| Using N- methylimidazole bisulfate ionic liquid as a catalyst to synthesize ethyl benzoate. And Explore the factors which make great differences on the reaction yield, such as the molar ratio of reactants, reaction time, reaction temperature and different kinds of catalysts.We acquire the corresponding optimal conditions after experments:the ratio of ethanol to Benzoic acid is 5 to 1,solvent is cyclohexane, reaction for 4h at 70 ¡æand catalysted by the ionic liquid.Under this condition benzoate yields can arrive 82.50%.And the catalyst can be reused more than five times. The product can certificated by refractive index benzoate, FT-IR, UV. |
