| Abstract: | With esterification of benzonic acid and butanol as model reaction, we had got the rate constant k. the activation energy Ea, the activation entropy DrSm,the activation enthalpy DrHm of esterification catalyzed by solid superacids. Depending on the result, we supposed that the esterification was catalyzed by lewis acid centers in the solid superacids. |
