Structure of protic (HC_nImNTf₂, n = 0-12) and aprotic (C₁C_nImNTf₂, n = 1-12) imidazolium ionic liquids: A vibrational spectroscopic study was written by Moschovi, Anastasia Maria;Dracopoulos, Vassileios. And the article was included in Journal of Molecular Liquids in 2015.Synthetic Route of C11H20N2 This article mentions the following:

The interactions of alkyl substituted imidazolium bis(trifluoromethanesulfonyl)imide protic (PILs) HC_nImNTf₂ (n = 0-12) and aprotic ionic liquids (APILs) C₁C_nNTf₂ (n = 1-12) were studied using vibrational spectroscopy (FT-IR/ATR and FT-Raman). The effect of alkyl substituent length (n = 0-12) on both polar and non-polar regions is elucidated. A sponge like structure is proposed for both systems. The spectral characteristics show that there are certain structural differences between PILs and APILs. The well defined hydrogen bonding in PILs strongly affects the local structure of both the polar head (i.e., induction effect) and the side alkyl chain. The spectral findings tentatively suggest that nanosegregation occurs at shorter alkyl chains. In APILs the data correlated with the polar and non-polar regions are discussed on the basis of the proposed sponge like structure. The trans/cis ratio of the anion conformers is related to the dispersion of the average position of the anion over the cation. Also in the oily phase the local structure of the side chain shows certain differences compared to PIL systems. A tail coupling occurred (up to eight carbon atom alkyls) followed by decoupling in higher length tails in APILs indicating an increase of van der Waals forces between the chains. Moreover, we show that the enthalpy of conformational isomerism of the anion is also a good indicator in the case of APILs, regarding the relative magnitude of these interactions. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Synthetic Route of C11H20N2).

1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Synthetic Route of C11H20N2

Molecular-orbital and structural descriptors in theoretical investigation of electroreduction of nitrodiazoles was written by Kolaric, Branko;Juranic, Ivan;Dumanovic, Dragica. And the article was included in Journal of the Serbian Chemical Society in 2005.SDS of cas: 3034-41-1 This article mentions the following:

It is shown how a simple theor. approach can be used for the investigation of electro-organic reactions. Mononitroimidazoles and mononitropyrazoles were studied by the semiempirical MNDO-PM3 MO method. The electrochem. reduction potentials of diazoles have been correlated with the energy of the LUMO. It was found that an admirable correlation could be obtained by the introduction of simple structural descriptors as a correction to the energy of the LUMO. The interaction of a mol. with its surrounding depends on electrostatic potential and on steric hindrance. Most of these steric effects are taken into account using two parameters having a very limited set of integer values. The first (尾) is the position of a ring substituent regarding ring nitrogens, which accounts for the different orientations of dipole moments and for the different shape of the electrostatic potential. The second (structural) parameter (蟿) is the type of the ring, which accounts mostly for different modes of electrode approach, and for different charge polarization patterns in two diazole rings. The extended correlation with E_LUMO, 尾 and 蟿, is very good, having a regression coefficient r = 0.991. The intrinsic importance of 尾 and 蟿 is exemplified by their high statistical weight In the experiment, the researchers used many compounds, for example, 1-Methyl-4-nitroimidazole (cas: 3034-41-1SDS of cas: 3034-41-1).

1-Methyl-4-nitroimidazole (cas: 3034-41-1) belongs to imidazole derivatives.

Valorization of Sugar Beet Pulp via Torrefaction with a Focus on the Effect of the Preliminary Extraction of Pectins was written by Brachi, Paola;Riianova, Evelina;Miccio, Michele;Miccio, Francesco;Ruoppolo, Giovanna;Chirone, Riccardo. And the article was included in Energy & Fuels in 2017.Synthetic Route of C4H5N3O This article mentions the following:

An agro-industrial residue, i.e., sugar beet pulp, was taken into consideration in this work as a feedstock for valorization as a solid fuel and, potentially, as a source of valuable biochems. obtainable from the torgas condensable fraction. To this end, an exptl. program based on torrefaction of such a residue after pectin extraction (PE-SBP) was performed. The alternative scenario of raw sugar beet pulp (raw-SBP) torrefaction was also investigated for comparison. Raw biomasses and torrefaction products were analyzed by different techniques including thermogravimetric anal. and derivative thermogravimetry (TGA-DTG), Fourier transform IR spectroscopy (FTIR), gas chromatrog. coupled to mass spectrometry (GC/MS), and proximate and ultimate analyses. This allowed the comparative investigation of the role played by the pectin extraction method and the torrefaction temperature on the process performance and main properties of the resulting solid products. Outcomes showed that light torrefaction (200-240 掳C) is a suitable and more energy-efficient process for production of high quality solid fuels from SBP. Moreover, it resulted that PE-SBP is better than raw-SBP as a feedstock due to its lower nitrogen and ash content.

Environmentally Friendly Recycling of Fuel-Cell Membrane Electrode Assemblies by Using Ionic Liquids was written by Balva, Maxime;Legeai, Sophie;Leclerc, Nathalie;Billy, Emmanuel;Meux, Eric. And the article was included in ChemSusChem in 2017.Name: 1-Methyl-1H-imidazol-3-ium chloride This article mentions the following:

The Pt nanoparticles used as the catalyst in proton exchange membrane fuel cells (PEMFCs) represent 鈭?6% of the total price of the cells for a large-scale production, and this is one of the barriers to their commercialization. Therefore, the recycling of the Pt catalyst could be the best alternative to limit the production costs of PEMFCs. The usual recovery routes for spent catalysts containing Pt are pyro-hydrometallurgical processes in which a calcination step is followed by aqua regia treatment, and these processes generate fumes and NO_x emissions, resp. The electrochem. recovery route proposed here is more environmentally friendly, performed under soft temperature conditions, and does not result in any gas emissions. It consists of the coupling of the electrochem. leaching of Pt in chloride-based ionic liquids (ILs), followed by its electrodeposition. The leaching of Pt was studied in pure ILs and in ionic-liquid melts at different temperatures and with different chloride contents.

Despite extensive exptl. work investigating CO2 solubility in many Ionic Liquids (IL), identifying the most appropriate IL for pre-combustion CO2 capture from a techno-economic perspective, remains highly iterative, due to the significant importance of parameters such as mass transfer efficiency and ease of solvent separation, which are often overlooked during exptl. investigations. In this work, a process-based screening method has been developed based on the phys. properties of the ILs, the screening method has four main criteria, namely: 1. Mass transfer, 2. Ease of solvent regeneration, 3. CO2 solubility and 4. H2S solubility Correlations have been developed for each of the four criteria to allow for direct comparison of ILs, and the screening method was used to identify the seven most promising ILs from a database of 295 ILs. The seven ILs where then compared in AspenPlus using a conceptual process containing one absorption, three separation and one compression stage, and a systems anal. was subsequently conducted to compare the ILs using two main criteria, the net power requirement and the cost of CO2 capture. The IL [bmim][NfO] was determined to have the lowest power requirement and lowest CO2 capture cost, whereas [hmim][bti] had the highest values.
