Abstract

Abstract : For the first time, a carbon molecular sieve was obtained via carbonization of a metal–organic framework, exhibiting excellent performance in paraffin/iso-paraffin separation. Abstract : We unveil a unique kinetic driven separation material for selectively removing linear paraffins from iso-paraffins via a molecular sieving mechanism. Subsequent carbonization and thermal treatment of CD-MOF-2, the cyclodextrin metal–organic framework, afforded a carbon molecular sieve with a uniform and reduced pore size of ca. 5.0 Å, and it exhibited highly selective kinetic separation of n -butane and n -pentane from iso-butane and iso-pentane, respectively.
