Reaktionsschritte

A sample of 50 grams of L-aspartic acid was placed in a 1-liter beaker. To this, 50 ml of distilled water were added and magnetically stirred to form a slurry that contained 0.3755 moles of aspartic acid. Next, 75.1 ml of 10 N NaOH (Fisher Scientific) were slowly pipetted into the solution, thereby adding 0.751 moles of sodium (30.04 grams as NaOH). This solution was not lyophilizible, but was dried first at 120° C. for four hours to form a viscous liquid, then at 150° C. for four more hours which on cooling yielded a white, crystalline mass of disodium aspartate.
