Dioctanoyl peroxide was synthesized from octanoyl chloride and hydrogen peroxide in ether at low temperature, and the reaction of dioctanoyl peroxide with bromine in the presence of nitrogen gas was studied.The reaction products were 1-heptyl bromide, tetradecane, caprilic acid and heptyl caprilate. The yield of 1-heptyl bromide was low and independent to the concentration of bromine. With increase in concentration of bromine, the yield of caprilic acid decreased and tetradecane and heptyl caprilate increased. These results suggest that C7H15COO· produced by the decomposition of dioctanoyl peroxide reacts with bromine to form C7H15COOBr, which is accelerated to decompose into C7H15·, CO2 and Br2 with increase in concentration of bromine, and C7H15· reacts with another C7H15· and C7H15COO· rather than with bromine, and that undecomposed C7H15COOBr reacts with water to form caprilic acid in washing after the reaction. |
