A CHARGE-ASSISTED HYDROGEN-BONDED ORGANIC FRAMEWORK FOR SELECTIVE SEPARATION OF P-XYLENE

Authorship SCIMAGO INSTITUTIONS RANKINGS

A charge-assisted hydrogen-bonded organic framework (HOF) FJU-201 is constructed by N,N’-bis(5-isophthalic acid)naphthalimide divalent anion (H2L2-), p-xylene and dimethylammonium. FJU-201 can only crystallize in solutions containing p-xylene, and cannot crystallize in both o-xylene and m-xylene. FJU-201 can also crystallize in xylene mixtures with the content of p-xylene is not less than 50%, which can be used for separating and purifying p-xylene, and it has good recyclability.

Keywords:
hydrogen-bonded organic framework; p-xylene separation; selectivity
