A Complete Separation of Hexane Isomers by a Functionalized Flexible Metal Organic Framework

Abstract: wileyonlinelibrary.comsuch as the mono-branched hexane isomer 3MP are usually still present and contribute to decrease the performance of the process. To overcome this drawback, there is a crucial need to search for alternative porous solids able to more selectively adsorb di-branched compounds such as the 22DMB from the mono-branched 3MP and linear nHEX.As a typical example, it was demonstrated that zeolite BETA could be used to upgrade the actual TIP processes by partially separating mono from di-branched he… Show more

“…Many important separation processes in petrochemical industry are gas or vapor phase separation, such as removing acetylene from ethylene, paraffin/olefin separation, fuel purification such as removal of H 2 O, CO 2 , or SO 2 from low‐grade natural gas, and separation of hexane isomers or xylene mixtures . Recently, there is an increasing demand on capturing environmentally hazardous components from various mixtures of gases or vapors.…”

“…Moreover, the organic ligand component of MOFs allows fine‐tuning of the pore environment with favorable implications on properties . In virtue of such characteristics, MOFs have emerged as a new class of outstanding platform for the adsorption of target mole­cules ranging from gas species to biological molecules . Inspired by these studies, it is reasonable to suppose that boronic acid modified MOFs might be potentially promising for selective recognition and subsequently separation of CDBs.…”

“…Accordingly, we then measured C 6 vapour adsorption at 30 °C and the results were shown in Figure 3e. Ultrahigh n-HEX adsorption capacity up to 209 mg/g was observed, exceeding most top level materials for this task [45][46][47][48][49][50][51][52][53] such as Al-bttotb (151 mg/g), 49 Ca-tcpb (150 mg/g), 48 MIL-53(Fe)-(CF 3 ) 2 (32 mg/g), 47 and Fe 2 (BDP) 3 (113 mg/g) 46 . By contrast, no adsorption and very low adsorption of 10.7 mg/g was observed for the dibranched isomers of 22DMB and 23DMB, owing to MS effect, since the kinetic diameter of dibranched isomers is far larger than the window of [Th 6 Co 2 ] cage.…”

“…In the literature, all reports are focused on the separation of C 6 vapour via multicomponent column breakthrough measurements. [45][46][47][48][49][50][51][52][53] From the viewpoint of saving energy, the direct separation of C 6 isomer from liquid mixture is more desirable, as these C 6 isomers are essentially liquid at room temperature with boiling point more than 58°. In each case, the activated Th-Co-Cage-1 samples were rst immersed in commercially binary mixture.…”
