Procedure

alkylation of benzene with isopropanol, or a blend of isopropanol and propylene, to give cumene and water, comprising effecting said alkylation reaction completely in gaseous phase and in the presence of a catalytic system containing a zeolite belonging to the MTW family; 2) oxidation of the cumene thus obtained to cumyl hydroperoxide; 3) treatment of the cumyl hydroperoxide with acids in order to obtain a mixture of phenol and acetone; 4) hydrogenation of the acetone to isopropanol which is recycled to step (1).
