摘要
由于二甲苯异构体的沸点相差很小,用普通精馏方法分离二甲苯异构体比较困难,从增大二甲苯异构体之间的相对挥发度入手,能够使它们部分分离。总结了国内外利用特殊精馏法分离二甲苯异构体的研究进展,并对其进行了展望。
It is difficult to separate xylene isomers by conventional disillation method for the boiling point range of xylene isomers is small. Xylene isomers can be partially saparated by increasing the relative volatility of them.Advances in separation of xylene isomers by special distillation method are summarized. The development trends intbe future are prospected as well.
