A process for purifying a filtered fermentation broth of succinic acid is described. The process involves separating succinic acid from the other organic acids and salts in. a raw filtered broth using a non- functionalized chromatographic resin. The operation can be run either as an isocratic elution to yield free succinic acid(cas:110-15-6), or as a gradient or binary elution to produce succinate salt.
BENEFIT OF PRIORITY
The present application claims benefit of priority of provisional application Ser. No.

FIELD OF THE INVENTION
The present invention relates to a process lor the separation of succinic acid(cas:110-15-6) and/or dibasic succinate trorn a fermentation broth. In particular, the invention pertains to a method of purifying succinic acid(cas:110-15-6) and/or its sah that involves using chromatography on non- uusctionahzed resins.
The present invention has been described in general and in detail by way of examples.
Persons of skill in the art understand that the invention is not limited necessarily to the embodiments specifically disclosed, but that, modifications and variations may be made without departing from the scope of the invention as defined by the following claims or their equivalents, including other equivalent components presently known, or to be developed, which may be used within the scope of the present Invention. Therefore, unless changes otherwise depart from the scope of the invention, the changes should be construed as being included herei .
