我们曾进行金属盐-冠醚-溶剂三元体系溶解度的研究。本文主要报导Pr(NO_3)·4H_2O-B15C5-CH_3CN(或C_2H_5OH)在18℃(或25℃)时溶解度的研究结果。关于水合硝酸镨与冠醚B15C5的络合物曾为A·Cassol等和R.B.King等分别在乙腈和丙酮中研究过。本文将对这些结果进行讨论。
We conducted a study of the solubility of metal salt-crown ether-solvent ternary systems. This article reports the results of a study of the solubility of Pr (NO_3) · 4H_2O-B15C5-CH_3CN (or C_2H_5OH) at 18 ° C (or 25 ° C). Complexes of hydrated praseodymium nitrate with crown ether B15C5 have been studied by A. Cassol et al. And R.B. King et al. Respectively in acetonitrile and acetone. This article will discuss these results.
