Abstract: Recently developed MOF surface-coating techniques, the controlled SBU approach (CSA) for the generation of MOF-5, and the use of self-assembled monolayers have been combined to generate a wall-bonded, crosslinked stationary phase for gas chromatographic capillary columns displaying excellent performance in the separation of natural gas components. The chromatographic performance of this new type of column has been compared to the state-of-the-art solution for this separation problem, namely a coated silica col… Show more

“…Interestingly, butane, propane, propene, and methanol were adsorbed in decreasing order, whereas the remaining compounds were not adsorbed. This shows that this MOF can separate normal C 2 , C 3 , and C 4 , from branched alkanes and normal hydrocarbons above C 4 64. Molecular simulations also showed that about 40 % more cis ‐2‐butene than trans ‐2‐butene would fit into the cages.…”

“…The commercial column required 0.13 min longer and the distribution of peaks was nonuniform. To demonstrate the separation power of the MOF‐5‐CSA column, additional C 4 components were added to the natural gas samples 64. The results showed that even different butene isomers were easily baseline separated, despite their similar vapor pressures and small amounts.…”

“…相同的保留 顺序也表现在 MIL-101 [35] 分离 C 5 ~C 13 烷烃. 但相比于 MOF-5 [25] (1 min), 这两种材料的分离时间较长, 这可能 与 MOFs 材料本身的特征有关系 [29] . Figure 1 Chromatograms of alkane mixtures separated on a MOF-508 column [23] : (A) separation of n-pentane and n-hexane, (B) separation of 2-methylbutane and n-pentane, (C) separation of 2,2-dimethylbutane, 2-methylpentane, and n-hexane, and (D) separation of an alkane mixture containing 2-methylbutane (1), n-pentane (2), 2,2-dimethylbutane (3), 2-methylpentane (4), and n-hexane (5 35,46] .…”

MOF-CJ3 在分离二氯苯、溴氰 苯、氯硝基苯和硝基甲苯时, 主要是根据分析物与 MOFs 内壁之间的范德华相互作用力, 依照沸点的顺序 洗脱, 而其在分离甲酚和对苯二酚同分异构体时, 由于 羟基(-OH)和甲基(-CH 3 )的共同影响, 保留顺序分别为 对甲苯酚<间甲苯酚<邻甲苯酚和邻苯二酚<对苯二 酚<间苯二酚 [27] .…”
