Abstract
A process comprising: (a) providing a slurry comprising a solid phase and a liquid phase, wherein said solid and liquid phases contain terephthalic acid, respectively (b) subjecting at least a portion of said terephthalic acid contained in said solid phase to oxidation treatment in the presence of a catalyst to thereby produce oxidation-treated terephthalic acid; and (c) subjecting at least a portion of said terephthalic acid contained in said liquid phase to hydrogenation treatment in the presence of a catalyst to thereby produce hydrogenation-treated terephthalic acid.
