The dependence of the rate constant of alkaline hydrolysis of diphenic acid monomethyl ester and terephthalic acid monomethyl ester on ionic strength and temperature was studied together with the specific influence of some electrolytes on the reaction rate. Thermodynamic activation parameters extrapolated to zero ionic strength and critical interionic distances of reacting ions were calculated from the temperature dependences of the rate constants.
