ABSTRACT:
A method of alkylating a side chain of alkyl-substituted aromatic hydrocarbons. The method involves the steps of loading an alkali metal on a thermally treated hydrotalcite carrier represented by formula (I) by an impregnation method using the alkali metal dissolved in liquid ammonia, thermally treating the alkali metal loaded hydrotalcite carrier under vacuum to prepare a catalyst, then reacting an alkyl-substituted aromatic hydrocarbon with an aliphatic monoolefin using the catalyst under an atmosphere substantially free of oxygen, water and carbon dioxide gas to alkylate a side chain of the alkyl-substituted aromatic hydrocarbon:
