ABSTRACT:
A method is disclosed for the synthesis of phenol and acetone by acid-catalyzed decomposition over a catalyst comprising an acidic montmorillonite silica alumina clay, modified with a compound from the group consisting of a heteropoly acid, or the inorganic salt of zirconium, titanium and aluminum. The method allows for a 6-fold improvement in rate using heteropoly acid modified montmorillonite clays and a six to 10-food improvement is observed using zirconium or titanium, respectively.
