Bisphenol A can be synthesized by reacting phenol with acetone in the presence of a catalyst, comprising a montmorillonite clay having the structure: Mx/n<n+>yH2O(Al4-xMgx)(Si8)O20(OH)4 where M represents the interlamellar cation, and x, y and n are numbers, which has been rendered acidic by pretreatment with one or more acids selected from hydrogen fluoride, fluorosulphonic acids or anhydrides, and mineral acids. The reaction is carried out at a temperature of from 20 to 200 DEG C and a pressure of 0.1 to 7.0 MPa. |
