| Abstract: | Amyl salicylate was synthesized from salicylic acid and amyl alcohol with nano - scale rare earth complex super acid La3＋/SO4^2-/TiO2 as catalyst, and effect on the esterification was studied. Result showed that the esterification rate of salicylic acid was up to 95.2% when molar ratio of salicylic acid to amyl alcohol was 1 ： 2, usage of catalyst was 12%, toluene of 8 mL, and reaction at 130 - 140℃ for 2 h. |
