Abstract
Ethyleneglycol - bis - (b - aminoethylether)-N,N1 -tetraacetic acid is prepared by reacting 1 mol. of triethylene glycol dichloride with at least 2.2 mols. of disodium iminodiacetate and acidifying the resultant tetrasodium salt. The reaction is preferably effected in glycerol solution or in an aqueous dispersion wherein an emulsifier, e.g. oleic acid, is used, and in the presence of an alkaline material, e.g. sodium carbonate or hydroxide, at about 50 DEG C. to 200 DEG C. The free acid may be obtained by acidifying the tetrasodium salt so obtained with an inorganic acid and may be purified by refluxing with formic acid. Specification 695,346 is referred to.
