摘要
本实验采用平衡法测定了在283．15～313．15K范围内，乙基麦芽酚在纯水及正丙醇-水不同比例混合溶剂中的溶解度；实验数据分别用多项式模型和半经验活度模型进行了模拟。模拟结果表明，在实验条件范围内，半经验活度方程模拟结果优于具有相同参数的多项式方程，其相关系数R^2均大于0.981，且精度满足工程预测要求。
Abstract.The solubility of ethyl maltol in water and mixed solvent of different ratio of 1-propyl alcohol-water was measured in the temperature ranging from 283.15K to 313.15K by the equilibrium method.Experimental datas were respectively simulated by the polynomial and semi-empirical activity equation.And the results showed that the semi-empirical equation was better than with polynomial equation in the range of experimental conditions.
