PURPOSE: To produce the titled compound useful as a thermal medium, etc., in high yield, by the Cannizzaro reaction of a perfluoroaldehyde in the presence of a catalyst comprising a compound of an element selected from Mg, Ca, Sr and the elements of the IIIA-group of the periodic table. n CONSTITUTION: A polyfluoroalcohol such as trifluoroethanol is produced from a perfluoroaldehyde such as trifluoroacetaldehyde, pentafluoropropionaldehyde, etc. When a compound of an element selected from Mg, Ca, Sr and elements of the III-group of the periodic table (e.g. B, Al, Ga, etc.) is used as a catalyst, and a reaction medium such as water, alcohol, ketone, etc. is used as the reaction medium, the Cannizzaro reaction proceeds and an intermolecular oxidative cyclization reduction reaction takes place. A perfluorocarboxylic acid can be produced by this reaction in combination with the polyfluoroalcohol. n COPYRIGHT: (C)1985,JPO&Japio |
