Abstract

The kinetics of the esterification reaction of hydroxymethyl(phenyl)phosphinic acid (HMPPA) with Ethylene Glycol (EG) was studied. The reaction was carried out using benzene as a water carrying agent, and the reactant concentration was determined by titration of NaOH solution. The reaction mechanism was explained. Reaction time and reaction temperature were investigated to find their effect on the reaction. The kinetic model of the apparent reaction was built. It was found that the apparent reaction is a second order reaction, and the activation energy is 41.57 kJ/mol.
