| titleOfInvention |
Preparation of α-alaninediacetic acid or its alkali metal or ammonium salts |
| abstract |
The invention relates to a process for preparing β-alaninediacetic acid (Ia) or its alkali metal or ammonium salts (Ib) which comprises reacting iminodiacetic acid with acrylonitrile or C 1 -C 4 -alkyl acrylates in weakly acid to weakly basic aqueous medium and subsequently hydrolyzing the nitrile or ester moiety to the acid or a salt. n The products prepared according to the invention can be used, in particular, to form complexes. |
