ABSTRACT:
A novel separation process of an iminodiacetic acid component from an aqueous glycine solution including the same is provided. In this process, sulfuric acid is added, in the presence of sodium salt, to the aqueous glycine solution in such an amount that the pH of the aqueous glycine solution becomes 1.5 or less, whereby the iminodiacetic acid is crystallized from the solution and, then, the crystallized iminodiacetic acid component is separated from the mother liquor. Thus, glycine can be efficiently recovered without causing undesirable accumulation of the iminodiacetic acid component in the mother liquor.
