CA 2609300
A process is provided for producing an enriched carboxylic acid compositions produced by contacting composition comprising a carboxylic acid with an enrichment feed in an enrichment zone to form an enriched carboxylic acid composition. This invention also relates to a process and the resulting compositions for removing catalyst from a carboxylic acid composition to produce a post catalyst removal composition.
La présente invention concerne un procédé de production de compositions d'acide carboxylique enrichies dans lequel on met en contact la composition comprenant un acide carboxylique avec une charge d'enrichissement dans une zone d'enrichissement pour former une composition d'acide carboxylique enrichie. Cette invention porte également sur un procédé et sur les compositions résultantes qui permettent d'éliminer un catalyseur d'une composition d'acide carboxylique pour produire une composition débarrassée du catalyseur.
