摘要
本文研究了1,10-双(1-苯基-3’-甲基-5’-氧代吡唑-4’-基)癸二酮-〔1,10〕从硝酸溶液中对Sc、Y、La的萃取分离。测定了固态萃合物的溶解性、摩尔电导、热稳定性及UV、IR、~1H NMR谱,讨论了萃合物的可能结构。
Scandium, yttrium and lanthanum have been extracted and separated by 1, 10-bis (1' -phenyl-3' -methyl-5' -oxopyrazol-4' -yl) -1, 10-decanedione in nitric acid. The extracted com-plexes were isolated and examined by elemental analysis, thermal analysis, UV, IR, ~1HNMR,molar conductances and the solubility determinations.
