Abstract

Ethyl p Hydroxyl Benzoate was synthesized with Toluene p Sulfonic Acid as catalyst. Actors in fluencing yield were discussed. The optimum reaction conditions are alcohol/acid mole ratio 4∶1,catalyst amount 7.5%, reaction time 3.5 hour. The yield under the optimum conditions was up to 75%.
