Abstract
A process for the preparation of 2,2,2-trifluoroethanol which comprises reacting 2-chloro-1,1,1-trifluoroethane with an alkali metal salt of a carboxylic acid in a substantially anhydrous aprotic solvent thereby to form the carboxylic acid ester of 2,2,2-trifluoroethanol and an alkali metal chloride, reacting the ester with the hydroxide or a basic salt of the alkali metal in water thereby to form 2,2,2-trifluoroethanol and the alkali metal salt of the carboxylic acid, separating the 2,2,2-trifluoroethanol, and recycling the alkali metal salt of the carboxylic acid for further reaction. Advantageously the alkali metal salt is potassium acetate, the aprotic solvent is N-methyl-2-pyrrolidone and the reaction in the N-methyl-2-pyrrolidone is effected at about 150.degree. to 180.degree.
