ENVIRONMENT-FRIENDLY POST-TREATMENT METHOD FOR FRIEDEL-CRAFTS REACTION

摘要

Disclosed is an environment-friendly post-treatment method for Friedel-Crafts reaction, which mainly comprises the following steps: 1. Alkylation or acylation reaction on aromatic ring is facilitated by using Lewis acid. 2. The reaction solution is adsorbed by non-metallic mineral adsorbent over a suitable period of time. 3. The adsorbent (lewis acid catalyst is adsorbed in it) and the reaction solution are separated. 4. The refined product is obtained by recovering the solvent from the reaction solution. The method of the invention can effectively remove the Lewis acid in the Friedel-Crafts reaction by using the non-metallic mineral adsorbent. The method is simple, practical, low-cost, environment-friendly, and easy for industrialization.
