“…The most promising separation method for these molecules has been shown to be enclathration, however isomer recovery usually leads to byproduct formation 11. In this regard, Barbour and Lusi have recently shown that a single Ni‐based clathrate may be used to neatly separate the xylene isomers in the vapor phase 12…”

A supramolecular crystallization-based approach has been developed for the shape-dependent separation of geometrical isomers under near-ambient conditions. Difficulties to separate such isomers arise because of their very similar physical properties. The present approach relies on the ability of C 60 to preferentially form solvate crystals with molecules of a specific geometry. Subsequently, these molecules are released upon mild heating to regenerate pure C 60 . By taking isomers of xylene and trimethylbenzene (TMB) as examples, we show that one of the isomers can be extracted from the rest with very high purity. To separate TMB isomers, a new C 60 -1,3,5-TMB solvate was developed, which led to the isolation of isomer purities greater than 99.6 %. Versatility, a low operating temperature of approximately 100 8C, a separation efficiency of more than 10 weight % of C 60 per cycle, and reagent recyclability makes this a promising molecular shape-sorting approach.

“…In molecular crystals, intricate equilibria are known to exist between the pure compounds and their hydrogen-bonded water and alcohol solvates (Braga et al, 2008;Braun et al, 2012). Similarly, ammonia and hydrohalic acids can reversibly coordinate to metals in discrete (Mínguez Espallargas et al, 2007) and polymeric complexes (Adams et al, 2007), while clathration of aromatic species can be driven by the increased lattice energy deriving from weak van der Waals interactions (Lusi & Barbour, 2012). Even the simple selective exposure of a given crystallographic face to water vapour can trigger molecular reorientation (Jiang et al, 2013).…”

Reactions in the solid state are at the core of crystal engineering as they can result in new crystalline phases that are not always accessible by traditional solution methods. The work of Brammer and co-workers [Wright et al . (2015), IUCrJ , 2 , 188–197] represents a clear example of this potential as applied to the synthesis of a silver–phenazine coordination polymer.

“…Xylene isomers separation has attracted highly attention over the world as a result of similar physicochemical properties of these isomers. Various methods for Xylene separation have been applied such as distillation [1], fractional crystallization [2] and adsorption [3]. The latest method has been most used as alternatives in industrial process for the separation [4].…”

Carbon nanotubes (CNTs) have been considered as an excellent adsorbent in environmental engineering, especially for treatment of volatile organic compounds (VOCs). The paper presents a new approach for the selective adsorption of Xylene isomers from air samples using nanomaterial based on oxidized multiwalled carbon nanotubes. In the first study, the functionalization of two oxidized MWCNTs was achieved with hydrogen peroxide and sodium hypochlorite. The characterization of functionalized CNTs (CNT-NaOCl, CNT-H2O2) was performed by Fourier transform infrared spectroscopy (FT-IR) and X-Ray diffractometer (XRD). Afterthat, the applications of pristine CNTs and oxidized CNTs for removal of three Xylene isomers from air samples were discussed. The results demonstrate that the correlation of CNTs and three isomers was significantly different with an affinity order o-Xylene > m-Xylene > p-Xylene. The oxidized CNTs with carbonyl groups increased significantly its adsorption capacity for these isomers. A comparison in term of adsorption performance shows that the framework distinguishes among these adsorbents due to the dispersive properties and the electrostatic interaction between the Xylene isomers and oxidized CNTs surface.
