摘要
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。
The isothermal solubilities of MgSO_4-C_2H_5OH-H_2O ternary system at-5, 0,25,30.35 and 50℃have been determined, the liquid-solid phase diagram has been drawn out andthe equilibrium vapor pressures have been determined by static pressure method at 25℃ and30℃ respectively. According to Jaque′s pseudobinary model,the Wilson equation and NRTLequation have been tested to calculate the vapor-Jiquid equilibrium data of the system. Itis shown that NRTL equilibrium equation is more agreeable with the experimental values.
