A method for the manufacture of a sulfonated phenol for use as a cumene hydroperoxide decomposition catalyst can comprise: combining phenol and a sulfonating agent at a first temperature that is 1&#xb0; C. to 15&#xb0; C. higher than a melting temperature of the phenol, to form a reaction mixture at the first temperature; reducing the first temperature of the reaction mixture to a second temperature that is 10 to 40&#xb0; C. lower than the first temperature; and forming the sulfonated phenol at the second temperature.

Optimization of O-sulfonated phenol production for cumene hydroperoxide cleavage

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.
