Abstract:The reaction of methol and salicylic acid with solid superacid ZrO 2/SO 2- 4 as catalyst was studied. Continuously dropped methol under boiling condition, and controlled the speed of dropping and distilling to be same for 6h. The conversion of salicylic acid reaches to 81.6%. |
Key words:methyl salicylate; solid super acid; esterification |
