CATALYTIC PROCESS FOR PRODUCING AN ALKYLENE GLYCOL WITH REACTOR-OUTPUT RECYCLE

摘要

A process for the production of an alkylene glycol comprising:a feed mixture containing a respective alkylene oxide and water is introduced to at least one inlet of a reactor containing a fixed bed of a solid catalyst based on an anion exchange resin, anda reactor output mixture containing an alkylene glycol and unreacted feed mixture is removed from at least one outlet of the reactor,a characterised in that at least a part of the reactor output mixture is recycled to at least one inlet of the same reactor.
