PROCESS FOR ALKYLATING AKKYLAROMATIC HYDROCARBONS

摘要

An alkyl-substituted hydrocarbon is prepared by alkylating an alkylaromatic hydrocarbon having at least one hydrogen atom on an alpha-carbon in a side chain with an olefin in the presence of a solid base which is obtainable by treating an alumina with at least one compound of an alkaline earth metal at a temperature of from 200 to 800 DEG C and then with at least one compound selected from the group consisting of alkali metals and alkali metal hydride in an inert gas at a temperature of from 200 to 800 DEG C.
