And the article was included in Journal of Physical Chemistry B in 2013.Category: imidazoles-derivatives This article mentions the following:
Vaporization enthalpy of an ionic liquid (IL) is a key phys. property for applications of ILs as thermofluids and also is useful in developing liquid state theories and validating intermol. potential functions used in mol. modeling of these liquids Compilation of the data for a homologous series of 1-alkyl-3-methylimidazolium bis(trifluoromethane-sulfonyl)imide ([Cnmim][NTf2]) ILs has revealed an embarrassing disarray of literature results. New exptl. data, based on the concurring results from quartz crystal microbalance, thermogravimetric analyses, and mol. dynamics simulation have revealed a clear linear dependence of IL vaporization enthalpies on the chain length of the alkyl group on the cation. Ambiguity of the procedure for extrapolation of vaporization enthalpies to the reference temperature 298 K was found to be a major source of the discrepancies among previous data sets. Two simple methods for temperature adjustment of vaporization enthalpies have been suggested. Resulting vaporization enthalpies obey group additivity, although the values of the additivity parameters for ILs are different from those for mol. compounds In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Category: imidazoles-derivatives).
3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) 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 derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Category: imidazoles-derivatives
