PURIFICATION OF SUCCINIC ACID

摘要

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.
