摘要： Benzene and n-butene (1-, cis- and/or trans-) are reacted at a temperature of 20 to 70 DEG C in the presence of a complex catalyst which is a homogeneous liquid of aluminum chloride, hydrogen chloride and an aromatic hydrocarbon, in amount of 0.3 to 5 wt% of the AlCl3 to the benzene (prepared by stirring for 1/3 - 3 hours); the reaction mixture is separated into fractions containing mainly the desired product sec-butylbenzene with not more than 1% of by-product isobutylbenzene; heavy materials; and (which are recycled) benzene, and dibutyl- and tributylbenzenes. The catalyst can be separated, recovered and recycled. The reaction can be continuous or batchwise. The product sec-butylbenzene can be utilised for production of phenol.
