Study on properties of N,N’-dialkyl imidazole ionic liquid surfactant was written by Wang, Li-yan;Sun, Zhu;Yu, Ting-ting;Zhao, Bing;Li, Kuo. And the article was included in Yinran Zhuji in 2013.Electric Literature of C11H20N2 This article mentions the following:
Intermediates N-octyl imidazole was synthesized from imidazole and bromooctane. N,N’-dialkyl imidazole ionic liquid surfactants were synthesized from bromoalkanes (bromooctane, bromodecane, bromo-dodecane, bromotetradecane and bromohexadecane) and N-octyl imidazole under the assistance of ultrasound. The intermediate and target product were characterized by 1H-NMR. The sterilization, surface tension, foaming properties and emulsifying properties of N,N’-dialkyl imidazole ionic liquid surfactants were determined The results showed that N,N’-dialkyl imidazole ionic liquid surfactants can inhibit the growth of Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Penicillium when the concentration of products were above 500 mg/L, and the greater the concentration, the better the anti-bactericidal performance. N,N’-dialkyl imidazole ionic liquid surfactants can reduce the surface tension of aqueous solution which reduced with the concentration increasing. With alkyl chain increasing, the foaming property and foam stability of N,N’-dialkyl imidazole ionic liquid surfactants increased first and then decreased. Using benzene as the oil phase, with alkyl chain increasing, the emulsifying ability of N,N’-dialkyl imidazole ionic liquid surfactants increased first and then decreased. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Electric Literature of C11H20N2).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. 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).Electric Literature of C11H20N2
