Manufacture of alkylate for petrochemical industry, involves alkylating mixture having preset amount of isobutene and specific alkene using ion-cluster liquid catalyst containing specific anion and cation

摘要

Mixture of isobutane and 4C alkene is alkylated using ion-cluster liquid catalyst, and alkylate is manufactured. Ion-cluster liquid catalyst contains cation consisting of hydrogen halide of amine having alkyl group or hydrogen halide of pyridine, and anion made up of anion of coordination complex obtained from two or more types of specific metallic compounds. Mixture (15) of isobutane (7) and 4C alkene is alkylated using an ion-cluster liquid as a catalyst, and alkylate is manufactured. The ion-cluster liquid catalyst contains a cation consisting of hydrogen halide of amine having alkyl group or hydrogen halide of pyridine, and an anion made up of anion of coordination complex obtained from two or more types of metallic compounds. One type of metallic compound is an aluminum metallic compound (C1) and another metallic compound (C2) is a compound of IB group, IIB group and transition metal elements of periodic table. The ratio of alkane and alkene in the mixture is greater than 1 to 1. An independent claim is included for static mixing-vessel reactor having sedimentation device (4) for carrying out sedimentation, and fractional-distillation apparatus for returning upper fractional distillation to a raw material mixing vessel.
