Process for decomposition of cumene hydroperoxide

摘要

Use of a composition comprising cumene hydroperoxide, cumene, acidic catalyst for decomposition of cumene hydroperoxide, dicumyl peroxide, dimethylbenzyl alcohol, phenol, and acetone wherein the acetone is in a molar ratio to phenol of from 1.1:1 to 1.5:1 in the selective decomposition of dicumyl peroxide in a separate reactor to alpha methyl styrene, phenol and acetone. And a method for enhancing the decomposition of cumene hydroperoxide to phenol and acetone which comprises having additional water in the cumene hydroperoxide decomposition reactor.
