Catalytic Dehydrofluorination of CF3CH3(HFC143a) Into CF2CH2(HFC1132a)

Applied Catalysis B: Environmental, 1998
Abstract The catalytic dehydrofluorination of CF 3 CH 3 was studied over various metal phosphate catalysts in a fixed-bed reactor. The Mg 2 P 2 O 7 catalyst exhibited the moderate activity and high selectivity of CF 2 CH 2 , and it is the most suitable catalyst for the dehydrofluorination of CF 3 CH 3 .

The synthesis and dehydrofluorination of some polyfluoroalkanes

Journal of Fluorine Chemistry, 1972
Abstract trans -1,2-Bis-(heptafluoro-n-propyl)- and trans -1,2-bis-(pentadecafluoro-n-heptyl)-ethylene were made from copper perfluoroalkyls. Fluorination over CoF 3 afforded perfluoro- and polyfluoro-n-octanes and -n-hexadecanes. Dehydrofluorination of 4 H -heptadeca- and 4 H ,5 H -hexadecafluoro-n-octane are much slower than those of undeca- and
