Destruction of 1,1-dichloroethylene/air mixture under gamma-ray irradiation

Radiation-induced decomposition of 1,1-dichloroethylene(1,1-DCE)) in air was investigated in the experiment. The model gas prepared by mixing 1,1-dichloroethylene vapor with air was sealed in batch reactors and subjected to gamma irradiation. Inorganic products (CO+CO 2 ) and organic products were analyzed by means of a TOC analyzer and gas-chromatography, respectively. It was found that chloroacetyl chloride (CH 2 ClCOCl) was present as the main organic product while inorganic products (CO+CO 2 ) occurred in quantities below 10% based on relative carbon balance. Energy consumption of 1,1-DCE by using gamma-ray irradiation was compared with that by using electron beam irradiation.
