ABSTRACT:
This invention relates to an improved method for the production of high purity dicumyl peroxide. As produced, dicumyl peroxide contains many impurities which must be removed. Generally, our invention comprises flash distilling crude dicumyl peroxide, separating and discarding the distillate and allowing the residual product to crystallize. The supernatant liquid from the crystallized dicumyl peroxide is then fed into the next batch of crude dicumyl peroxide to be distilled. In this manner high yields are obtained along with a very rapid distillation time. Because the supernatant liquid from each crystallization is fed back into the process, the dicumyl peroxide normally left in the supernatant is recovered in the subsequent steps.
