Low-melting, low-viscous, hydrophobic ionic liquids: 1-alkyl(alkyl ether)-3-methylimidazolium perfluoroalkyltrifluoroborate was written by Zhou, Zhi-Bin;Matsumoto, Hajime;Tatsumi, Kuniaki. And the article was included in Chemistry – A European Journal in 2004.Reference of 79917-89-8 This article mentions the following:
Twenty two hydrophobic ionic liquids, 1-alkyl(alkyl ether)-3-methylimidazolium ([Cmmim]+ or [CmOnmim]+; where Cm is 1-alkyl, Cm = nCmH2m+1, m = 1-4 and 6; CmOn is 1-alkyl ether, C2O1 = CH3OCH2, C3O1 = CH3OCH2CH2, and C5O2 = CH3(OCH2CH2)2) perfluoroalkyltrifluoroborate ([RFBF3]–, RF = CF3, C2F5, nC3F7, nC4F9), were prepared and characterized. Some of the important physicochem. properties of these salts including m.p., glass transition, viscosity, d., ionic conductivity, thermal and electrochem. stability, were determined and were compared with those of the reported [BF4]–-based ones. The influence of the structure variation in the imidazolium cation and the perfluoroalkyltrifluoroborate ([RFBF3]–) anion on the above physicochem. properties is discussed. The key features of these new salts are their low m.ps. (-42 to 35°) or extremely low glass transition (between -87 and -117°) without melting, and considerably low viscosities (26-77 cP at 25°). In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8Reference of 79917-89-8).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) 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 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).Reference of 79917-89-8
