In a process for forming (1-phenylethyl) hydroquinone comprising reacting styrene and hydroquinone, the improvement comprising conducting the reaction in the presence of a zeolite molecular sieve.
In a method of forming (1-phenylethyl) hydroquinone comprising reacting styrene and hydroquinone to form a reaction product containing monosubstituted (1-phenylethyl) hydroquinone, the improvement comprising conducting the reaction in the presence of a zeolite molecular sieve so as to form substantially all monosubstituted (1-phenylethyl) hydroquinone, said zeolite being a pellet of an ammonium exchanged crystalline sodium aluminosilicate having a low level of sodium and being bonded with an acid washed inorganic oxide.
