THE $gamma$-RADIOLYSIS OF SOLUTIONS OF HYDROGEN CHLORIDE IN CYCLOHEXANE

Solutions of hydrogen chloride in cyclohexane, when irradiated with gamma rays, give hydrogen with G = 6.05 compared with G = 4.85 from cyclohexane alone. When iodme is presChem., 65: 953-6(June 1961). ent (4 x 10/sup -//sup 4/ M) the yield for iodine removal is G = 7.0 atoms removed per 100 ev, compared with G = 4.8 in the absence of hydrogen chloride. Solutions of hydrogen chloride also differ from pure cyclohexane in that they become yellow on irradiation, and give cyclohexyl chloride and a highly unsaturated material of high molecular weight. No cyclohexene is produced. Many of these results can also be obtained with light instead of gamma rays. It is concluded that excited molecules must be responsible for the effects. (auth)
