Results from 141 data points show that Margules equation is much better than both van Laar and Wilson equations. 141个数据点的计算结果表明,Margules方程显著优于vanLaar方程和Wilson方程。
In the present paper, we have calculated the liquid-liquid equilibrium data with quite satisfactory results, for six binary systems of organic aqueous solution by using van der Waals equation, modified by the theory of molecular aggregation and van Laar mixing rule. 本文应用由分子聚集理论改进的vanderwaals方程和vanLaar混合规则对六个有机物水溶液体系的液液平衡进行了计算,取得了满意的结果。
The van Laar equation was expended, introduced the temperature effect in it. The liquid-liquid equilibrium data were correlated by corrected van Laar equation, NRTL and van laar equation. 对vanLaar方程作了修正,用来关联上述体系的液&液平衡数据,并与NRTL和vanLaar原方程关联结果进行了比较。
Based on the Van Laar equation the activity coefficients are calculated of propylene carbonate and water in the binary solution of propylene carbonate water, and then by means of the Raoult Law for non ideal solutions the vapor partial pressures of propylene carbonate and water are calculated. 从vanLaar方程出发,推算碳酸丙烯酯-水二元系溶液中碳酸丙烯酯和水的活度系数,然后再利用非理想溶液的Raoult定律,分别算出碳酸丙烯酯和水的蒸汽分压。
The phases equilibrium constants of the five key components in the synthesis ammonia system at different temperature and pressure are predicted by the modified R-K EOS combined with Van Laar's activity coefficient equation and CCOR EOS respectively. 本文应用改进R-K状态方程和vanLaar型活度系数方程预测不同温度和压力下合成氨体系五个关键组分的相平衡常数;
The systems were correlated by the Wilson equation and Van Laar equation, and the correlated results were in fairly good agreement with the measured data. 用Wilson方程及vanLaar方程关联无盐及溶盐体系,结果表明,两种方程的计算值与试验值吻合良好。
