近年来,虽然对冠醚12-冠-4与稀土硝酸盐配合物的研究已有一些工作,但对单环1,2-环已基-12-冠-4与稀土硝酸盐的配合物的研究,仍未见报道。本文报道稀土硝酸盐与单环己基-12-冠-4配合物的合成和性质研究。 1 实验部分 1.1 试剂与仪器 RE(NO_3)_3-xH_2O(x=3～5)的制备是将纯度99.9％的RE_2O_3溶于浓硝酸(A.R.)中,微热浓缩成糊状,冷至室温。置于盛有P_2O_5的保干器中备用。单环1,2-环已基-12-冠-4系上海试剂一厂产品。其余试剂均为分析纯,并在使用前经过进一步纯化及干燥处理。所
In recent years, although some work has been done on the study of crown ether 12-crown-4 and rare earth nitrate complexes, the complex of the monocyclic 1,2-cyclohexyl-12-crown-4 with the rare earth nitrate Research, has not been reported. This paper reports the synthesis and properties of rare earth nitrate complexes with monocyclohexyl-12-crown-4. 1 Experimental 1.1 Reagents and equipment RE (NO_3) _3-xH_2O (x = 3 ~ 5) was prepared by dissolving 99.9% pure RE_2O_3 in concentrated nitric acid (A.R.), slightly concentrated to a paste and cooled to room temperature. Placed in P_2O_5 drying dryer spare. Monocyclic 1,2-cyclohexyl-12-Crown-4 Department of Shanghai Reagent Products. The remaining reagents are of analytical grade and are further purified and dried before use. The
