A new approach to sepiolite dispersion by treatment with ionic liquids was written by de Lima, Juliana A.;Camilo, Fernanda F.;Faez, Roselena;Cruz, Sandra A.. And the article was included in Applied Clay Science in 2017.Safety of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:
The possibility of sepiolite disaggregation is a challenge to enhance significantly its performance and extend its application. In this direction, this work introduces the treatment of sepiolite (Sep) with three different ionic liquid (IL). The used ionic liquids were 1-methyl-3-butylimidazolium bis(trifluoromethanesulfonyl) imide (BMImTf2N), 1-methyl-3-octylimidazolium bis(trifluoromethanesulfonyl) imide (OMImTf2N) and 1-methyl-3- dodecylimidazolium bis(trifluoromethanesulfonyl) imide (DMImTf2N). The influence on structural, thermal properties and morphol. in Sep treated with IL were evaluated using Fourier transform IR (FTIR) spectroscopy, X-ray diffraction (XRD), thermogravimetric anal. (TG), field emission SEM (FESEM), transmission electron microscopy (TEM), N2 sorption measurements, 29Si NMR (29Si NMR) and zeta potential. Sepiolite structure was preserved for all the samples treated with ionic liquids FTIR and XRD results show that BMImTf2N substitutes water mols. coordinated to Mg+2 more efficiently. Thermogravimetric anal. indicated that the interaction between Sep and IL delayed the release of water. From these data, it was also possible to confirm the presence of 5 mass% of IL in all samples. FESEM and TEM images demonstrated more disaggregated Sep fibers with IL, especially the samples treated with BMImTf2N. This fact is attributed to the immobilization of ionic liquid on Sep tunnels, which is coherent with 29Si NMR analyses. The potential applications of these modified sepiolites are as reinforcing agent for polymers, template for nanostructured materials and support for catalysts. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Safety of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).
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 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).Safety of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide
