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 1):
A method for separating a C6- to C18-carbon diacid from at least one impurity in a solution, comprising:\n (a) introducing a feed stream comprising a solution comprising at least one 6- to 18-carbon diacid and at least one impurity, the at least one impurity comprising a component more polar than the diacid, a component less polar than the diacid, or both, into a first zone of moving bed chromatography apparatus (MBCA) having one or more zones; (b) collecting a raffinate stream or an extract stream from the first zone of the MBCA, the raffinate stream comprising the diacid and one or more components more polar than the diacid, and the extract stream comprising the diacid and one or more components less polar than the diacid; (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 diacid and components more polar than the diacid, and the extract stream comprising the diacid and components less polar than the diacid; (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 diacid, thereby separating a C6- to C18-carbon diacid from the at least one impurity in the solution.
