<p>PURPOSE:To obtain the subject compound under mild condition in high efficiency with small amount of catalyst by using a solid base heat-treated at a specific temperature as a catalyst and alkylating the alpha-site of an aromatic hydrocarbon having H on the alpha-site of a side chain with an olefin. CONSTITUTION:The objective compound useful as an intermediate raw material for fine chemicals such as pharmaceuticals and cosmetics can be produced by reacting (A) an aromatic hydrocarbon having H on the alpha-site of a side chain (e. g., cumene) with (B) an olefin (e.g., ethylene) at 0-300 deg.C under a pressure of atmospheric pressure200kg/cm<2> for 0.5-50hr at a feeding rate of 0.1-600hr<-1> in the presence of (C) a solid base catalyst having high activity, fluidity and handleability and little danger of ignition even in contact with air and produced by heating alumina, an alkali metal carbonate and/or aluminate and an alkali metal in an inert gas atmosphere at 180-800 deg.C for 10-300min. Not only the handling of the catalyst but also the post-treatment of the reaction product are extremely easy.</p> |
