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. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Quality Control of 1-Methyl-3-propylimidazolium Chloride).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Quality Control of 1-Methyl-3-propylimidazolium Chloride
