Abstract
The kinetics of the thermally and radiation initiated chain reaction between trichloroethylene and cyclopentane to produce 1,1‐dichlorovinylcyclopentane and hydrogen chloride have been investigated in the temperature range 250–360°C at high pressure in the gas phase. The rate governing step in the chain is (k3 = 3.3 × 109 exp −(4800/RT) cc mole−1 sec −1). The rate of the unimolecular decomposition of trichloroethylene is 1.4 × 1014 exp −(61,200/RT) sec−1.
