The possibility of unique azeotropy or polyazeotropy in a liquid mixture can be predicted using activity coefficient models in terms of boiling point calculation.
在存在共沸点的条件下， 利用活度系数关联式， 通过泡点计算求出共沸条件。

As the one of the preferred embodiment, the method USES hog still to remove water and aromatic hydrocarbon organic solvent azeotropy generated in the dehydration reaction.
作为优选的实施方式之一，使用蒸馏塔将在上述脱水反应中生成的水与芳香烃类有机溶剂共沸除去。
