Verfahren zur Reaktivierung von Aluminiumtrichlorid-Katalysatoren

摘要

The liquid aluminium trichloride-hydrocarbon complex formed from a catalytic process is reactivated by instantaneously vaporizing it under conditions such as to form no more than 25 wt. percent of normally gaseous products, e.g., at atmospheric pressure and 300 DEG to 500 DEG C, and the vaporized products are condensed and the normally liquid catalytic products are recovered. The complex can be used for catalysing the alkylation of benzene with propylene tetramer.
