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) Radi at. Phys. Chem. 43, 335] has been further studied in this work. The de pendences of G values of the final gamma radiolytic products such as H -2, 2,3-butanediol and acetaldehyde on acetone concentrations in liqui d ethanol were obtained. New information was provided that except the detected new product 2-methyl-2,3-butanedio (Zhang et al., 1994), anot her new final product isopropanol was also found and material balance between intermediates and major final products was obtained. In additi on, a ratio of rate constants k(e(s)(-) + CH3CHO)/k(e(s)(-) + CH3COCH3 ) = 0.96 was calculated by computer simulation, which is in good agree ment with the result obtained from pulse radiolysis experiments [Milin chuk and Tupikov (1989) Organic Radiation Chemistry Handbook].
