Claims6
A process for producing trifluoroacetaldehyde and/or a trifluoroacetaldehyde hydrate, comprising oxidizing 2,2,2-trifluoroethanol with molecular oxygen or a molecular oxygen-containing gas in a gas-phase oxidation process carried out in the presence of a catalyst comprising one or more metal oxides, including at least vanadium oxide and zirconia as a carrier.
A process for producing trifluoroacetaldehyde and/or a trifluoroacetaldehyde hydrate, comprising oxidizing 2,2,2-trifluoroethanol with molecular oxygen or a molecular oxygen-containing gas in a gas-phase oxidation process carried out in the presence of a catalyst comprising one or more metal oxides, including at least vanadium oxide and tin oxide, and zirconia as a carrier, wherein the gas phase oxidation process is carried out at a temperature of 200 to 400° C., and further wherein the zirconia has a specific surface area in the range of 10-200 m2/g.
