Abstract
Process for the preparation of ferriquelates from hydrolysis products of ethylene-bis- (alpha-imino-orthohydroxyphenylacetonitrile), characterized in that iron salts are reacted in the presence of alkaline reagents with dihydrochlorides of hydrolysis products such that their content in nitrogen is between 6.9 and 9.9% and whose potentiometric titration in aqueous medium by means of sodium hydroxide solution in the presence of stoichiometric quantities of a ferric salt indicates at ph between 7.5 and 9.5 the formation of a hydroxoquelate in an amount of at least 10%.
