微负压精馏法回收丙酮溶媒

Acetone Solvent Recovery by Minute Vacuum Distillation

利用压力对丙酮-水体系气液相组成的影响,采用微负压精馏的方法,制备含水率低于0.5%的高纯度丙酮,可以达到比常规方法节能49%以上的效果。

Using the effect of pressure on the vapour and liquid phase equilibrium composition of acetone-water system,prepare the high purity acetone with the moisture content less than 0.5% by using the minute vacuum distillation.Compared with the conventional method,it would produce a good result to save the energy more than 49%.
