Abstract

The solid superacid SO 2- 4/ TiO 2 Al 2O 3 was used in catalytic synthesis of isoamyl salicylate (IAS). The suitable conditions of preparation of the catalyst and synthesis of IAS were obtained: molar ratio of titanium sulfate to aluminum sulfate=1∶4, calcinations temperature=500 600?℃,weigh of the catalyst= 1.5?g , reaction temperation=195 200?℃ , reaction time=5 6?h. The relation between activity and structure of SO 2- 4/ TiO 2 Al 2O 3 catalyst was studied by IR 、XRD technique.
