Group contribution and parachor analysis of experimental data on density and surface tension for members of the homologous series of 1-Cn-3-methylimidazolium chlorides was written by Souckova, Monika;Klomfar, Jaroslav;Patek, Jaroslav. And the article was included in Fluid Phase Equilibria in 2017.Application In Synthesis of 1-Methyl-3-propylimidazolium Chloride This article mentions the following:
The d. and surface tension values are presented that represent the best current knowledge of these properties for members of the homologous series of 1-Cn-3-methylimidazolium chlorides. To identify these values, a method was used based on the consistency requirement between selected background exptl. data and group contribution models of known best achievable accuracy. The models have been developed using our own and other authors data. For this purpose 64 and 119 new exptl. data on the d. and surface tension, resp., have been measured for [C1IM][Cl] and [CnMIM][Cl] with n = 2, 3, 4, 6, and 10 at temperatures from (263 to 365) K and at the pressure of 0.1 MPa. The d. was measured using the buoyancy method while the surface tension was measured by the Wilhelmy plate and du Nouy ring method in parallel. The resp. expanded combined uncertainties at the 0.95 confidence level of the resultant means of sets of individual measurements performed at a given temperature do not exceed 1 kg·m-3, 0.07 mN·m-1 and 1 mN·m-1. The estimated maximum deviations of the obtained recommended values from the true d. and surface tension values are 0.1 kg·m-3 and 0.15 mN·m-1, resp. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Application In Synthesis of 1-Methyl-3-propylimidazolium Chloride).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. 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.Application In Synthesis of 1-Methyl-3-propylimidazolium Chloride
