Photolysis of Mixtures of Diethyl Ketone and Carbon Tetrachloride

Abstract

The photolysis of mixtures of diethyl ketone and carbon tetrachloride has been investigated at room temperature. The following reaction products were observed: CO, C₂H₆, C₂H₄, C₄H₁₀, CHCl₃, C₂H₅CCl₃, C₂Cl₆, C₂H₅ (CH₃) CHCOC₂H₅, and CH₃ (CCl₃) CHCOC₂H₅. Primary radicals produced by photolysis of diethyl ketone and carbon tetrachloride are C₂H₅, CCl₃, and Cl. Chlorine atoms react with diethyl ketone to form HCl and CH₃CHCOC₂H₅ radicals. Disproportionation and recombination reactions involving CCl₃, C₂H₅, and CH₃CHCOC₂H₅ radicals are largely influential in the formation of many of the products. The ratios of disproportionation over recombination for CCl₃ and C₂H₅ radicals and for CCl₃ and CH₃CHCOC₂H₅ radicals were obtained together with various ratios of other rate constants.
