The reduced pressure distillation experiment on the liquid paraffin was done and the Engler distillationcurve was obtained.
进行了石蜡油的减压蒸馏实验，得到了恩氏蒸馏曲线。

So then, in a practical way, it's possible to walk quite far along the distillation, the coexistence curve, and distill to really a high degree of purification.
如此反复，实际过程中，可以沿着，共存曲线蒸馏很久，然后提纯到一个很高的纯度。

This model austerely simulating dynamic action of vacuum distillation unit, and the dynamic curve of vacuum's sidetrack from feed-in to static state.
