ESTERIFICATION OF SALICYLIC ACID USING Ce4+ MODIFIED CATION-EXCHANGE RESIN AS CATALYST

The esterification of salicylic acid with methanol was carried out over a series of Ce4+modified cation-exchange resins. The effect of different reaction conditions was studied on the conversion of salicylic acid, and the optimal reaction parameters were obtained. The experimental results indicated...
