Mol. structure of the conformers of 1-Cn-3-methylimidazolium chloride (n = 1 to 4) ionic liquids has been explored and the relationships with d. and viscosity have been studied using COSMO related methodologies. Effects of the number of conformers, ionic character, anion-cation relative positions and the alkyl chain length of the cation on predictions of properties have been analyzed. The quality of the predictions has been tested by comparing with exptl. results. Moreover, COSMO polarization charge densities, σ-profiles and σ-potentials of the conformers have been analyzed. Predictions on the chem. behavior based on the values of these properties in the conformers have been used to elucidate the affinity for electrophilic and nucleophilic reagents of ionic liquids In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Reference of 79917-89-8).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. Imidazole is a heterocyclic compound with a five-membered planar ring. It is amphoteric and highly polar. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Reference of 79917-89-8
