“…The selected IL is [Bpy][BF4], a pyridinium‐based IL with good solubility properties in MEA. The [Bpy][BF4] IL has better potential for large‐scale applications than the more famous imidazolium‐based IL due to lower cost, lower toxicity, and environmental benignity . The input conditions given in Table and Table were used to develop the model.…”

This study investigates the process and economic impacts of using an aqueous mixture of 1‐butylpyridinium tetrafluoroborate ([Bpy][BF4]) ionic liquid (IL) and monoethanolamine (MEA) as the solvent for CO2 capture from a coke‐oven plant. The gaps highlighted in the literature on the study of an aqueous mixture of IL and MEA for CO2 capture include lack of detailed process models or information on the impacts of varying the IL concentration on different process conditions and economics. This study addressed these needs by developing a rate‐based, solvent‐based CO2 capture process model with a mixed IL and MEA solvent and using the model to perform process and economic evaluations. The model was developed with Aspen Plus® and was used to investigate seven different aqueous mixtures of IL and MEA. The MEA concentration was 30 wt% for all the seven aqueous solvent mixtures, and the corresponding IL concentration was 0, 5, 10, 15, 20, 25 and 30 wt% for each combination. The hybrid IL solvent mixtures (i.e. 5–30 wt% IL) have 7–9% and 12–27% less regeneration energy and solvent circulation rate respectively compared to the base case (i.e. 30 wt% MEA). Based on a commercial‐scale cost benchmark for the IL, the initial solvent cost for the mixed solution is predictably higher. However, the solvent makeup cost is less for the mixed solvent. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.

A series of low‐cost, pyridinium cation‐based hypergolic ionic liquids (HIL) containing amine, butyl, or allyl substituents with cyanoborohydride [BH3CN]− and dicyanamide [DCA]− anions were developed and characterized. The investigated physicochemical properties include melting and decomposition temperature, viscosity, density, heat of formation (ΔHf) and specific impulse (Isp). The ignition delay (ID) of all HILs was tested with the oxidizer RFNA. The HIL, 1‐allyl 4‐amino pyridinium dicyanamide, exhibited highest density (1.139 g cm−3) amongst the known pyridinium HILs. The heats of formation predicted on the basis of Gaussian 09 suit programs were within the range of − 30 to 356 kJ mol−1. The structure of HIL, 1‐butyl 4‐aminopyridinium cyanoborohydride, was examined by single‐crystal X‐ray diffraction, which revealed hydrogen bonding between anion and cation as N1−H1N⋅⋅⋅N3=2.07 Å, N1−H2N⋅⋅⋅H1B1=2.18 Å, and N1−H2N⋅⋅⋅H2B1=2.21 Å, respectively. HIL (1‐allyl 4‐aminopyridiniun cyanoborohydride) exhibited highest Isp of 228 s amongst the designed series.

In this research, we report a straightforward route for the synthesis of a cationic supramolecular structure via covalently anchoring an ionic liquid-containing pyridinium moiety onto c-methylcalix[4]resorcinarene. Antibacterial activity of the new functionalized c-methylcalix[4]resorcinarene was evaluated against Gram-positive and Gram-negative bacteria. Surprisingly, this compound exhibited a selective antibacterial effect on Gram-positive bacteria, which is very important from the industrial and medicinal point of view. These preliminary results are attractive for the development of a new antibacterial agent. Electronic supplementary material The online version of this article (
