| Abstract: | The solid superacid SO 2- _4/TiO_2/La 3+ was used as the catalyst in the isamyl isvalerate reaction The experimental results showed that the best esterification conditions are: the reaction temperature was 130 ℃, the reaction was time 3 h, isamyl to isvaleric acid was 1 5∶1 0 (mol), and w (catalyzer) = 0 9% of the total initial materials Conversion of isvaleric acid amounts to 98% The catalyst could be separated from reaction materials easily, and could be reused. |
