Imidazolium Based Ionic Liquids: Impact of the Cation Symmetry and Alkyl Chain Length on the Enthalpy of Vaporization was written by Yermalayeu, Andrei V.;Zaitsau, Dzmitry H.;Loor, Manuel;Schaumann, Julian;Emel’yanenko, Vladimir N.;Schulz, Stephan;Verevkin, Sergey P.. And the article was included in Zeitschrift fuer Anorganische und Allgemeine Chemie in 2017.Synthetic Route of C11H20N2 This article mentions the following:
The vaporization thermodn. of sym. imidazolium based ionic liquids of the general formula [CnCnIm][Br] with the chains length n = 4, 5, 6, and 8 were investigated using a combination of DSC, TGA, and QCM methods with quantum chem. calculations Comparison of vaporization enthalpies for the sym. ([CnCnIm][Br]) and asym. imidazolium based ILs ([Cnmim][Br]) revealed a general trend with the lower vaporization enthalpies of the sym. species indicating a significant decrease of the Coulombic interactions affecting energetics of vaporization. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Synthetic Route of C11H20N2).
1-Octyl-1H-imidazole (cas: 21252-69-7) 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 based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Synthetic Route of C11H20N2
