And the article was included in Journal of Solid State Chemistry in 2019.Application In Synthesis of 1-Methyl-3-propylimidazolium Chloride This article mentions the following:

The ionothermal reaction of EuCl₃ with 4,4′-biphenyldicarboxylic acid (H₂BPDC) produced a 3-dimensional fluorescence coordination polymer (CP), [PMI]₂[Eu₂(BPDC)₃Cl₂] (1). 1 Was dispersed onto the bandage, and further infiltrated by polyvinylidene fluoride (PVDF) to give a mixed matrix 1@PVDF/bandage composite film (1-film).

Determination of Missing Crystal Structures in the 1 Alkyl-3-methylimidazolium Hexafluorophosphate Series: Implications on Structure-Property Relationships was written by Endo, Takatsugu;Masu, Hyuma;Fujii, Kozo;Morita, Takeshi;Seki, Hiroko;Sen, Sabyasachi;Nishikawa, Keiko. And the article was included in Crystal Growth & Design in 2013.Electric Literature of C7H13ClN2 This article mentions the following:

The authors have performed single crystal X-ray diffraction analyses of two 1-alkyl-3-methylimidazolium hexafluorophosphate ([C_nmim]-PF₆) salts, [C₁mim]-PF₆, and [C₃mim]-PF₆. The thermodynamically metastable crystalline phase (尾 phase) of the former was obtained by crystallization from the melt in a capillary for the crystallog. anal. Both the cation and the anion in the 尾 phase of [C₁mim]-PF₆ show higher point group symmetry than those in the stable 伪 phase. This result is shown to be consistent with the fact that the m.p. of the 尾 polymorph (314 K) is significantly lower than that of the 伪 polymorph (364 K). The crystal structure of [C₃mim]-PF₆ seems to be typical of that characteristic of the crystals of imidazolium-based room temperature ionic liquids The cation conformation is the one in between those characteristic of the crystal structures of [C₂mim]-PF₆ and [C₄mim]-PF₆. When taken together, all crystallog. data for the [C_nmim]-PF₆ series (n = 1-4) demonstrate the influence of the alkyl chain length dependence on structural packing in these salts. The free volume fractions for these structures are calculated and compared to the lattice energy simply based on formula unit volume It is shown that the difference in the alkyl chain length of the imidazolium cations does not monotonically change with the lattice energy of the crystal structure, and the latter also depends on the packing efficiency of the constituent ions in the structure.

Nanocage formation and structural anomalies in imidazolium ionic liquid glasses governed by alkyl chains of cations was written by Bakulina, Olga D.;Ivanov, Mikhail Yu.;Prikhod’ko, Sergey A.;Pylaeva, Svetlana;Zaytseva, Irina V.;Surovtsev, Nikolay V.;Adonin, Nicolay Yu.;Fedin, Matvey V.. And the article was included in Nanoscale in 2020.Synthetic Route of C7H13ClN2 This article mentions the following:

Intriguing nanostructuring anomalies have been recently observed in imidazolium ionic liquids (ILs) near their glass transition points, where local d. around a nanocaged solute progressively grows up with temperature Herewith, we for the first time demonstrate exptl. and theor., that these anomalies are governed by alkyl chains of cations and crucially depend on their length. ESR spectroscopy on a series of ILs [C_nmim]BF₄ (n = 0-12) shows that only the chains with n = 3-10 favor anomaly. Moreover, remarkable even vs. odd n peculiarities were systematically observed Finally, similar anomaly was for the first time observed for a non-IL glass of di-Bu phthalate, which structurally mimics cations of imidazolium ILs. Therefore, such anomalous d. behavior in a glassy state nanocage goes far beyond ILs and proves to be a more general phenomenon, which can be structurally tuned and rationally adjusted for various potential applications in nanoscale materials.

