Description

Extraction of acid and interphase distribution of 1-alkyl-3-methyl-2-pyrazoline-5-ones in the system water-chloroform-perchloric acid are studied. Reagents capable to extract scandium cations from subacid solutions in the presence of perchlorate ions. 1-Alkyl-3-methyl-2-pyrazoline-5-ones stratifies aqueous solutions of perchloric acid into two liquid phase. Scandium ions are concentrated in the lower phase having small volume

Abstract (Russian)

Изучены экстракция кислоты и межфазное распределение 1-алкил-3-метил-2-пиразолин-5-онов в системе вода-хлороформ-хлорная кислота. Реагенты способны экстрагировать катионы скандия из слабокислых растворов в присутствии перхлорат-ионов. 1-Алкил-3-метил-2-пиразолин-5-оны расслаивают водные растворы хлорной кислоты на две жидкие фазы. Ионы скандия концентрируются в нижней фазе, имеющей малый объем
