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 heating and reacting an alumina with at least one carbonate of an alkali metal and at least one material selected from the group consisting of potassium and alkali metal hydrides at a temperature of from 180.degree. to 800.degree. C. in an inert gas atmosphere, as a catalyst.
