以β-氯乙基苯醚、苄氯、N-甲基咪唑、浓硫酸等为原料,通过多步反应合成了在N -甲基咪唑阳离子上分别含烷氧基苯磺酸和烷基苯磺酸侧链结构的两种水溶性、室温下呈液相的新型Brφnsted酸性离子液体,总产率分别为79.8%和83.6%.选配的阴离子为[HSO_4]~-,进一步增加了离子液体的酸性.产物结构通过红外光谱、核磁共振氢谱得以确认. |

Two novel water and air stable Bronsted-acidic ionic liquids were synthesized.One had an alkoxy benzene sulfonic acid group in the N-methylimidazolium cation,and the other possessed an alkyl benzene sulfonic acid group in the N-methylimidazolium cation.The counteranions were [HSO_4]-for both compounds.The total yield was 79.8% and 83.6%,respectively. All the compounds were new,and their structure was confirmed by IR spectrometry and ~1HNMR. |
