PROCEDURE FOR REMOVING CATALYTIC METALS AND PROMOTER METALS FROM CARBONILLATION PROCESS |
| abstract |
A process for the selective removal of Group VIII carbonylation catalyst metals and / or promoter metals from a liquid composition comprising a carbonylation product, Group VIII carbonylation catalyst metals and / or promoter metals, corrosive metals and optionally alkali and alkaline earth metals. The process comprises contacting the liquid composition with chelating resins having thiourea functional groups. The process is suitable for treating currents obtained in the production of carbonylation acids and / or carboxylic anhydrides. |
