Trisodium Dicarboxymethyl Alaninate
Trisodium ''N''-(1-carboxylatoethyl)iminodiacetate, methylglycinediacetic acid trisodium salt (MGDA-Na3) or trisodium α-DL-alanine diacetate (N-(2-Carboxyethyl)iminodiacetic acid, α-ADA), is the trisodium anion of ''N''-(1-carboxyethyl)iminodiacetic acid and a tetradentate complexing agent. It forms stable 1:1 chelate complexes with cations having a charge number of at least +2, e.g. the "Hard water, hard water forming" cations Calcium, Ca2+ or Mg²⁺, Mg2+. α-ADA is distinguished from the isomeric β-alaninediacetic acid by better biodegradability and therefore improved environmental compatibility. Production The patent literature on the industrial synthesis of trisodium ''N''-(1-carboxylatoethyl)iminodiacetate describes the approaches for solving the key requirements of a manufacturing process that can be implemented on an industrial scale, characterized by * Achieving the highest possible space-time yields * Simple reaction control at relatively low pressures and temperat ...

N-(2-Carboxyethyl)iminodiacetic Acid
''N''-(2-Carboxyethyl)iminodiacetic acid or β-ADA (β-alanine diacetate) is an organic compound with the formula . It is a white solid. The compound is classified as an aminocarboxylic acid, formally a derivative of glycine. Ligand properties The conjugate base is tetradentate complexing agent that forms 1:1 complexes with cations having a charge number of at least +2, e.g. the "Hard water, hard water forming" cations Calcium, Ca2+ or Magnesium, Mg2+. ''N''-(2-Carboxyethyl)iminodiacetic acid should not be confused with α-alaninediacetic acid, also known as methylglycinediacetic acid (MGDA) or α-ADA. Alkaline earth and heavy metal complexes of both, α-ADA and β-ADA are biodegradable (in contrast to chelate complexes with conventional complexing agents such as Ethylenediaminetetraacetic acid, EDTA). Production ''N''-(2-carboxyethyl)iminodiacetic acid was first prepared from Β-Alanine, β-alanine and Monochloroacetic Acid, monochloroacetic acid as reported by Gerold Schwa ...
