摘要

The hydrolysis and ammonolysis of EDTA were studied in aqueous solution over a range of temperatures and at various pH values with the aid of nmr, gc, and gc-mass spectroscopic techniques. At high pH in the presence of ammonia, both ammonolysis and hydrolysis occur with the production of N-(2-aminoethyl) iminodiacetic acid (UEDDA), N-(2-hydroxyethyl)- iminodiacetic acid (HEIDA), and iminodiacetic acid (IDA) in molar ratios such that [IDA]=[ ...
