Preparation of 4,4,4-trifluoro-2-methyl-1-butene by the dehydrochlorination of 3-chloro-1,1,1-trifluoro-3-methylbutane, the preparation of 1,2-epoxy-4,4,4-trifluoro-2-methylbutane and the polymerization thereof

摘要

The partially fluorinated alkene 4,4,4-trifluoro-2-methyl-1- butene is produced by the selective dehydrochlorination of 3-chloro-1,1,1- trifluoro- 3-methylbutane in the presence of a suitable base at elevated temperatures. The alkene is converted to 1,2-epoxy-4,4,4-trifluoro-2- methylbutane which is polymerizable in the presence of an aluminum coordination catalyst. A copolymer can be made with epichlorohydrin.
