摘要： A fluorocarboxylic acid preparation process which includes hydrolyzing fluorocarboxylic acid fluoride in the presence of an aqueous sulfuric acid solution to form a reaction product containing a fluorocarboxylic acid and hydrogen fluoride (present as hydrofluoric acid); and removing at least some of the hydrogen fluoride from the reaction product by washing the reaction production with aqueous sulfuric acid solution. The hydrolyzing and washing are carried out at a temperature at which the fluorocarboxylic acid is a liquid.

摘要： Procédé de préparation d'un hydrochlorofluorocarbone ne renfermant pratiquement pas d'impuretés oléfiniques dans lequel on effectue l'hydrogénation des impuretés oléfiniques. On peut contrôler ce procédé de manière à ce qu'au moins une partie de l'hydrochlorofluorocarbone soit transformé en un fluorohydrocarbone.
