Abstract

In order to clarify the effect of carbon tetrachloride on the radiolysis of di(2-ethylhexyl)phosphoric acid(DEHPA), DEHPA diluted with carbon tetrachloride was exposed to60Co γ-rays in the presence or absence of aqueous solution and the yields of degradation products of DEHPA and hydrogen chloride were determined. Radiolysis of DEHPA is enhanced by carbon tetrachloride, most intensively in the stirred system of DEHPA−CCl4 and an aqueous solution. Carbon tetrachloride also corroded stainless steel immersed in it during γ-irradiation owing to the formation of hydrogen chloride. Yield of hydrogen chloride increased in the presence of the aqueous solution, most effectively upon stirring, and corrosion became significant.
