Method for production of phenol/acetone from cumene hydroperoxide.

摘要

Cumene hydroperoxide can be decomposed into phenol and acetone under mild conditions (a temperature of 20 to 150 DEG C and a pressure of 0.1 to 7 MPa) by means of a heterogeneous catalyst selected from: a heteropoly acid on an inert support, an ion exchange resin with a sulfonic acid functionality, an acidic smectite clay, a fluorine-containing acid on an inert support, and montmorillonite clay modified by a heteropoly acid or by titanium, zirconium or aluminium.
