Abstract
A process for purifying and separating active rhodium catalyst from a hydroformylation process stream containing inactive rhodium catalyst, which comprises: contacting at least a portion of the process steam with an acidic ion exchange resin containing a silica backbone and a functional acidic group adhered thereon for binding impurities and active catalyst complex to the resin and generating a purified hydroformylation process stream, in which the functional acidic group is selected from aromatic sulfonic acids, aliphatic sulfonic acids, aromatic carboxylic acids and aliphatic carboxylic acids.
