The kinetic study of the solvent effect of alkali catalysed hydrolysis of dimethyl phthalate was studied in water-t-butanol media having varying concentration of t-butanol (from 20 to 80% v/v). The rate of the raction was found depleting with gradual addition of the organic content (t-butanol) of the reaction were found to be enhanced simultaneously with the addition of more and more t-butanol in the reaction media. From the simultaneous enhancement in three thermodynamic parameters, it has been inferred that the sold reaction is enthalpy dominating and entropy controlled. From the plots of rH* against rS*, the iso-kinetic temperature of the reaction has been evaluated from the slope of the plot. The numerical value of its kinetic iso-kinetic temperature, which is greater than 300, it thas been inferred that there is strong solvent-solute interaction in the reaction media in presence of t-butanol in it.
