PROCESS FOR THE RECOVERY OF A CARBONYLATION PRODUCT |
| 摘要 |
<p>The invention relates to the recovery of a carbonylation product from a liquid carbonylation reaction composition that contains carbonylation product and free or combined iridium carbonylation catalyst. The process comprises subjecting the liquid carbonylation reaction composition to a vaporisation with or without the addition of heat to produce a vapour fraction comprising carbonylation product and a liquid fraction comprising iridium carbonylation catalyst, and separating the liquid and vapour fractions. During the process there is maintained in the liquid fraction a concentration of water of at least 0.5% by weight.</p> |
