The present invention provides a process for producing highly pure fluoro-compounds by making use of N-(2-chloro-1,1,2-trifluoroethyl)diethylamine. The process produces little or no chlorinated by-products. The present invention provides a process for producing a fluoro-compound, comprising fluorinating an alcohol derivative represented by the following general formula (I): RRRCOH (I), (wherein Rrepresents a hydrogen atom, a substituted or unsubstituted alkyl group, aryl group, alkylcarbonyl group, alkoxycarbonyl group, arylcarbonyl group or aryloxycarbonyl group; and Rand Rare each independently a substituted or unsubstituted alkyl group, aryl group, alkylcarbonyl group, alkoxycarbonyl group, arylcarbonyl group or aryloxycarbonyl group, wherein at least two of R, Rand Rmay together form part of a ring structure, either with or without a heteroatom) with N,N-diethyl-2-chloro-1,1,2-trifluoroethylamine to form a fluoro-compound represented by the following general formula (2): RRRCF (2), (wherein R, Rand Rare as defined above), the process being characterized in that an alcohol derivative represented by the following general formula (3): ROH (3), (wherein Rrepresents a substituted or unsubstituted alkyl group or aryl group) is added to the reaction system.

Process for producing fluoro-compounds

A catalyst for oxidizing 2,2,2-trifluoroethanol to form trifluoroacetaldehyde. The catalyst has a long life and achieves high conversion and selectivity. The catalyst of the present invention comprises one or more metal oxides, including at least vanadium oxide, and zirconia as a carrier.
