PROCESS FOR THE PREPARATION OF AN ALKYLENE CARBONATE AND AN ALKYLENE GLYCOL |
摘要 |
The invention provides a reaction system for the production of an alkylene carbonate comprising: an epoxidation zone containing an epoxidation catalyst located within an epoxidation reactor; a carboxylation zone containing an bromide-containing carboxylation catalyst located within an alkylene oxide absorber; and one or more purification zones containing a purification absorbent capable of reducing the quantity of bromide-containing impurities in a feed comprising a recycle gas, which purification zones are located upstream from the epoxidation zone; and a process for the production of an alkylene carbonate and an alkylene glycol.
