Abstract For this article, we investigated the phase behavior and physicochemical properties of the ternary systems MCl (M = Na, K, Rb, Cs) + tetramethylurea (TMU) + H2O at temperatures of 288.2, 298.2 and 308.2 K. For (solid–liquid) equilibrium (SLE) systems (NaCl/KCl/RbCl + TMU + H2O at three temperatures and CsCl + TMU + H2O at 288.2 K), the density, solubility and refractive index about the saturated solutions was obtained. About (liquid–liquid) equilibrium (LLE) systems (CsCl + TMU + H2O at 298.2 and 308.2 K), the binodal curves and tie lines were obtained. The three parameter equation, Othmer-Tobias and Bancroft equations were used to correlate the SLE and LLE data.

四甲基脲 + MCl(M = Na、K、Rb、Cs)+ H2O 系统在 288.2、298.2 和 308.2 K 下的相行为

摘要 在本文中,我们研究了三元体系 MCl(M = Na、K、Rb、Cs)+ 四甲基脲 (TMU) + H2O 在 288.2、298.2 和 308.2 K 的温度下的相行为和物理化学性质。对于(固体-液体)平衡(SLE)系统(NaCl/KCl/RbCl + TMU + H2O 在三个温度下和 CsCl + TMU + H2O 在 288.2 K),获得了饱和溶液的密度、溶解度和折射率。关于(液-液)平衡(LLE)系统(CsCl + TMU + H2O 在 298.2 和 308.2 K),获得了双节点曲线和连接线。三参数方程、Othmer-Tobias 和 Bancroft 方程用于关联 SLE 和 LLE 数据。
