Process for the production of para-vinyl phenol by dehydrogenation of para-ethyl phenol

摘要

A process for the production of p-vinyl phenol by the dehydrogenation of p-ethyl phenol in a gaseous phase in the presence of a catalyst and a diluent wherein the dehydrogenation of p-ethyl phenol is effected with phenol and/or p-cresol being present in the reaction system in an amount of 5 to 50 wt % of the amount of p-ethyl phenol.
