| Abstract: | Solid superacid TiO_2/ SO~(2-)_4 was used in the synthesis of isoamyl salicylate.The effects of molar ratios of isoamyl alcohol to salicylic acid,the amount of catalysts,reaction time and reaction temperature on the yields of isoamyl salicylate were studied.The results showed that under the optimal conditions: molar ratio of acid to alcohol 1∶4,1.6 g catalyst,reaction time 5 h,the yield was 94.6%.The catalysts were characterized with XRD,nitrogen adsorption,etc. |
