为了分离乙醇-异丙醇混合物,研究了共沸精馏在乙醇-异丙醇物系中的应用。根据共沸剂的选取原则选定出1-己烯作为共沸精馏分离乙醇-异丙醇混合物的共沸剂,使用ASPEN模拟软件模拟连续和间歇共沸精馏分离乙醇-异丙醇工艺流程,并通过间歇共沸精馏实验考察了所选共沸剂的分离效果。结果表明：使用1-己烯作为共沸剂能成功的分离乙醇-异丙醇混合物;采用有30块理论板的填料塔,回流比为25,共沸剂1-己烯与乙醇的质量比为4∶1,塔釜异丙醇的质量分数达到99.77%。

Azeotropic distillaition was used to separate ethanol-isopropanol mixture.According to principles of the selection of entrainer,1-hexene was selected for the separation.Aspen plus software was used to simulate continuous and batch azeotropic distillation flow process.In addition,the effectiveness of the selected entrainer was investigated by the batch azeotropic distillation experiment.The results showed that 1-hexene can be a successful entrainer to separate the ethanol-isopropanol mixture.The separation experiment of ethanol-isopropanol mixture by batch azeotropic distillation was carried out in a packed column with 30 theoretical plates.The reflux ratio was 25,and the 1-hexene and ethanol mass ratio was 4∶1.The product mass fraction of isopropanol reached 99.77%.
