PURPOSE:To use titanium oxide or a combined catalyst of the titanium oxide with manganese oxide, iron oxide, etc. capable of maintaining a high activity and selectivity stably for a long term in dehydrogenating an ethylphenol to give the corresponding ethenylphenol. CONSTITUTION:An ethylphenol is dehydrogenated to give the corresponding ethenylphenol. In the process, a catalyst containing titanium oxide or the titanium oxide and a metallic oxide, e.g. mangenese oxide, iron oxide, copper oxide, zinc oxide, zirconium oxide, molybdenum oxide, tin oxide, antimony oxide, cerium oxide, lithium oxide, magnesium oxide, calcium oxide, and barium oxide, in combination is used. |
