| 摘 要： | 利用静态法测定了不同温度下Ｃ４烃在ＤＭＦ中的蒸气压与组成的关系曲线，与纯Ｃ４的蒸气压曲线比较，可以看出，ＤＭＦ改变了正丁烷与其它Ｃ４烃之间的相对挥发性关系，这为萃取精馏法分离烷烃和烯烃提供了依据。为了验证，还测定了正丁烷和１－丁烯在ＤＭＦ中的相对挥发度。

| Abstract: | The P x curves of C 4 hydrocarbons dissolved in DMF was determined with a static method When the experimental data are compared with the saturated vapor curves of pure C 4 hydrocarbons,it can be shown that DMF increases the relative volatility of n butane to other C 4 hydrocarbons Therefore,it is possible that butanes and butenes can be separated by extractive distillation using DMF as extractive solvent In addition,vapor liquid equilibrium constants of n butane 1 butene DMF system were determined,and a mathematical model was established to verify the experimental data |
