Method for continuous production of dialkyl carbonate |
| abstract |
The present invention relates to a continuous process for purifying a dialkyl carbonate / alkyl alcohol mixture in the production of dialkyl carbonate by catalyzed transesterification of a cyclic alkylene carbonate (e.g., ethylene or propylene carbonate) with alkyl alcohols. To increase the product quality of the dialkyl carbonate, the choice of operating parameters of the dialkyl carbonate purification column is crucial to reduce the formation of undesired by-products such as alkoxy alcohols and aliphatic carbonate ethers. |
