Synthesis of Controllable Imidazole Based Partly Ionic-Liquid Polymers

CO2 absorption of polymers of ammonium-based ionic liquid monomers

The topic of global warming as a result of increased atomospheric CO2 concentration is becoming the most important environmental issue that the world faces today.[1] The capture and separation of CO2, especially CO2 from large point source, for example, fossil-fuel-fired electrical power–generation plants is critical to stabilize the atomospheric CO2 concentration.[2] The existing commercial CO...

Nonlinear capacitance and electrochemical response of ionic liquid-ionic polymers

Ionic Liquid Solvation versus Catalysis: Computational Insight from a Multisubstituted Imidazole Synthesis in [Et2NH2][HSO4]

The mechanisms of a tetrasubstituted imidazole [2-(2,4,5-triphenyl-1 H-imidazol-1-yl)ethan-1-ol] synthesis from benzil, benzaldehyde, ammonium acetate, and ethanolamine in [Et2NH2][HSO4] ionic liquid (IL) are studied computationally. The effects of the presence of the cationic and anionic components of the IL on transition states and intermediate structures, acting as a solvent versus as a cata...

Lactic-based Novel Amine Ionic Liquid: Synthesis and Characterization of [DEA][Lac]

In this study, a novel amine ionic liquid “Diethanolamine Lactic” [DEA][Lac] was synthesized. The replacement of halogenated ion fluid was used as a modified methodology for the preparation of diethanolamine based on lactic acid. The ionic liquid was characterized using the Fourier transform infrared (FTIR) spectra and the nuclear magnetic resonance (NMR) spectroscopy. The changes in bands' wav...

Ignition Evaluation of Monopropellant Blends of HAN and Imidazole-Based Ionic Liquid Fuels

Potential dual-mode monopropellant/electrospray capable binary mixtures of hydroxyl ammonium nitrate with ionic liquid fuels [Bmim][NO3] and [Emim][EtSO4] are synthesized and tested for monopropellant ignition capability in a micro reactor setup. The setup is benchmarked using 30% hydrogen peroxide solution decomposed via silver catalyst. Results show similar trends, but variance in the quantit...
