Abstract

Complex ferric salts of (1,2-ethanol diimino) bis (5-carboxy 2-hydroxy phenol acetic acid, of formula (I) (where M is K, Na or NH4) are made by reacting the acid with a ferric salt e.g. FeCl3 and an alkaline hydroxide, e.g. KOH, NaOH or NHaOH, in aq. medium so that the final pH is 6-8, at 0-50 deg. C.
