    Abstract: Process for preparation of a mixture of methyl glycine diacetic acid (MGDA) or its respective mono-, di-, trialkali metal salt or its respective mono-, di- or tri-ammonium salt or mixtures thereof, and glutamic acid diacetic acid (GLDA) or its respective mono-, di-, tri-, or tetra-alkali metal or mono-, di-, tri- or tetra-ammonium salt or mixtures thereof, wherein said process com-prises the steps of: (a) dissolution in water of (a1) alanine in its L- or D-enantiomeric form or its respective monoalkali metal salt or mixtures thereof, and (a2) glutamic acid as L- or D-enantiomer or its respective mono-, or dialkali metal or mixtures thereof, wherein the molar ratio of alanine to glutamic acid is in the range of from 1:9 to 9:1, (b) converting the mixture obtained in step (a) with formaldehyde and hydrocyanic acid or alkali metal cyanide to the corresponding dinitriles, (c) saponification of the dinitriles resulting from step (b).
