摘要
本文研究了题述三元体系在３０℃的相平衡，测定了饱和溶液的溶解度及其折光指数，绘制了相应的溶度图和折光指数一组成关系图．Ｚｎ（ＮＯ_３）_２体系溶度曲线及折光指数曲线由两支组成，分别与Ｚｎ（ＮＯ_３）_２·６Ｈ_２Ｏ和ＣＨ_３ＣＯＮＨＣＯＮＨ_２相对应，该体系为简单共饱型，共饱点的组成含Ｚｎ（ＮＯ_３）_２ ５０．８６％和ＣＨ_３ＣＯＮＨＣＯＮＨ_２ １１．７０％．相平衡的数据可以用来指导合成缓释肥料。
The solubility and refractive indices of saturated solution of the ternary system at 30℃ have been studied and the corresponding equilibrium diagrams are constuct- ed. The system of Zn(NO3)2 is a simple one. The eutectic compositions are Zn(NO3)2 50. 86% and CH3CONHCONH2 11.70%.The phase equilibrium data can be used in formulat- ing controlled release fertilizers.
