A hybrid monolith incorporated with graphene oxide (GO) was prepared in the first time with binary green porogens of deep eutectic solvents (DESs) and room temperature ionic liquids (RTILs). GO was modified with 3-(trimethoxysilyl) propylmethacrylate (纬-MPS), and the resultant GO-MPS can be incorporated into poly(methacrylic acid-co-butylmethacrylate-coethylene glycol dimethacrylate) monoliths covalently. A hybrid monolithic column with high permeability and homogeneity can be achieved due to good dispersion of GO-MPS in the green solvents. The GO-MPS incorporated monolith was characterized by TEM, SEM, TGA and nitrogen adsorption tests. The separation of small organic mols. of alkylphenones and alkylbenzenes was used to evaluate the performance of GO-MPS grafted monolith. The GO-MPS grafted monolith displayed the maximum column efficiency of 147,000 plates/m, about twice higher than the GO-free monolith. In addition, all of the retention and selectivity of small mols. of alkylphenones and alkylbenzenes increased due to the addition of GO-MPS. The use of DESs and RTILs is a powerful approach for the preparation of GO incorporated polymer monoliths. The monolith was further applied to the separation of tryptic digests from bovine serum albumin, and the result indicated its potential in the anal. of some complex samples.

X-ray structure anal. is also performed to determine the relation between the electrochem. behavior of the ionic liquids, and the formation of intercalated graphitic compounds Two different types of imidazolium cations are studied, specifically the di- and trisubstituted imidazolium. These cations are paired with the following anions: tetrafluoroborate, hexafluorophosphate, bis(trifluoromethanesulfonyl)imide, bis(perfluoroethanesulfonyl)imide, nitrate and H sulfate.

Thermodn. parameters at infinite dilution for thirty-one organic solutes in a series of imidazolyl hydrogen sulfate ionic liquids (ILs) were determined by inverse gas chromatog. (IGC). The IGC characterization was carried out at temperatures ranging between 303.15 and 343.15 K for determining the Hildebrand solubility parameter (未₂) as well as the Flory-Huggins interaction parameter (蠂₁₂^{鈭?/sup>), the activity coefficient at infinite dilution (纬₁₂鈭?/sup>), and the thermodn. functions. In addition, based on the 纬₁₂鈭?/sup> results, the selectivity and capacity were directly calculated for two separation problems (hexane/benzene and hexane/thiophene). Under the different effects of the three ILs, it was found that the values of 蠂₁₂鈭?/sup> and 纬₁₂鈭?/sup> were significantly different for the solutes tested, but all the values follow a certain pattern: they increase with temperature or decrease with temperature As the temperature increased, the solubility parameters of the three ILs showed a linear decrease trend.

Aromatics play essential and unique roles in the areas ranging from synthetic chem. to the manufacturing industry. Production of aromatics from biomass is of great fundamental interest and practical importance to ease the burden of fossil resources. This work delineates a one-step route for the synthesis of renewable aromatics from various biobased furanics and dienophiles by acidic ionic liquids at mild conditions. [Bmim]HSO₄ was used as a catalyst and solvent for the direct conversion of 2,5-dimethylfuran and acrylic acid into p-xylene and 2,5-dimethylbenzoic acid; up to 89% aromatic selectivity was achieved at 87% conversion of 2,5-dimethylfuran at room temperature and atm. pressure, and totally 84% selectivity of p-xylene can be obtained with a subsequent decarboxylation reaction. The reaction mechanism study supplemented with isotopic tracing and DFT calculations revealed the lowest-energy pathway for the two main products. Various starting materials were studied for further extensions of the method, and it turned out that electron-donating Me groups on the furan ring played crucial roles on the activation of dehydration and decarboxylation processes. This work provided convenient access to industrial commodity aromatics from fully biomass-derived feedstocks and thus can be regarded more economically and environmentally feasible.
