摘要
The esterification reaction kinetics of gulonic acid with methanol catalyzed by cation exchange resin was investigated in a stirred batch reactor at different temperatures.After the influence of internal and external diffusion was eliminated,the positive and negative reaction rate constants were obtained by fitting the experimental data to a pseudo-homogeneous phase model.At the same time,the apparent kinetic modle of esterification was established.
