| Abstract: | In the title reaction at different temperatures (30-45°C) the rates have been measured as a function of free [phenol]. A linear relationship is found between the observed second order rate coefficient and the ratio [CH3OH]/[PhOH]. This has been attributed to concurrent and consecutive methanolysis by methoxide ions arising from the possible proton exchange between methanol and phenoxide ion. The thermodynamic parameters of activation of the reaction of I-chloro-2,4-dinitrobenzene with aryl oxides and methoxide anions have been calculated. From the kinetic results it is possible to calculate the equilibrium constant of the reaction: CH3H+ArO-  CH3O-+ArOH |
