PROCESS FOR PREPARING ALKYL-SUBSTITUTED AROMATIC HYDROCARBONS
摘要
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 an alumina, an alkali metal hydroxide and an alkali metal hydride or an alumina containing at least 1.3 % by weight of water and an alkali metal hydride in an inert gas atmosphere at a temperature of 200 to 800 DEG C as a catalyst.
