摘要
本研究采用精密泡罩塔、全回流工艺，考察了ＣａＣｌ＿２、ＫＡｃ两种盐对乙醇──水体系分离效率的影响，并进行了热力学推算。从小型工艺试验结果看，溶盐精馏过程能得到高浓度的乙醇。
In the paper,it is studied that CaCl_2 and KAc have an effect on C_2H_5OH-H_2O containing salt systems which separated by means of accurate tower and return process,and thermo dynamical calculation is carried.with the results of distillation of containing salt,the high concentration alcohol were obtained at the top of tower.
