Description

Studies have been carried out on the amount of hydrogen chloride formed by the radiolysis of some chloroalkanes and the energy absorbed in the solutions. The samples were prepared by dissolving p-dimethylaminoazobenzene as a dye (1.0×10-4 mol/dm3) in the chloroalkanes, and were irradiated at a dose of 2500 R at 20°C. The amount of hydrogen chloride formed in the irradiated sample was determined spectrophotometrically. The absorbed dose of the irradiated sample was calculated from the equation, DM=8.77×10-3× (Z/A) M/ (Z/A) A×RA (Gy) . G (HCl) values for hydrogen chloride formed in the solutions of chloroform, 1, 2, 3-trichloropropane and 1, 2-dichloroethane were 10.2, 8.5 and 5.7, respectively. On the other hand, the dielectric constants of the above chloroalkanes measured were 4.3, 7.8 and 10.7, respectively, being in inverse prorortion to G (HCl) .<BR>These results seem to suggest that the formation of hydrogen chloride and its reaction with the dye in the irradiated solution are influenced by the dielectric constant of chloroalkane.
