H测定过MgSO_4-C_2H_5OH-H_2三元系在25℃、50℃、75℃的液固平衡和部分不饱和溶液汽液平衡的总压和分压。本文补充了30℃、0℃和-5℃时的溶解度数据,得到分层温度和浓度范围,绘出了溶解度图。测定了25℃和30℃饱和溶液的密度,粘度和平衡总压力。根据Jaques“假二元系”理论用Wilson、Uniquac和NRTL活度方程计算了溶
H The total pressure and partial pressure of the liquid-solid equilibrium of MgSO_4-C_2H_5OH-H_2 ternary system at 25 ℃, 50 ℃ and 75 ℃ and the vapor-liquid equilibrium of partially unsaturated solution were measured. This article supplements the solubility data at 30 ° C, 0 ° C and -5 ° C to obtain the stratification temperature and concentration range and plot the solubility. The density, viscosity and equilibrium total pressure of the saturated solution at 25 ° C and 30 ° C were measured. According to Jaques “pseudo-binary system” theory Wilson, Uniquac and NRTL activity equation was calculated
