摘要
本文采用加盐萃取精馏方法制备无水乙醇.在设计的精馏装置中和按选定的工艺条件进行试验,可使所制备的无水乙醇纯度达到99.8%。另外,还对所述精馏装置提出了一种简便的近似设计方法。
Anhydrous alcohol is prepared by salt-adding extractive distillation. Experiments have been carried out under selected conditions with the distillation device designed by the author. The purity of the obtained anhydrous alcohol can reach to 99.8%. Moreover, a simple approximate method for designing the mentioned distillation device is proposed.
