3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. 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.Name: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide

Cation Symmetry effect on the Volatility of Ionic Liquids was written by Rocha, Marisa A. A.;Coutinho, Joao A. P.;Santos, Luis M. N. B. F.. And the article was included in Journal of Physical Chemistry B in 2012.Name: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

This work reports the first data for the vapor pressures at several temperatures of the ionic liquids, [CN/2CN/2i.m.][NTf2] (N = 4, 6, 8, 10, 12) measured using a Knudsen effusion apparatus combined with a quartz crystal microbalance. The morphol. and the thermodn. parameters of vaporization derived from the vapor pressures, are compared with those for the 1-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide series, [CN-1C1i.m.][NTf2] (N = 3 – 9, 11, and 13). It was found that the volatility of [CN/2CN/2i.m.][NTf2] series is significantly higher than the asym. cation ILs with the same total number of carbons in the alkyl side chains, [CN-1C1i.m.][NTf2]. The observed higher volatility is related with the lower enthalpy of vaporization. The sym. cation, [CN/2CN/2i.m.][NTf2], presents lower entropies of vaporization compared with the asym. [CN-1C1i.m.][NTf2], indicating an increase of the absolute liquid entropy in the sym. cation ILs, being a reflection of a change of the ion dynamics in the IL liquid phase. Moreover both the enthalpy and entropy of vaporization of the [CN/2CN/2i.m.][NTf2] ILs, present a clear odd-even effect with higher enthalpies/entropies of vaporization for the odd number of carbons in each alkyl chain ([C3C3i.m.][NTf2] and [C5C5i.m.][NTf2]). In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Name: 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).
