    Abstract: Aminomethylene phosphinic acid derivs. contg. units of formula (I), soluble in hydrocarbons, or aminomethylene phosphonic acid derivs. contg. units of formula (Ia), or aminomethylene phosphonic acid derivs. of formula R R N-(A-N(R ))pR (II), are used in the extn. of Fe ions from aq. solns. In the formulae: R and R = H, 1-30 C alkyl (opt. carrying up to 15 OH gps. and/or broken by up to 14 non-adjacent O atoms), or 2-30 C alkenyl, 7-18C aralkyl, or 6-14C aryl (opt. substd. with up to 3 1-12C alkyl or alkoxy, halogen, CN, OH or 1-4C alkoxycarbonyl; R -R = H, 1-30 C alkyl (opt. carrying up to 15 OH gps. and/or broken by up to 14 non-adjacent O atoms), 2-30 C alkenyl, 7-18C aralkyl, 6-14C aryl (opt. substd. with up to 3 1-12C alkyl or alkoxy, halogen, CN, OH or 1-4C alkoxycarbonyl), or are gps. of formulae -CR R -PO3H2, -CH2-COOH or -CH2-CH(OH)-R ; at least one of the gps. R -R = -CR R -PO3H2, and at least one other is 6-30C alk(en)yl, 7-18C aralkyl, (substd.) 6-14C aryl or -CH2-CH(OH)-R ; R = 6-30 C alk(en)yl, 7-18C aralkyl or (substd.) 6-14 C aryl; A = 1-12C alkylene (opt. substd. with up to 3 1-30 C alkyl, 2-30C alkenyl, 7-18C aralkyl, or 6-14C aryl, which in their turn may be substd. by up to 3 1-12C alkyl or alkoxy, halogen, CN, OH, or 1-4C alkoxycarbonyl); and p = 0-30,000. Also claimed is a modifier for use in the sepn. of metal ions from aq. solns. by solvent extn..
