一种全氟聚醚酰氟水解过程乳化现象解决方法
摘要：
一种全氟聚醚酰氟水解过程乳化现象解决方法，它涉及一种乳化现象解决方法，具体涉及一种全氟聚醚酰氟水解过程乳化现象解决方法。本发明为了解决全氟聚醚酰氟水解过程中乳化现象的问题。本发明的具体步骤为：步骤一、将全氟聚醚酰氟Rf-COF溶解在含氟溶剂中；步骤二、加入蒸馏水室温搅拌，使全氟聚醚酰氟水解成全氟聚醚羧酸；步骤三、加入氟碳醇就可以破坏全氟聚醚酰氟水解过程中出现的乳化层，使水层和有机层完全分开。本发明属于化工领域。
摘要（英）：

The invention relates to an emulsion solution method, in particular to a solution method for emulsion in the perfluoropolyether acyl fluoride hydrolysis process. The solution method aims to solve the problems of emulsion in the perfluoropolyether acyl fluoride hydrolysis process. The method comprises the specific steps that 1, perfluoropolyether acyl fluoride Rf-COF is dissolved into fluorine-containing solvent; 2, distilled water is added, and the mixture is stirred at the room temperature, so that perfluoropolyether acyl fluoride is hydrolyzed into perfluoropolyether carboxylic acid; 3, fluorocarbon alcohol is added so that an emulsion layer occurring in the perfluoropolyether acyl fluoride hydrolysis process can be destroyed, and a water layer and an organic layer can be separated completely. The method belongs to the field of chemical industry.
