The properties of ionic liquid plus acetone or acetonitrile mixtures were studied from the macro and microscopic levels by the measurement of relevant thermophys. properties and through mol. modeling studies. The liquid mixtures were considered in the whole composition range and analyzed in terms of possible hydrogen bonding between the ions and ions with the mol. solvents. The reported results show how the large non-ideality of these systems stands on the high affinity of acetone and acetonitrile for the imidazolium hydrogen bond donor sites, which allow competition with the corresponding anions for these sites specially but not limited to mol. solvent rich mixtures The reported results allow to quantify the relevance of hydrogen bonding for the properties of ionic liquid – mol. solvent mixtures, which can be fine-tuned through the amounts of cosolvent present in the mixture as a mechanism to control mixed fluids organization. In addition to this study using 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate, there are many other studies that have used 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6Recommanded Product: 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate) was used in this study.

《Controlling the nanoscale friction by layered ionic liquid films》 was written by An, Rong; Qiu, Xiuhua; Shah, Faiz Ullah; Riehemann, Kristina; Fuchs, Harald. COA of Formula: C8H15BF4N2 And the article was included in Physical Chemistry Chemical Physics in 2020. The article conveys some information:

The nanofriction coefficient of ionic liquids (ILs), 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]) and 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF6]), on the surfaces of mica and graphite was investigated using at. force microscopy (AFM). A pronounced layered spatial distribution was found in the IL film formed on the solid substrates and can be divided into 3 well distinguishable regions exhibiting different phys. properties with increasing distance from the substrate. We found that the friction coefficient (μ) increases monotonically as the layering thickness decreases, no matter what the thickness of the bulk IL is. This suggests that the layering assembled IL at solid surfaces is more important than the bulk phase in determining the magnitude of the nanoscale friction. The increase in the friction coefficient as the layering thickness decreases is most likely attributed to the assembled ordered IL layers closer to the substrate surfaces having a greater activation barrier for unlocking the surfaces to allow shear. In the experimental materials used by the author, we found 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6COA of Formula: C8H15BF4N2)

3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6) is a member of lonic liquids. A multidisciplinary study on lonic liquids is emerging, including chemistry, materials science, chemical engineering, and environmental science. More specifically, some important fundamental viewpoints are now different from the original concepts, as insights into the nature of lonic liquids become deeper. For example, the physicochemical properties of lonic liquids are now recognized as ranging broadly from the oft quoted “nonvolatile, non-flammable, and air and water stable” to those that are distinctly volatile, flammable, and unstable.

Application In Synthesis of 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborateIn 2019 ,《Using an ionic liquid to reduce the electrical percolation threshold in biobased thermoplastic polyurethane/graphene nanocomposites》 appeared in Polymers (Basel, Switzerland). The author of the article were Aranburu, Nora; Otaegi, Itziar; Guerrica-Echevarria, Gonzalo. The article conveys some information:

Biobased thermoplastic polyurethane (bTPU)/unmodified graphene (GR) nanocomposites (NCs) were obtained by melt-mixing in a lab-scaled conventional twin-screw extruder. Alternatively, GR was also modified with an ionic liquid (GR-IL) using a simple preparation method with the aim of improving the dispersion level. XRD diffractograms indicated a minor presence of well-ordered structures in both bTPU/GR and bTPU/GR-IL NCs, which also showed, as observed by TEM, nonuniform dispersion. Elec. conductivity measurements pointed to an improved dispersion level when GR was modified with the IL, because the bTPU/GR-IL NCs showed a significantly lower elec. percolation threshold (1.99 wt%) than the bTPU/GR NCs (3.21 wt%), as well as higher conductivity values. Young’s modulus increased upon the addition of the GR (by 65% with 4 wt%), as did the yield strength, while the ductile nature of the bTPU matrix maintained in all the compositions, with elongation at break values above 200%. This pos. effect on the mech. properties caused by the addition of GR maintained or slightly increased when GR-IL was used, pointing to the success of this method of modifying the nanofiller to obtain bTPU/GR NCs. In addition to this study using 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate, there are many other studies that have used 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6Application In Synthesis of 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate) was used in this study.

HPLC of Formula: 174501-65-6In 2021 ,《Surface charge density in electrical double layer capacitors with nanoscale cathode-anode separation》 was published in Journal of Physical Chemistry B. The article was written by Qing, Leying; Zhao, Shuangliang; Wang, Zhen-Gang. The article contains the following contents:

Using a dynamic d. functional theory, we study the charging dynamics, the final equilibrium structure, and the energy storage in an elec. double layer capacitor with nanoscale cathode-anode separation in a slit geometry. We derive a simple expression for the surface charge d. that naturally separates the effects of the charge polarization due to the ions from those due to the polarization of the dielec. medium and allows a more intuitive understanding of how the ion distribution within the cell affects the surface charge d. We find that charge neutrality in the half-cell does not hold during the dynamic charging process for any cathode-anode separation, and also does not hold at the final equilibrium state for small separations Therefore, the charge accumulation in the half-cell in general does not equal the surface charge d. The relationships between the surface charge d. and the charge accumulation within the half-cell are systematically investigated by tuning the electrolyte concentration, cathode-anode separation, and applied voltage. For high electrolyte concentrations, we observe charge inversion at which the charge accumulation exceeds the surface charge at special values of the separation In addition, we find that the energy d. has a maximum at intermediate electrolyte concentrations for a high applied voltage.

