The Gamma-Radiolysis of HCl-C2H4 Mixtures and Other Related Topics

Abstract

<p>The gamma-radiation induced reactions occurring in the three vapour phases systems; CH4-TiCl4, C2H4-TiCl4 and C2H4-HCl, have been studied. A solid product was obtained in the first system, which has been identified as a mixture of TiCL3 and chlorinated organic polymer. Low molecular weight chlorinated hydrocarbons were observed to form in the other two systems. The reaction taking place in the C2H4-HCl system has been shown to be a chain reaction, the chain propagator being a chlorine atom. A reaction mechanism has been devised, which gives kinetic expressions governing the rates of formation of the chlorinated products, which is in agreement with the experimental data.</p>
