Process for producing a monoalkenylaromatic hydrocarbon compound

摘要

A solid material is obtained by calcining a mixture of a carbonate or a hydroxide of an alkaline earth metal and a potassium compound, adding an alkali metal to the obtained calcined product under an atmosphere of an inert gas, and subsequently heat treating the obtained mixture at a temperature which is the same as or higher than the melting point of the alkali metal. A process for producing a monoalkenylaromatic hydrocarbon which comprises alkenylating a side chain of an aromatic hydrocarbon compound having at least one hydrogen atom at the alpha -position of the side chain with a conjugated diene having 4 or 5 carbon atoms in the presence of a catalyst comprising the obtained solid material is disclosed. In accordance with the above process, a monoalkenenyl aromatic hydrocarbon can be produced safely at a low cost, and the process has a remarkable industrial advantage.
