Laser-Powered Dehydrochlorination of some Polychlorohydrocarbons

The C02 laser-powered homogeneous dehydrochlorination of 1,2-dichloroethane, 1,1,1-trichloroethane, cisand trans-1,2-dichloroethane and trichloroethene sensitized by sulfur hexafluoride in argon does not exhibit features of the radical-chain reaction observed in hot vessels. No effect of propene (radical-chain reactions retarder) and chloroethane (chlorine atom scavenger) upon the reaction rate of the dehydrochlorination is interpreted by a molecular mechanism of the laser-powered process.
