  • Process for removing organic oxygen-containing impurities from an organic composition in the presence of steam
    Patent number: 4104318
    Abstract: The amount of oxygen-containing impurities in an organic composition is reduced at an elevated temperature in the presence of steam using a catalyst comprising a Group VIb or Group VIII metal oxide or phosphate. For example, the amount of oxygen-containing organic impurities in a crude stilbene product obtained by the oxidative dehydrocoupling of toluene is catalytically reduced at high temperatures in the presence of steam and an iron oxide catalyst and the resulting stilbene product is reacted with ethylene to form styrene.
