| 摘 要： | 用动态法分别测定了283.15~333.15 K温度范围内季戊四醇在不同比例乙醇—水混合体系中的溶解度,由实验数据可以看出季戊四醇在不同比例乙醇—水体系中的溶解度均随温度的增加而增大。同时采用λh方程、Apelblat方程对实验数据进行了关联,结果表明这两种方程均能较好的关联季戊四醇在乙醇—水体系中的溶解度数据。

| Abstract: | The solubility of pentaerythritol in different proportion ethanol water mixed system at 283.15 -333.15 K are determined by dynamic method ,the experiment data shows the solubility of pen- taerythriton increase with temperature increasing. At the same time, the experiment data are related by e- quation and apelblat equation, the result shows the two equation both can better related the solability data of pentaerythritol in ethanol - water system. |
