Abstract:
Disclosed is an oxidation process to produce a crude carboxylic acid product carboxylic acid product. The process comprises oxidizing a feed stream comprising at least one oxidizable compound to generate a crude carboxylic acid slurry comprising furan-2,5-dicarboxylic acid (FDCA) and compositions thereof. Also disclosed is a process to produce a dry purified carboxylic acid product by utilizing various purification methods on the crude carboxylic acid.

Claim (Index 1):
A process to produce a raffinate stream in a method for making a carboxylic acid, said process comprising:\n (i) oxidizing in an oxidation zone an oxidizable raw material stream comprising 5-(hydroxymethyl) furfural (5-HMF) in the presence of an oxidation solvent stream comprising a saturated organic acid having from 2-4 carbon atoms and a catalyst at a temperature of 100\u00b0 C. to 220\u00b0 C. to produce a crude carboxylic acid slurry; wherein said oxidation zone comprises at least one oxidation reactor; wherein said crude carboxylic acid slurry comprises furandicarboxylic acid; wherein said catalyst comprises cobalt, manganese and bromine; and wherein the yield of furandicarboxylic acid is greater than 60%; (ii) routing said crude carboxylic acid slurry to a solid liquid separation zone to produce a mother liquor stream comprising said catalyst and impurities; (iii) routing at least a portion of said mother liquor stream to a mother liquor purge zone to produce a raffinate stream comprising catalyst solvent and oxidation catalyst; wherein at least a portion of said oxidation catalyst and/or catalyst solvent can be recycled to the oxidation zone; wherein said oxidizable raw material stream comprises greater than 20% by weight of 5-HMF.
