Preparation of diisobutyryl peroxide by reaction extraction coupling enhanced based on microchannel reactors
The influence of diisobutyryl peroxide reaction system,reaction temperature,alkali concentration and other factors were investigated.Under the protection of organic solvents at a reaction temperature of 0℃and alkali concentration of 20%,the yield of diisobutyl peroxide reached 75.6%.Furthermore,the mecha-nism of the reaction process was explored.It suggested that organic solvents as extractants significantly in-hibit the hydrolysis of raw materials and OH-ions regulated the morphology of peroxides in the solution.And the reaction mechanism suggested the high yield was due to the dual effects of organic solvents on the slow-release effect of isobutyryl chloride and the protection of diisobutyryl peroxide in extraction were also investi-gated.
