A process to produce an enriched composition, said process comprising: (a) oxidizing an aromatic feedstock in a primary oxidation zone to form a crude carboxylic acid composition, wherein said crude carboxylic acid composition comprises terephthalic acid; (b) optionally subjecting said crude carboxylic acid composition to a liquid displacement zone to form a slurry composition; (c) crystallizing said slurry composition or said crude carboxylic acid composition in a crystallization zone to form a crystallized slurry composition; (d) cooling and optionally enriching said crystallized slurry composition in a cooling zone to form a cooled carboxylic acid composition; (e) subjecting said cooled carboxylic acid composition, and a wash feed to a catalyst removal zone to form a post catalyst removal composition, a wash liquor, a catalyst rich liquor; (f) subjecting said post catalyst removal composition to an enrichment feed in an enrichment zone to form said enriched composition wherein said enrichment feed comprises at least one compound selected from the group consisting of isophthalic acid, phthalic acid, benzene-tricarboxylic acid isomers, benzoic acid, hydroxybenzoic acid isomers, hydroxymethylbenzoic acid isomers, dicarboxybiphenyl isomers, dicarboxystilbene isomers, tricarboxybiphenyl isomers, tricarboxybenzophenone isomers, dicarboxybenzophenone isomers, dicarboxybenzil isomers, form-acet-hydroxybenzoic acid isomers, acet-hydroxymethylbenzoic acid isomers, a-bromo-toluic acid isomers, bromo-benzoic acid, bromo-acetic acid, tolualdehyde isomers, benzyl alcohol isomers, methyl benzyl alcohol isomers, and phthaldehyde isomers.