Extended dissolution studies of cellulose in imidazolium based ionic liquids was written by Vitz, Juergen;Erdmenger, Tina;Haensch, Claudia;Schubert, Ulrich S.. And the article was included in Green Chemistry in 2009.Category: imidazoles-derivatives This article mentions the following:

Ionic liquids (ILs) have become advantageous solvents for the dissolution and homogeneous processing of cellulose in recent years. However, despite significant efforts, only a few ILs are known for their capability to efficiently dissolve cellulose. In order to overcome this limitation, we screened a wide range of potentially suitable ILs. From our studies, some remarkable results were obtained, for example, an odd-even effect was found for different alkyl side-chain lengths of the imidazolium chlorides which could not be observed for the bromides. Furthermore, 1-ethyl-3-methylimidazolium di-Et phosphate was found to be best suitable for the dissolution of cellulose; dissolution under microwave irradiation resulted in almost no color change. No degradation of cellulose could be observed In addition, 1-ethyl-3-methylimidazolium di-Et phosphate has a low m.p. which makes the viscosity of the cellulose solution lower and, thus, easier to handle. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Category: imidazoles-derivatives).

And the article was included in Chemistry – A European Journal in 2004.Reference of 79917-89-8 This article mentions the following:

Twenty two hydrophobic ionic liquids, 1-alkyl(alkyl ether)-3-methylimidazolium ([C_mmim]⁺ or [C_mO_nmim]⁺; where C_m is 1-alkyl, C_m = nC_mH_2m+1, m = 1-4 and 6; C_mO_n is 1-alkyl ether, C₂O₁ = CH₃OCH₂, C₃O₁ = CH₃OCH₂CH₂, and C₅O₂ = CH₃(OCH₂CH₂)₂) perfluoroalkyltrifluoroborate ([R_FBF₃]^–, R_F = CF₃, C₂F₅, nC₃F₇, nC₄F₉), were prepared and characterized. Some of the important physicochem. properties of these salts including m.p., glass transition, viscosity, d., ionic conductivity, thermal and electrochem. stability, were determined and were compared with those of the reported [BF₄]^–-based ones. The influence of the structure variation in the imidazolium cation and the perfluoroalkyltrifluoroborate ([R_FBF₃]^–) anion on the above physicochem. properties is discussed.

Use of ab Initio Calculations toward the Rational Design of Room Temperature Ionic Liquids was written by Turner, Elizabeth A.;Pye, Cory C.;Singer, Robert D.. And the article was included in Journal of Physical Chemistry A in 2003.Category: imidazoles-derivatives This article mentions the following:

Ionic liquids are gaining substantial interest as alternative reaction media. Despite the overwhelming amount of evidence suggesting a relation between their structure and m.p., there still remains the problem of selectively choosing a particular ionic pair that will produce a liquid at room temperature Ionic liquids based on 1-alkyl-3-methylimidazolium halides were studied using ab initio calculations using Gaussian 98 and the 6-31G^* and 6-31+G^* basis sets. The calculated interaction energy increases in magnitude with decreasing alkyl chain length at the Hartree-Fock level, although no trend was found to exist with increasing anionic radius. Correlations between m.p. and interaction energy were studied. Linear trends exist in the 1-n-butyl-3-methylimidazolium (Bmim) halide series as well as the 1-alkyl-3-methylimidazolium iodide series. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Category: imidazoles-derivatives).

Effect of Alkyl Chain Length on Derived Thermodynamic Properties of 1-Alkyl-3-methylimidizolium Chloride Ionic Liquids and Their Mixtures with Ethanol was written by McCorkill, Mary E.;Dickmann, James S.;Kiran, Erdogan. And the article was included in Industrial & Engineering Chemistry Research in 2019.Quality Control of 1-Methyl-3-propylimidazolium Chloride This article mentions the following:

Densities of the ionic liquids [C₂C₁i.m.]Cl, [C₃C₁i.m.]Cl, [C₄C₁i.m.]Cl, and [C₆C₁i.m.]Cl and their mixtures with EtOH were determined up to 40 MPa and 398 K. D. was modeled as a function of temperature, pressure, and composition using the Sanchez-Lacombe equation of state. Using the model, derived thermodn. properties, isothermal compressibility, isobaric expansivity, and internal pressure, were calculated This allowed for the estimation of the Hildebrand solubility parameters of these ionic liquids (ILs). Internal pressure was found to go through a maximum at low concentrations of ionic liquid in the case of [C₃C₁i.m.]Cl, [C₄C₁i.m.]Cl, and [C₆C₁i.m.]Cl. These observations were interpreted in terms of a significant effect of the alkyl chain length on the interactions between the IL and the cosolvent, EtOH. It is speculated that this is in part due to possible clustering between (Cl^–) and EtOH.
