Radiolytic Processes in Boiling Acetone

The composition and yields of the radiolysis products of boiling acetone change significantly compared to those at room temperature. Boiling in combination with a high dose rate and radiolytic acidification leads to the appearance of enol products (isopropenyl acetate, 2-methoxypropene, and vinyl acetate) and other products uncharacteristic of gamma radiolysis at lower temperatures (allene, tert-butanol, and esters). The enolization processes are manifested in an increase in the yields of hydrogen, acetic acid, alkoxy derivatives, and polymers. The formation of enol products in primary ionic processes and in secondary processes involving vinyloxy and propene-2-oxy radicals is considered. The role of the thermal decomposition of radicals in decreasing the yields of a number of products of radical recombination is noted.
