Abstract
Objective Ethyl 4-nitrobenzoate was synthesized catalyzed by TiO_2/Fe~(3+). Methods Ethyl 4-nitrobenzoate was synthesized catalyzed by TiO_2/Fe~(3+) and tested by mass spectrum, the optimal conditions were confirmed by orthogonal tests. Results the optimal conditions were that the experiment yield is up to 88% when the temperature is 90℃, the reaction time is 2 hours, and the p-nitrobenzoic acid:EtOH is 1:6. Conclusion TiO2/Fe3+ can catalyze the esterification reaction effectively.
