RADIATION CHEMISTRY OF ISOPROPYL COMPOUNDS (thesis)
Purified, degassed samples of eight organic liquids, isopropyl chloride, isopropyl alcohol, isopropyl benzene, isobutyronitrile, isobutyric acid, isovaleric acid, methyl isobutyl ketone, and isopropyl acetate, were irradiated with 48-Mev helium ions and with gamma rays from a Co/sup 60/ source. The volatile radiolysis products were separated and annlyzed. Formation of these products is explained by free-radical reactions and by molecular rearrangements of the type i-C/sub 3/H/sub 7/X = HX + C/sub 3/H/sub 6/. The differences in respective product yields between the two types of radiation were in accord with the proposed decomposition patterns. Products considered to be formed by radical- radical reactions were found in larger yield in the more densely ionizing helium- ion irradiations; Co/sup 60/ irradiations formed larger amounts of products considered to result from radical-molecule reactions. Molecular rearrangement to form HX plus propylene occurred in these radiolyses. For several of the compounds studied it was a major source of radiolytic product. The extent of rearrangement in any given compound depends on the electronic nature of the molecule and on the mechanism by which the rearrangement occur s. (auth)
