Relationship between mesoscale dynamics and shear relaxation of ionic liquids with long alkyl chain was written by Yamaguchi, Tsuyoshi;Mikawa, Ken-ichi;Koda, Shinobu;Fujii, Kenta;Endo, Hitoshi;Shibayama, Mitsuhoro;Hamano, Hiroshi;Umebayashi, Yasuhiro. And the article was included in Journal of Chemical Physics in 2012.SDS of cas: 404001-48-5 This article mentions the following:
The shear relaxation spectra of three imidazolium-based ionic liquids, 1-methyl-3-octylimidazolium chloride (C8mimCl), 1-methyl-3-octylimidazolium hexafluorophosphate (C8mimPF6), and 1-dodecyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide (C12mimTFSA) were measured and compared with the intermediate scattering functions determined with neutron spin echo (NSE) spectroscopy. The shear relaxation is slower than that predicted from the relaxation of the main peak of the structure factor that is common to other mol. liquids, whereas it is faster than that from the relaxation of the pre-peak, that corresponds to the correlation length of about 10 nm specific to ionic liquids with an intermediately long alkyl chain. The role of the pre-peak structure in the mechanism of shear viscosity of ionic liquids is discussed based on the comparison between NSE and shear relaxations. (c) 2012 American Institute of Physics. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5SDS of cas: 404001-48-5).
3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. Imidazole has been usedin the lysis, wash and elution buffer for the purification of histidine tagged Sonic Hedgehog(shh-N) protein, in elution buffer in stepwise gradient for the purification of histidine tagged aldo keto reductases using nickel affinity chromatography, as a component of homogenization buffer for the purification of phagosomal compartments from dendritic cells.SDS of cas: 404001-48-5
