Abstract

Salts, originating from neutralisationof alkylates of a Friedel-Crafts reaction with anhydrous NH3, are sepd. from the alkylate after flocculation with water (pref. 10-20 wt.% wrt flocculated salts). Process is used for separting AlCl3 catalytic residues from Friedel-Crafts reaction of olefines with aromatic hydrocarbons, esp. of C2H4 or C3H6 with benzenes. Flocculated salts are easily decanted.
