IODINE CYANIDE B S A SCAVENGER IN THE RADIOLYSIS OF LIQUID BENZENE' BY GORDON HUGHES Department of Inorganic and Physical Chemistry, The University, Liverpool, England Received June 6 , 1961

Deconiposition yields in the radiolysis of benzene have been measured using ICN as scavenger. The results are not readily explained in terms only of free radical reactions and indicate that processes of charge (or energy) transfer are taking place.

The radiation chemistry of liquid benzene has been widely i n ~ e s t i g a t e d . ~ -The ~ yield of hydrogen gas evolvedZand the radical yield as measured by conventional scavengers e.g., DPPHj5 12'jare both low in comparison with the corresponding yields for alkanes. Because of this, benzene has been regarded as fairly inert to radiation damage. Scavenger studies have, in the main, been confined to low concentrations Le.,
