  • Dialkoxy functionalized quaternary ammonium ionic liquids as potential electrolytes and cellulose solvents

    A series of new ionic liquids, based on dialkoxy-functionalized quaternary ammonium cations side chains: 1 = CH3, 1O1 = CH3OCH2, 1O2 = CH3OC2H4, 2O2 = C2H5OC2H4; cations: [N11,1O1,1O2], [N11,1O1,2O2], [N11,1O2,1O2], [N11,1O2,2O2] and [N11,2O2,2O2]}, with BF4−, (CF3SO2)2N− (NTf2) and CH3CO2− (OAc) as counteranions, have been prepared and characterized. Their basic properties, such as spectroscopic characteristics, melting point, glass transition temperature, thermal stability, electrochemical window, density, refractive index, viscosity and conductivity, were measured and comparatively studied. The incorporation of two flexible alkoxy chains makes the quaternary ammonium salts highly qualified to be low-viscous and high-conductive room temperature ILs, and even some of them have significantly better fluidity than the popular imidazolium ILs with a similar molecular weight, e.g.[N11,1O1,2O2]BF4 (151 cP and 2.11 mS cm−1, Mw: 249) vs.[HMIm]BF4 (220 cP and 1.2 mS cm−1, Mw: 256) at 25 °C. The electrochemical windows of these ILs were evaluated up to 5.5 V. In addition, the dialkoxy OAc ILs were found to have excellent solvent power for cellulose under mild conditions, e.g. a solution of 18 wt% microcrystalline cellulose in [N11,2O2,2O2]OAc at 80 °C. By precipitation with water, the dissolved cellulose (I crystal structure) was regenerated as nanosized cellulose II particles with increased surface area and decreased crystallinity, determined by FE-SEM and XRD.

  • Carborane‐Derivatized Low‐Melting Salts with Ether‐Functionalized Cations – Preparation and Properties

    AbstractA new series of low‐melting ammonium salts based on the [nido‐7,8‐C2B9H12] anion have been synthesized and characterized, and their physicochemical properties including spectroscopic properties, thermal properties, surface properties, solubility, density, viscosity, electrochemical properties, and tribological properties have been studied in detail. In comparison with previously reported carborane‐derivatized imidazolium or pyridinium salts, these diether‐functionalized ammonium salts display lower phase transition temperatures (Tg = –76 to –57 °C), and four exist as liquids at room temperature due to their flexible alkoxy chains. TGA analysis revealed that the weight loss rates of these carborane‐derivatized low‐melting salts were ca. 30–80 wt.‐% after thermal decomposition, which is different from the traditional RTILs. SEM images showed that the resulting residue had hollow reticular shell morphology, and XPS and XRD analyses indicate that the main components of the skeleton are B2O3 and amorphous carbon. This provides a new strategy for preparing new inorganic porous materials by thermal decomposition of these low‐melting salts.
