PRODUCTION OF TERT-AMYLBENZENE

摘要

PURPOSE:In reacting isoamylene with benzene, to obtain the titled compound useful as a raw material for synthesis or a solvent in high purity and advantageously, by introducing hydrogen chloride to a reaction solution in the presence of a catalyst consisting of aluminum chloride and an aliphatic nitro compound. CONSTITUTION:Isoamylene is reacted with benzene at 0-50 deg.C, preferably 10-40 deg.C by the use of aluminum chloride and an aliphatic nitro compound in a molar ratio of 0.7-1.3 as a catalyst by introducing preferably >=0.3mol based on isoamylene of hydrogen chloride to a reaction solution to give the aimed compound. Nitromethane is preferable as the aliphatic nitro compound as the catalyst and the amount of the catalyst used is preferably 0.1-10wt% based on benzene. The amount of raw material isoamylene is preferably 1.0-0.5mol based on 1mol benzene.
