| titleOfInvention |
Process for the preparation of an alkylene carbonate and an alkylene glycol |
| abstract |
The present invention relates to a reaction system for producing alkylene carbonates comprising: an epoxidation zone containing an epoxidation catalyst located in an epoxidation reactor; A carboxylation zone containing a bromide-containing carboxylation catalyst located within an alkylene oxide absorber; And a reaction system comprising at least one purification zone containing a purified absorbent capable of reducing the amount of bromide-containing impurities in the feed containing recycle gas and upstream of the epoxidation zone; And a process for producing alkylene carbonates and alkylene glycols. |
