Abstract:
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, or as a gradient or binary elution to produce succinate salt.
