Process for the recovery of a carbonylation product |
| 摘要 |
A process for the recovery of a carbonylation product from a liquid reaction composition of an iridium-catalysed carbonylation reaction of a carbonylatable reactant comprises subjecting the composition to a vaporization with or without the addition of heat to produce a vapor-fraction and a liquid fraction, the vapor fraction comprises carbonylation product and the liquid fraction has a water concentration of at least 0.5% by weight to stabilize the iridium catalyst.
