Pervaporation, as one of high efficient and economic membrane separation methods, is capable of separating azeotropic and near-boiling point mixtures. 渗透汽化分离是一种高效、节能的分离技术,特别适用于近沸及恒沸混合物的分离。
The experiments proved that [ EMIM]+ [ BF4]-could withdraw the azeotropic point of ethanol-water system and could be used as the extractive distillation solvent for the separation of ethanol and water. 实验表明:[EMIM]+[BF4]-可以消除乙醇-水体系的共沸点,可以作为萃取精馏分离乙醇-水体系的溶剂。
Measurement and Prediction of Ternary Azeotropic Point 三元系共沸点的测定及预测
Owning to the predominant advantages in separating azeotropic and close-boiling point mixtures, batch azeotropic distillation is being paid more and more attention. 由于在分离共沸物或相近沸点混合物方面优点突出,间歇共沸精馏正受到日益广泛的重视。
