Abstract: Temperature dependence of kinetic parameters of the alkaline hydrolysis of phthalic, isophthalic, and terephthalic acid monomethyl esters was studied by conductometric method. The relation was derived for the calculation of rate constant from the time dependence of the conductivity of the reaction mixture, which is valid for ionic reactants with equal initial concentrations. On the basis of temperature dependence of the activation enthalpy, the mechanism of the investigated reactions is discussed.
