| 摘 要： | 利用二元理想液态混合物性质及安托因方程推导了稀溶液泡点随挥发性溶质浓度变化的关系,并借助苯-甲苯、正己烷-环己烷体系相图数据计算溶质的饱和蒸气压,与安托因方法得到的结果符合良好;将此关系推至真实溶液中,可以计算亨利常数与无限稀释的活度系数.本文对多个溶液体系进行了计算,计算结果与文献数据较为符合.

| Abstract: | The relationship between bubble point for dilute solution and the content of volatile solute was derived from the properties of binary ideal fluid mixtures.The solute vapor pressure calculated from this relation,by benzene-toluene,hexane-cyclohexane phase diagram data,fitted well the results from Antoine-methods.The henry's constant and the infinite diluted activity coefficient can also be calculated from the equation derived for non-ideal liquid mixtures.The results were also correspondence with those lite... |
