Abstract
(EN)
Provided are a use of the phosphoryl carboxylic acid represented by general formula I below or a salt thereof in separating yttrium and a method. R1 is substituted or unsubstituted C1-4 linear alkylene, and the substituted substituent is selected from among C1-3 alkyl or phenyl; R2 and R3 are each independently selected from among C1-12 alkyl, C1-12 alkoxy, C1-12 alkoxy substituted C1-6 alkyl, and C1-12 alkoxy substituted C1-6 alkoxy; and the total number of carbon atoms of R1, R2 and R3 is greater than 10. The used phosphoryl carboxylic acid extractant is easy to synthesize, and the chemical raw materials used for synthesis are simple and easy to obtain and are low-cost, which may effectively reduce the costs of separating yttrium from other rare earth elements, and which has high industrial application value.

L'invention concerne une utilisation de l'acide phosphoryl carboxylique représenté par la formule générale I ci-dessous ou d'un sel de celui-ci en séparation d'yttrium et un procédé correspondant. Dans la formule, R1 représente un groupe alkylène en C1-4 linéaire substitué ou non substitué et le substituant est choisi parmi les substituants alkyle en C1-3 ou phényle ; R2 et R3 sont chacun indépendamment choisis parmi les groupes alkyle en C1-12, alcoxy en C1-12, alkyle en C1-6 substitué par alcoxy en C1-12 et alcoxy en C1-6 substitué par alcoxy en C1-12 ; et le nombre total d'atomes de carbone de R1, R2 et R3 est supérieur à 10. L'agent d'extraction acide phosphoryl carboxylique utilisé est facile à synthétiser et les matières premières chimiques utilisées pour la synthèse sont simples et faciles à obtenir et sont peu coûteuses, ce qui permet de réduire efficacement les coûts de séparation d'yttrium à partir des autres éléments des terres rares et ce qui présente une haute valeur d'application industrielle.
