Selecting ethanol as a model organic solvent in radiation chemistry .1. Radiolysis of acetone-ethanol system

Radiolysis of acetone-ethanol solution [Zhang, Wu and Zhou (1994) Radiat. Phys. Chem. 43, 335] has been further studied in this work. The dependences of G values of the final gamma radiolytic products such as H-2, 2,3-butanediol and acetaldehyde on acetone concentrations in liquid ethanol were obtained. New information was provided that except the detected new product 2-methyl-2,3-butanedio (Zhang et al., 1994), another new final product isopropanol was also found and material balance between intermediates and major final products was obtained. In addition, a ratio of rate constants k(e(s)(-) + CH3CHO)/k(e(s)(-) + CH3COCH3) = 0.96 was calculated by computer simulation, which is in good agreement with the result obtained from pulse radiolysis experiments [Milinchuk and Tupikov (1989) Organic Radiation Chemistry Handbook].Chemistry, PhysicalNuclear Science & TechnologyPhysics, Atomic, Molecular & ChemicalSCI(E)9ARTICLE4555-5584
