“…This result is further supported by TGA which is featureless until decomposition, indicating that no water was absorbed. Similar results have been reported using a square-grid Cd(II) MOF [21] and a lanthanide-carboxylate-MOF [22]. Figure 6 shows the PXRD traces of the resultant alcohol inclusion compounds.…”

Abstract. The solvothermal reaction of 3-(4-pyridyl)benzoic acid and zinc nitrate yielded a 2D network with an sql topology. Both elemental analysis and single crystal X-ray diffraction studies confirmed the formula of the compound as {[Zn(34pba) 2 ] Á (0.5 DMF) Á (0.5 H 2 O)} n (1). At room temperature, the desolvated phase of 1, 1d, absorbs methanol, ethanol, 1-propanol and 1-butanol but not water vapour.

“…Thus adsorption capacity is mainly attributed to the micropores in the adsorbents. This is logical, as the kinetic diameter of butanol is 0.5 nm [45], and micropores (smaller than 2 nm) provide a more stable environment to store butanol molecules. Desorption TCD profiles of unmodified AC and AC treated with 10% H 2 O 2 were obtained via programmed temperature ramping.…”

a b s t r a c tButanol is considered a promising, infrastructure-compatible biofuel. Unfortunately, the fermentation pathway for butanol production is restricted by its toxicity to the microbial strains used in the process. Gas stripping technology can efficiently remove butanol from the fermentation broth as it is produced, thereby decreasing its inhibitory effects. Adsorption can then be used to recover butanol from the vapor phase. Active carbon samples and zeolite were investigated for their butanol vapor adsorption capacities. Commercial activated carbon was modified via hydrothermal H 2 O 2 treatment, and the specific surface area and oxygen-containing functional groups of activated carbon were tested before and after treatment. Hydrothermal H 2 O 2 modification increased the surface oxygen content, Brunauer-Emmett-Teller surface area, micropore volume, and total pore volume of active carbon. The adsorption capacities of these active carbon samples were almost three times that of zeolite. However, the un-modified active carbon had the highest adsorption capacity for butanol vapor (259.6 mg g −1 ), compared to 222.4 mg g −1 after 10% H 2 O 2 hydrothermal treatment. Both modified and un-modified active carbon can be easily regenerated for repeatable adsorption by heating to 150 • C. Therefore, surface oxygen groups significantly reduced the adsorption capacity of active carbons for butanol vapor.

“…14c and d demonstrate that water-1-propanol and water-2-propanol mixtures of azeotropic compositions can be separated with Co(pbdc). Analogous water-selective separations of water-alcohol mixtures are possible with CID-1, 34 Cu-GLA, 35 Zn(II)-MOF, 36,37 and JUC-110; 38 detailed analyses are provided in the ESI. †…”

We examine mixture separations with microporous adsorbents such as zeolites, metal-organic frameworks (MOFs) and zeolitic imidazolate frameworks (ZIFs), operating under conditions close to pore saturation. Pore saturation is realized, for example, when separating bulk liquid phase mixtures of polar compounds such as water, alcohols and ketones. For the operating conditions used in industrial practice, pore saturation is also attained in separations of hydrocarbon mixtures such as xylene isomers and hexane isomers. Separations under pore saturation conditions are strongly influenced by differences in the saturation capacities of the constituent species; the adsorption is often in favor of the component with the higher saturation capacity.Effective separations are achieved by exploiting differences in the efficiency with which molecules pack within the ordered crystalline porous materials. For mixtures of chain alcohols, the shorter alcohol can be preferentially adsorbed because of its higher saturation capacity. With hydrophilic adsorbents, water can be selectively adsorbed from water-alcohol mixtures. For separations of o-xylene-m-xylene-p-xylene mixtures, the pore dimensions of MOFs can be tailored in such a manner as to allow optimal packing of the isomer that needs to be adsorbed preferentially. Subtle configurational differences between linear and branched alkane isomers result in significantly different packing efficiencies within the pore topology of MFI, AFI, ATS, and CFI zeolites. A common characteristic feature of most separations that are reliant on molecular packing effects is that adsorption and intra-crystalline diffusion are synergistic; this enhances the separation efficiencies in fixed bed adsorbers.
