Article Preview

The esterification reaction kinetics of ethylene glycol (EG) with phenyl phosphonic acid (PPOA) and benzene phosphinic acid (BPA) were studied in this article. Reactions were all carried out using benzene as a water carrying agent, and the reactant concentrations were determined by titration with NaOH. The reaction mechanisms were explained respectively. Various factors that may affect the extent of reaction were investigated such as reaction time and reaction temperature. The kinetic model of the apparent reaction was built. It was found that the apparent reactions both followed the pseudo-second order mode and the activation energy wre EPPOA 62.631 kJ/mol, EBPA 32.673 kJ/mol, respectively.
