Abstract:
The present disclosure relates to methods for separating and purifying a long chain diacid from other long chain diacids, monocarboxylic acids, hydroxyl acids or alkanes by simulated or actual moving bed chromatography.

Claim (Index 24):
The method of  claim 1 , comprising:\n (a) introducing a feed stream comprising a solution comprising dodecanedioic acid, 12-hydroxydecanoic acid and lauric acid, into a first zone of moving bed chromatography apparatus (MBCA); (b) collecting a raffinate stream or an extract stream from the first zone of the MBCA, the raffinate stream comprising the dodecanedioic acid and 12-hydroxydecanoic acid, and the extract stream comprising the dodecanedioic acid and lauric acid; (c) introducing the raffinate stream or the extract stream into a second zone of the MBCA; (d) collecting a second raffinate stream or a second extract stream from the second zone of the MBCA, the raffinate stream comprising the dodecanedioic acid and 12-hydroxydecanoic acid, and the extract stream comprising the dodecanedioic acid and lauric acid; (e) introducing the second raffinate stream or the second extract stream into the first zone or the second zone of the MBCA; (f) optionally repeating steps (d) and (e) until a desired degree of separation is achieved; and (g) collecting a final raffinate stream or a final extract stream from a zone of the MBCA, the final raffinate stream or the extract stream comprising the dodecanedioic acid, thereby separating the dodecanedioic acid from the 12-hydroxydecanoic acid and lauric acid.
