Patent name: HIGH SELECTIVE METHOD OF PRODUCING CUMENE HYDROPEROXIDE, PHENOL AND ACETONE IN AN OXIDATION BY-PRODUCT CONVERSION PROCESS

Patent Number: US 6,943,270

September 13, 2005

A cumene process of producing phenol and acetone comprises the joint oxidation of aldehydes and dimethylbenzene alcohol by aqueous hydrogen peroxide solutions in presence of 16 wt % to 94 wt % of cumene hydroperoxide by contacting of mutually insoluble phases of the organic products from a cumene oxidation stage and hydrogen peroxide containing water with optional addition of acidic catalysts in a conversion reactor for the purpose of conversion of aldehydes into organic acids and dimethylbenzene alcohol into cumene hydroperoxide and therefore significantly simplifying the process of fractionation of organic conversion products into high quality product phenol and product acetone.
