THE PHOTOLYSIS OF MIXTURES OF ACETONE AND SOME HALOGENATED HYDROCARBONS

Abstract

The composition of the products of photolysis of acetone in the presence of methyl chloride, methyl bromide, methylene chloride, and methylene bromide has been determined. These reactions are attended by complications not found with the photolysis of acetone–hydrocarbon mixtures. Failure to take into account reactions resulting from the formation of halogen hydrides and to allow for the presence of ethylene invalidates the values obtained by Raal and Steacie for the activation energy for hydrogen abstraction by methyl radicals from some halogenated hydrocarbons.
