PURIFICATION OF ALCOHOLS PRIOR TO THEIR USE IN THE PRESENCE OF AN ACID CATALYST
摘要
Process for the purification of an alcohol in the course of a process comprising : (1) providing a reaction zone (C) comprising an acid type catalyst; (2) providing a reaction zone (B) comprising an acid adsorbent material; (3) providing an alcohol stream comprising impurities; (4) introducing the alcohol stream of (3) into the reaction zone (B) and bringing said stream into contact with the acid adsorbent material at conditions effective to reduce the amount of impurities having an adverse effect on the acid type catalyst of the reaction zone (C); (5) recovering from step (4) an alcohol stream and introducing it into the reaction zone (C); (6) optionally introducing one or more reactants (R) into the reaction zone (C); (7) operating said reaction zone (C) at conditions effective to recover a valuable effluent.
