Air-free solutions of dibenzyl ketone (DBK) in mixtures of hexane and isopropanol were photolyzed under various conditions. A table shows the yields of the main photolysis products, dibenzyl and toluene, determined by chromatographic analysis on exposure to light from a xenon lamp of DBK solutions containing different concentrations of isopropanol. The isopropanol concentration increases the sum of the benzyl groups in dibenzyl, and in toluene it falls monotonically from 6.4 x 10/sup -3/ to 2.6 x 10/sup -3/M. The photolysis of DBK is completely different in mixtures of hexane with isopropanol exposed to high intensity laser pulses.
