| 摘 要： | 进行减压蒸馏实验，采用直立式“Ｕ”形压力计替代真空表，用壁厚３ｍｍ的下嘴瓶代替干燥塔，并自制部分联接件，由实验给出的数据表明，这样做是可行的。文章还从操作、气压计校正、理论计算等方面讨论了减压蒸馏中出现的ｂ．ｐ（沸点温度）随系统压力增大出现偏差的现象，证明这种改进后的实验能在普通高校开设。

| Abstract: | The experiment data indicates that vacuum distillation experiment can be made by using vertical U - shape mamometer instead of vacuum meter, 3mm sub - mouth bottle instead of desiccator and self - made some con necting parts. The paper also discusses the declination phenomenon appearing the b. p in vacuum distillation the pressure becomes higher through operation, adjustment of barometer, theoretical calculation, and finally it proves that the experiment improved mentioned above can be run in the higher colleges and universities. |
