| Catalytic Synthesis of Isoamyl Salicylate by Heteropoly Acid |
| Guo Jun-sheng.（Department of chemistry.Xinxiang teacher's college; Xinxiang 453000; China） |
| Abstract：In the presence of Heteropoly acid catalys PW 12/SiO 2, isoamyl salicylate was synthesed from salicylic acid and isoamyl alcohol .The optimum conditions were as follow: molar ratio of salicyli acid to isoamyl alcohol was 1∶2.5, reaction time of reflux was 2h,mass of catalyst was 3% of salicylic acid.The yield of isoamyl salicylate was 96%.The catalyst was easy to be recovered,feasible to be used repeatedly,and less pollution to the environment. |
| Key words：heteropoly acid catalys; esterification; isoamyl salicylate |
