ABSTRACT:
An alkyl-substituted hydrocarbon is prepared by alkylating an aromatic hydrocarbon having at least one hydrogen atom at an alpha-position in a side chain with an olefin in the presence of a solid base which is obtainable by heating an alumina, an alkali metal hydroxide and an alkali metal or an alumina containing at least 1.3% by weight of water and an alkali metal in an inert gas atmosphere at a specific temperature as a catalyst.
