Abstract:
1. A process to produce a carboxylic acid composition, said process comprising: (a) oxidizing in an primary oxidation zone an oxidizable compound in a oxidizable raw material stream in the presence of a solvent stream, an oxidizing gas stream, and a catalyst system, wherein said an oxidizable raw material stream comprises at least one compound selected from the group consisting of 5-(hydroxymethyl)furfural (5-HMF), 5-HMF esters (5-R(CO)OCH (b) routing said carboxylic acid composition to a cooling zone; (c) routing cooled carboxylic acid composition to a solid-liquid separation zone generating a mother liquor stream and wet carboxylic acid composition; (d) routing the wet carboxylic acid composition to a drying zone to produce a dry crude carboxylic acid composition.
