Abstract
An alkyl-substituted hydrocarbon is prepared effectively under mild conditions by alkylating an alkyl 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 treating a water-containing oxide of an alkaline earth metal with at least one material selected from the group consisting of alkali metals and alkali metal hydrides in an amount of 0.5 to 3.5 equivalents per one mole of water in said oxide in an inert gas atmosphere.
