| titleOfInvention | Preparation of 1-chloro-2-trifluoro-methyl-3,3,3- trifluoropropene from isobutylene |
| abstract | 3,3, 3-TRIFLUOROPROPENE FROM ISOBUTYLENE ABSTRACT OF THE DISCLOSURE Isobutylene is catalytically converted to 1-chloro-2-trifluoromethyl-3,3,3-trifluoropropene [(CF3)2C = CHCl] in a chlorofluorination reaction zone by passing a mixture of anhydrous hydrogen fluoride, chlorine and the isobutylene over a chromium oxide or metal fluoride chlorofluorination catalyst. Alterna-tively, the isobutylene feed is first prechlorinated, and the mixture of prechlorination fed for conversion to the desired (CF3)2C = CHCl, to a downstream fluorination reactor charged with the chlorofluorination catalyst. The 1-chloro-2-trifluoromethyl-3,3,3-trifluoropropene product is of value as an intermediate in the preparation of hexafluoroisobutylene. |
