Abstract

This work presents the results of studies of extraction properties in relation to the uranium of bis(2,2,2- trifluoroethyl)diallylamido phosphite, bis(2,2,2-trifluoroethyl)dimethylamido phosphite, and bis(N,Ndialamido)isopropyl phosphite synthesized by us earlier. Tests were carried out in a factory laboratory, as the initial solutions used nitrate solution prepared from uranium oxide (CU = 10.30 g/dm3 , CHNO3 = 56.40 g/dm3 ) and uranium sulfate solution prepared from the chemical concentrate of natural uranium and deoxidized with sulfuric acid (CU = 10.60 g/dm3 , CH2SO4 = 25.10 g/dm3 ). It was proved that the synthesized acyclic amido phosphites can effectively extract uranium from these technological solutions with a proper selection of technological parameters, and the degree of uranium extraction may vary from 34.43 to 95.94%.

合成氟化有机磷化合物的萃取性能

本文介绍了我们先前合成的二(2,2,2-三氟乙基)二烯丙基亚磷酸酯、二(2,2,2-三氟乙基)二甲基亚磷酸酯和二(N,Ndialamido)异丙基亚磷酸酯对铀的萃取性能的研究结果。试验在工厂实验室进行，初始溶液使用由氧化铀(CU = 10.30 g/dm3, CHNO3 = 56.40 g/dm3)制备的硝酸盐溶液和由天然铀的化学浓缩物制备的硫酸铀溶液(CU = 10.60 g/dm3, CH2SO4 = 25.10 g/dm3)。结果表明，只要选择适当的工艺参数，合成的无环氨基亚磷酸酯能有效地从这些工艺溶液中提取铀，铀的提取率在34.43% ~ 95.94%之间。

期刊介绍： RASĀYAN Journal of Chemistry [RJC] signifies a confluence of diverse streams of chemistry to stir up the cerebral powers of its contributors and readers. By introducing the journal by this name, we humbly intent to provide an open platform to all researchers, academicians and readers to showcase their ideas and research findings among the people of their own fraternity and to share their vast repository of knowledge and information. The journal seeks to embody the spirit of enquiry and innovation to augment the richness of existing chemistry literature and theories. We also aim towards making this journal an unparalleled reservoir of information and in process aspire to inculcate and expand the research aptitude.