And the article was published in Journal of Molecular Liquids in 2019. COA of Formula: C8H15BF4N2 The author mentioned the following in the article:

The water sorption behavior of representative pyridinium-based ionic liquid (IL), 1-hexylpyridinium hexafluorophosphate ([C6Py][PF6]), was studied over the whole range of the water activity a using a continuous gravimetric method. The anal. of the water sorption isotherm using the combination of a two-mode sorption (i.e. Henry-clustering) allowed to better understand [C6Py][PF6]-water interactions. At low and intermediate activity (a ≤ 0.8), the water mols. revealed a very low affinity to [C6Py][PF6] and, consequently, the water uptake was rather low. On the contrary, at high water activity (a > 0.8), the water uptake increased exponentially and the water clustering easily occurred. The constant of the Henry-clustering equation as well as the water clustering mechanism in [C6Py][PF6] were discussed and compared to those of imidazolium-based ILs: 1-hexyl-3-methylimidazolium hexafluorophosphate [C6C1i.m.][PF6] (water-immiscible IL) and 1-butyl-3-methylimidazolium tetrafluoroborate [C4C1i.m.][BF4] (water-miscible IL). It is shown that the sorption of water mols. by pyridinium-based ILs is controlled not only by the anion’s nature, but also by the cation’s nature. Moreover, the Zimm-Lundberg theory was used to determine the water mean cluster size (MCS) in [C6Py][PF6], [C6C1i.m.][PF6] and [C4C1i.m.][BF4]. The MCS results confirmed the strong capacity of water mols. to be aggregated in [C6Py][PF6]. In order to have a deeper insight into the water mol. state, IR spectroscopy measurements were carried out as a function of the relative humidity value and the obtained results were correlated with the results of water sorption isotherms. It is found that at high water activity (a > 0.8), sorbed water mols. are strongly linked with ILs by hydrogen bonds and, therefore, are easily aggregated. The results came from multiple reactions, including the reaction of 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6COA of Formula: C8H15BF4N2)

SDS of cas: 174501-65-6In 2019 ,《Nonbonding interaction analyses on PVDF/[BMIM][BF4] complex system in gas and solution phase》 appeared in Journal of Molecular Modeling. The author of the article were Sarkar, Ranjini; Kundu, T. K.. The article conveys some information:

The present study provides a detailed quantum chem. description of the physicochem. interactions between poly-vinylidene fluoride (PVDF) and 1-butyl-3-methyl-imidazolium tetrafluoro borate ([BMIM][BF4]) ionic liquid (IL). Geometry optimization and frequency calculations are carried out for four monomer units of α- and β-PVDF, [BMIM][BF4], and PVDF/[BMIM][BF4] using dispersion corrected d. functional theory. The effects of solvation on the systems under study are demonstrated for three polar aprotic solvents, namely tetra-hydrofuran (THF), acetone, and n,n-DMF (DMF) using the integral equation formalism polarizable continuum model (IEFPCM). Calculated neg. solvation free energy values suggest solution phase stability of the systems under study. Binding and interaction energies for β-PVDF/IL are found higher in magnitude than those for α-PVDF/IL. The nonbonding interaction phenomenon of β-PVDF/[BMIM][BF4] is elucidated on the basis of natural bond orbital (NBO), Bader’s quantum theory of atoms in mols. (QTAIM), delocalization indexes, Hirshfeld surface, and reduced d. gradient (RDG) analyses. Both anions and cations of ionic liquids are found to show weak van der Waals interaction with PVDF mol. but the anion ([BF4]-)/PVDF interaction is found to be stronger than cation ([BMIM]+)/PVDF interaction. Inter-unit C-H···F type hydrogen bonds are found to show improper (causing blue shifts in vibrational frequencies) nature. Frontier MO anal. is carried out, and different chem. parameters like electronegativity, chem. potential, chem. hardness and softness, and electrophilicity index are calculated using Koopmans’ theorem. Thermochem. calculations are also performed, and the variation in different standard thermodn. parameters with temperature is formulated.

《Ultrafast Hydrogen Bond Exchanging between Water and Anions in Concentrated Ionic Liquid Aqueous Solutions》 was written by Wei, Qianshun; Zhang, Miaomiao; Zhou, Dexia; Li, Xiaoqian; Bian, Hongtao; Fang, Yu. Synthetic Route of C8H15BF4N2This research focused onultrafast hydrogen bond exchange water anion ionic liquid. The article conveys some information:

