Selective Adsorption and Separation of Xylene Isomers and Ethylbenzene with the Microporous Vanadium(IV) Terephthalate MIL-47

摘要

The separation of mixed C8 alkylaromatic compounds is one of the most challenging issues in the chemical industry because of its direct link with PET manufacture,for example.Distillation is only feasible for the removal of o-xylene;it fails for the other C8 alkylaromatic compounds because of the similarity of their boiling points (p-xylene: 138°C,m-xylene: 138-139°C,and ethylbenzene: 136°C).
