A process for the production of a carbonylation product containing a carboxylic acid and/or an este r thereof |
摘要 |
<p>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 vapourisation with or without the addition of heat to produce a vapour-fraction and a liquid fraction, the vapour fraction comprises carbonylation product and the liquid fraction has a water concentration of at least 0.5% by weight to stabilise the iridium catalyst. <IMAGE></p> |
