Abstract

The thermal decomposition of 1,1,1‐trifluoro‐2‐chloroethane has been investigated in the single‐pulse shock tube between 1120° and 1300deg;K at total reflected shock pressures from ∼2610 to 3350 torr. Under these conditions, the major reaction is the α,α‐elimination of hydrogen chloride,

with

The decomposition also involves the slower α,β‐elimination of hydrogen fluoride,

with the first‐order rate constant given by

At temperatures above 1270°K, two additional minor products were observed. These were identified as CF~2~CFCl and CF~3~CHCl~2~ and suggest CCl rupture as a third reaction channel leading to complicated kinetics.
