The invention provides a process for the production of aspartic acid poly-condensate from a carbohydrate comprising the steps of: fermenting a carbohydrate-containing medium by means of a fumaric acid-producing microorganism, whereby a fumarate-containing fermentation liquor is formed; forming a purified ammonium fumarate solution from the fumarate-containing fermentation liquor; enzymatically converting the purified ammonium fumarate into purified ammonium aspartate; heating an aqueous solution of an aspartate salt derived from the purified ammonium aspartate whereby water is removed, an aspartic acid condensate is formed and a second product is formed, which second product is basic and contains the cation of the aspartate salt; and removing and using the basic second product as a reagent in another step of the process.

Process for the production of aspartic acid condensate

The invention relates to a process for the preparation of aspartic: acid by decomposition of ammonium aspartate wherein a concentrated aqueous solution of ammonium aspartate is continuously introduced into a diluent in which water has a low solubility, which diluent is maintained at a temperature at which ammonium aspartate decomposes into aspartic acid and ammonia, and wherein the water and the formed ammonia are continuously removed. The invention also relates to a process for preparing polysuccinimide starting from fumaric acid or maleic acid and ammonia involving said process for preparing aspartic acid from ammonium aspartate.
