| Abstract: | With acidic ionic liquid (CH2)3SO3Hmin]HSO4 as a catalyst, the mechanism of ethanol-related 4-Nitrobenzoic acid to form ethyl 4-nitrobenzoate is studied. Factors affecting the yields are investigated. Under optimized reaction conditions with molar ratio of: acid:ethanol:ionic liquid being 1:15:1.5, temperature being 85℃ and reaction time being 2 h, the yield is found to be able to reach 85.10%. Also found is that the ionic liquid remains catalytically active after 5 cycles of reuse. |
