Description

Adducts soluble in polar organic solvents and insoluble in water are synthesized by interaction of complex inorganic acid (CIA) with substituted polyethylene glycols in acid medium. Adducts compositions depend on medium acidity during synthesis and properties are determined by polyethylene glycols structure and CIA type. With increase of polyethylene glycols content extraction ability of adducts decreases, solubility in polar organic solvents increases, and passes through minimum in water. Extraction of Cs, Sr, Ba, Eu, and Am from HNO3 is studied

Abstract (Russian)

Взаимодействием комплексных неорганических кислот (КНК) с замещенными полиэтиленгликолями в кислой среде синтезированы аддукты, нерастворимые в воде и растворимые в полярных органических растворителях. Состав аддуктов зависит от кислотности среды при синтезе, а свойства определяются структурой полиэтиленгликолей и видом КНК. С увеличением содержания полиэтиленгликоля экстракционная способность аддуктов падает, растворимость в полярных органических растворителях растет, а в воде - проходит через минимум. Изучена экстракция Cs, Sr, Ba, Eu и Am из HNO3
