A method for producing phenol and acetone in a multi-stage process at an elevated temperature from a cumene hydroperoxide mixture comprising cumene, the method comprising the steps of a) reacting the cumene hydroperoxide mixture with a 2-hydroxybenzenesulfonic acid catalyst having a concentration of 0.1 to 1 mmol/L acid catalyst to form a second mixture comprising phenol, acetone and dicumyl peroxide in a first stage and decomposing the second mixture in a second stage to produce a third mixture comprising phenol and acetone.

Method for producing phenol and acetone

A method for producing phenol and acetone in a multi-stage process at an elevated temperature from a cumene hydroperoxide mixture comprising cumene, comprises the steps of: wherein an amount of phenol approximately equal to the amount of distilled from the cumene hydroperoxide mixture is added to the cumene hydroperoxide mixture before the reacting step b). The amount of hydroxyacetone is reduced, thereby, improving the quality of commercial-grade phenol and the products made from the phenol.
