Abstract
An alkyl-substituted hydrocarbon is prepared 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 reacting an alumina with an alkali metal carbonate and/or aluminate and an alkali metal amd/or its hydride in an inert gas atmosphere at a temperature of 180.degree. to 800.degree. C. as a catalyst.
