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. 1739-84-0, formula is C5H8N2, Name is 1,2-Dimethyl-1H-imidazole. Their solubility in alcohol is lower than that in water and decreases with increasing molecular weight of the alcohols . Recommanded Product: 1,2-Dimethyl-1H-imidazole.
Li, Yuqing;Bi, Qiang;Cheng, Wen;Zhang, Zekun;Guo, Yinyin;Ren, Kang;Xue, Juanqin research published 《 Experimental study on the synergistic effect between novel imidazoline hexafluorophosphate ionic liquid with KI on mild steel in 1M H2SO4》, the research content is summarized as follows. In this paper, the corrosion inhibition performance of [C16DMIM] [PF6] ionic liquid on mild steel in 1M H2SO4 environment and the corrosion inhibition performance and mechanism of [C16DMIM] [PF6] compounded with KI, thiourea and formaldehyde, resp., were investigated based on serious corrosion hazards of metal pickling. The inhibition ability of [C16DMIM] [PF6] was evaluated by static weight loss method, electrochem. corrosion testing and microscopic morphol. anal., while the synergistic effect of the ionic liquid compounded with KI, thiourea and formaldehyde was explored by experiments and quantum chem. calculations(QC). The static weight loss results showed that the addition of 20 mg/L [C16DMIM] [PF6] could achieve 80.1% inhibition efficiency, and the combination of 20 mg/L KI could achieve 95.9% efficiency and maintain 94.1% efficiency after 7h. The electrochem. results showed that both [C16DMIM] [PF6] and the compounded corrosion inhibitor showed a mixed inhibition mode, and the impedance test revealed that the corrosion inhibitor formed a double elec. layer to reduce corrosion through the charge transfer process. SEM (SEM) observed that the surface of the mild steel was smooth and the corrosion depth was reduced after the effect of the compound corrosion inhibitor. The synergistic effect of ILs and KI is optimal. The synergistic mechanism is that I- preferentially adsorbs on the surface to form a bridge and thus attracts the protonated [C16DMIM] [PF6] for adsorption, which in turn enhances the strength of the adsorbed film and makes the protective film denser.
Recommanded Product: 1,2-Dimethyl-1H-imidazole, 1,2-Dimethylimidazole is used in the synthesis of 1,2-dimethyl-3-n-butylimidazoliumchloride and 1,2-dimethyl-3-n-propylimidazolium chloride. It also can be used in the synthesis of 1-(2-methoxyethyl)-2,3-dimethylimidazolium chloride and hexafluorophosphate salts.
1,2-Dimethylimidazole is a heterocyclic compound that contains nitrogen and carbon. It can be produced by the reaction between glyoxal and fatty acid in the presence of a base. 1,2-Dimethylimidazole has been shown to have biological properties such as an antioxidant effect. It is also used as a chemical intermediate for production of other chemicals such as 2-methylimidazole and 3-methylimidazole. 1,2-Dimethylimidazole has been shown to react with metal carbonyls to produce methylimines, which are useful intermediates in organic synthesis. The reaction mechanism involves hydrogen bonding and steric interactions between the imidazole ring and the metal carbonyl reactant., 1739-84-0.
