✦ Synopsis

The photosensitized chain reaction of 1.2-dichloroethane induced by a cw co laser produced vinyl chloride with high purity. The initiation of the chain reaction is strictly dependent on the irradiated laser frequency. Kinetics of the chain reaction has been studied on the basis of the effects of laser frequency, laser incident power and the pressure of sensitizer on reaction rate. Arrhenius plot shows an activation energy of 21.8 kcal per mole. Generating the active centers by infrared laser can allow the reactions of chain propagation with low activation energy to proceed at a lower temperature, which is of significance in cutting down the energy expenditure and formation of by-products in the process.
