Claims
- 1. A process for producing secondary-butyl perfluoroesters comprising reacting ethylene and a perfluorocarboxylic acid in the presence of oxygen and a Group VIII metallic catalyst at a pressure of 500 to 1,000 psig and temperature from about 100.degree. C. to 200.degree. C., the molar ratio of said perfluorocarboxylic acid to ethylene ranging from about 1:5:1 to 10:1.
- 2. The process of claim 1 wherein the amount of oxygen ranges from about 0.0001 to about 20 mole percent of the total gases present.
- 3. The process of claim 2 wherein the Group VIII metallic catalyst is selected from the group consisting of palladium, platinum and ruthenium.
- 4. The process of claim 3 wherein the perfluorocarboxylic acid is trifluoroacetic acid.
- 5. The process of claim 4 wherein the metallic catalyst is palladium.