The mixtures of 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BF4) ionic liquids (ILs) and water as a function of IL concentrations have been investigated by Fourier transform IR (FTIR) spectroscopy and ultrafast two-dimensional IR (2D IR) spectroscopy. FTIR spectra of the mixtures resolve two different types of water species, one interacting with the BF4- anions and the other associated with bulklike water mols. These two water species are in a dynamic equilibrium through forming different hydrogen bonding configurations which are separated by more than 100 cm-1 in the IR spectra. The structural dynamics of the IL mixtures are further revealed by monitoring the vibrational relaxation dynamics of the OD stretching group of interfacial water mols. hydrogen bonded to BF4- anions. With the increase of the IL bulk concentration, vibrational population and rotational dynamics of the interfacial water mols. can be described by a biexponential decay function and are strongly dependent on the IL concentrations Furthermore, the ultrafast hydrogen bond exchanging between water and BF4- anions in the ILs are also measured using 2D IR spectroscopy. The average hydrogen bond exchanging rate is determined to be 19 ± 4 ps, which is around 3 times slower than that in the NaBF4 electrolyte aqueous solution The much slower hydrogen bond exchanging rate indicates that the local structure of ILs and water mols. are strongly mediated by the steric effect of the cationic group in the ILs, which is proposed to be responsible for the formation of the heterogeneous structure in the IL mixtures By using SCN- as the anionic probe, the structural inhomogeneity in the IL solutions can be confirmed from the distinct rotational dynamics of the SCN-, which is segregated from the rotational dynamics of water mols. in the IL mixtures The results came from multiple reactions, including the reaction of 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6Synthetic Route of C8H15BF4N2)

In 2019,Journal of Molecular Liquids included an article by Kaneko, Kazuyoshi; Mori, Takahiro; Hattori, Shuji; Takekiyo, Takahiro; Masuda, Yuichi; Yoshimura, Yukihiro; Shimizu, Akio. COA of Formula: C8H15BF4N2. The article was titled 《Dynamic and static properties of mixtures of 1-butyl-3-methylimidazolium tetrafluoroborate and alcohols with various alkyl chain lengths》. The information in the text is summarized as follows:

The dynamic and static properties of mixtures of 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]) and alcs. with various alkyl chain lengths were investigated. For alc. concentrations of 20 mol% or less, where the alc./ionic liquid system maintains a nano-heterogeneous structure, the self-diffusion coefficient and the chem. shift of anions and cations in the alc./[BMIM][BF4] system were not dependent on the alkyl chain length of the alc., but were almost coincident with each other when comparing the same solvent concentration This indicates that the solution structure of pure [BMIM][BF4] was almost maintained in the alc./ionic liquid system. Moreover, alc. having short alkyl chain length and water moved clearly faster than the IL, but the movement of alc. having long alkyl chain length moved close to that of the IL suggesting that the alcs. may not be able to move significantly in the IL. In the part of experimental materials, we found many familiar compounds, such as 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6COA of Formula: C8H15BF4N2)

The author of 《Experimental and computational investigation of methane hydrate inhibition in the presence of amino acids and ionic liquids》 were Lee, Dongyoung; Go, Woojin; Seo, Yongwon. And the article was published in Energy (Oxford, United Kingdom) in 2019. Category: imidazoles-derivatives The author mentioned the following in the article:

Amino acids (glycine and alanine) and ionic liquids ([BMIM][BF4] and [BMIM][I]) were examined for their inhibition elects on CH4 hydrates with exptl. and computational approaches. Both amino acids and ionic liquids functioned well as thermodn. hydrate inhibitors, by shifting equilibrium curves of CH4 hydrates toward harsh conditions. However, powder X-ray diffraction patterns indicated that amino acids and ionic liquids did not alect the hydrate structure because they were not included in the hydrate cages due to their large mol. size. Gas uptake measurements showed that the conversion of water into gas hydrates and the formation rates of CH4 hydrate were significantly influenced by inhibitors. D. functional theory calculations indicated that [BMIM][BF4] had a larger potential than glycine to inhibit gas hydrate formation by giving a more neg. interaction energy between a cage and an inhibitor mol. The time-dependent Raman spectra collected during CH4 hydrate formation demonstrated that [BMIM][BF4] hindered CH4 mols. from occupying small (512) cages, whereas glycine had a strong influence on large (51262) cages of sI hydrates. The exptl. and computational results provide a better understanding of inhibition mechanisms of gas hydrates and thus can contribute to the improved control of hydrate formation in oil and gas pipelines.

The article conveys some information:

Stretchable ionogels have recently emerged as promising soft and safe ionic conductive materials for use in wearable and stretchable electrochem. devices. However, the complex preparation process and insufficient thermomech. stability greatly limit the precise rapid fabrication and application of stretchable ionogels. Here, we report an in situ 3D printing method for fabricating high-performance single network chem. ionogels as advanced strain sensors. The ionogels consist of a special crosslinking network constructed by poly(ionic liquid) and hyperbranched polymer (macro-crosslinkers) that exhibits high stretchability (>1000%), superior room-temperature ionic conductivity (up to 5.8 mS/cm), and excellent thermomech. stability (-75 to 250°C). The strain sensors based on ionogels have a low response time (200 ms), high sensitivity with temperature independence, long-term durability (2000 cycles), and excellent temperature tolerance (-60 to 250°C) and can be used as human motion sensors. This work provides a new strategy to design highly stretchable and superior stable electronic devices. In the experiment, the researchers used 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6Reference of 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate)
