摘要
报道了CuSO4(ZnSO4)-CO(NH2)2-H2O 两个三元体系在30 ℃时的等温溶度及饱和溶液的折光率, 绘制了相应的溶度图和折光率-组成图. 两个三元体系中分别形成了组成为CuSO4·3CO(NH2)2·H2O(异成分溶解)和ZnSO4·CO(NH2)·2H2O(同成分溶解)的化合物, 并通过元素分析、红外光谱。
CuSO 4 CO(NH 2) 2 H 2O and ZnSO 4 CO(NH 2) 2 H 2O ternary systems have been investigated by isothermal method at 30 ℃. Their solubility diagrams and refractive index composition diagrams have been constructed. New ternary compounds formed in each system respectively, CuSO 4·3CO(NH 2) 2·H 2O incongruently dissolved in the former system and ZnSO 4·CO(NH 2) 2·2H 2O congruently dissolved in the latter and new compounds were confirmed by IR, TG and X ray diffraction methods.
