| Abstract: | The esterification of p-hydroxy-benzoic acid and isoamyl alcohol by using dealuminated USY as catalyst was studied. The influence of SiO2/Al2O3 ratio in the catalyst, catalyst amount and reaction time were investigated. The experimental results show that under optimum conditions, the esterification could be finished in 6 hour with over 58% yield. At the same time, the esterification of salicylic acid and isoamyl alcohol was also studied. |
