摘要
实验用0.5 mol的C_6H_(13)Br和0.5 mo L的C_4H_6N_2合成[HEPMIM]Br离子液体,得到棕黄色油状粘稠液体为[HEPMIM]Br,用IR和UV表征了[HEPMIM]Br。[HEPMIM]Br在CH_3CN中发生了红移,实验结果为λmax(H_2O)<λmax(C_2H_5OH)<λmax(CH_3CN),溶剂的极性和p H值影响[HEPMIM]Br的UV光谱。
A new type of brown ionic liquid 1-heptyl-3-methyl imidazole bromide was synthesized. Its structure was characterized by IR and UV. The results show that the wavelength from big to small is acetonitrile, alcohol and water; the polarity and p H of the solvent can affect the UV spectrum.
