Date Nov. 25, 1993.The invention relates to a process for preparing beta -alaninediacetic acid (Ia) or its alkali metal or ammonium salts (Ib) which comprises reacting iminodiacetic acid with acrylonitrile or C1-C4-alkyl acrylates in weakly acid to weakly basic aqueous medium and subsequently hydrolyzing the nitrile or ester moiety to the acid or a salt. The products prepared according to the invention can be used, in particular, to form complexes.
