胺、三级二胺和四烷基铵盐中至少一种物种,溶剂为无水极性溶剂,反应温度在-30到40°C之间。
