The stable products of radiolysis of 1,2-dichloroethane (12DCE) g-irradiated in an oxygen-free atmosphere were investigated. The pure products of radiolysis were separated by preparative gas chromatography and identified by 1H, 13C NMR and mass spectroscopy as well as quantitative gas chromatography. In the gas phase we have obtained H2 and HCl; in the liquid phase: chloroethane, 1,1-dichloroethane, 1,1,2-trichloroethane, 1,2,4-trichlorobuthane and 1,2,3,4-tetrachlorobutanes (dl- and meso-: [2R,3R] or [2S,3S] and [2R,3S]-isomers). On the basis of the results obtained a preliminary scheme for the formation of the stable products is proposed.
