Abstract
A transalkylation process comprises passing one or more alkylbenzenes having at least two alkyl groups, together with benzene and/or a monoalkyl benzene, in the liquid phase over a silicate catalyst containing, in combined form, one or more of the metals Al, Mg and Zr and which is of natural or synthetic origin. Catalysts referred to are silicates containing SiO2 and oxides of Al, Zr, Mg, and optionally also of Ca, Na and K in combined form; oxides of hydrogen, carbon and sulphur in bound form may also be present. A catalyst containing 85-90 per cent SiO2 and 15-10 per cent Al2O3 is specified. The catalyst may contain less than 3.5 per cent of water. The reaction temperature may be 160-350 DEG C., and the pressure 10-80 atm. The process may yield a considerable amount of p-diisopropyl benzene and be substantially free from the o-isomer. The alkylbenzenes having at least two alkyl groups may be tri- or tetra-isopropyl-benzenes. Cumene may be alkylated with a mixture of propene and propane and a mixture of ortho and meta-di-isomers obtained by distillation of the reaction product transalkylated with benzene. The bottom product of the distillation consists of a mixture of para-diisopropyl benzene, and higher alkylated products which are separated and passed to the transalkylator. The reaction mixture from the transalkylator consists of benzene, which is recycled, cumene, which is recycled to the alkylation zone, diisopropyl benzenes and higher alkylated benzenes. In the examples, mixtures of tri-isopropyl benzenes and benzene; and diisopropyl benzenes and benzene, with or without triisopropyl benzenes, are transalkylated to obtain an increased proportion of p-diisopropyl benzene in the mixtures.
