Preparation of 1-chloro-2-trifluoromethyl-3,3,3-trifluoropropene from isobutane |
| abstract |
Isobutane is catalytically converted to 1-chloro-2-trifluoromethyl-3,3,3-trifluoropropene [(CF3)2C = CHCl] in a dehydro/chlorofluorination reaction zone by passing a mixture of anhydrous hydrogen fluoride, chlorine and the isobutane over a chromium oxide or metal fluoride dehydro/chlorofluorination catalyst. Alternatively, the isobutane 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 dehydro/chlorofluorination catalyst. |
