Abstract: ETHYLBENZENE AND BENZENE ARE PRODUCED FROM TOLUENE BY A UNIQUE PROCESS WHICH COMPRISES FIRST COUPLING THE TOLUENE UNDER THE INFLUENCE OF HEAT, USING ELEMENTAL SULFUR. THE PRODUCTS OF THE COUPLING REACTION ARE BIBENZYL, STILBENE AND SOME SULFUR-CONTAINING COMPOUNDS. THE ENTIRE PRODUCT OF THE COUPLING REACTION IS THEN SUBJECTED TO A COMBINED HYDRODESULFURIZATION AND HYDROALKYLATION REACTION TO PRODUCE ETHYLBENZENE AND BENZENE AS THE ULTIMATE MAJOR PRODUCTS.

Abstract: ETHYLBENZENE AND BENZENE ARE PRODUCED FROM TOLUENE BY A UNIQUE PROCESS WHICH COMPRISES FIRST COUPLING THE TOLUENE IN THE PRESENCE OF A CATALYST AND IN THE VAPOR PHASE TO PRODUCE BIBENZYL AND STILBENE. THE OXIDATIVELY COUPLED PRODUCTS ARE THEN DILUTED WITH BENZENE AND CATALYTICALLY HYDRODEALKYLATED TO PRODUCE ETHYLBENZENE AND BENZENE AS THE ULTIMATE MAJOR PRODUCTS.
