Abstract: The Friedel-Crafts alkylation (cyclohexylation of phenol with cyclohexene) has been carried out over 12-tungstophosphoric acid supported on hydrous zirconia under mild conditions. The catalyst shows high activity and selectivity for 2-cyclohexyl phenol, an important product used as intermediate in dyestuff preparation as well as in preparation of 2- phenyl phenol which is used as disinfectant and fungicide. In addition, the catalyst can be ...
