ABSTRACT:
The amount of oxygen-containing impurities in an organic composition is reduced at an elevated temperature by contact with a supported metal oxide. For example, the amount of oxygen-containing organic impurities in a crude stilbene product obtained by oxidatively dehydrocoupling toluene using a solid oxidant is decreased by contact with zinc oxide supported on alumina at an elevated temperature and the resulting purified stilbene product is reacted with ethylene to form styrene.
