Correlation of Isoprene-Maleic Anhydride Reaction Rate Constants in Mixed Solvents

抄録

Correlation of the Diels-Alder reaction rate constants of dilute solution for isoprene-maleic anhydride in the pure solvents such as hexane, ethyl acetate, toluene, monochlorobenzene and nitrobenzene, and the binary mixed solvents obtained by the authors are reviewed. For correlating the reaction rate constants in binary mixed solvents an empirical method based on the Arrhenius equation coupled with a Redlich-Kister type excess function introduced to obtain the excess activation energy in the mixed solvents is proposed. It is shown that the present model can correlate the reaction rate constants with a good agreement for the binary mixed solvents. Further, the applicability for the prediction of the excess activation energy for multicomponent mixed solvents by the addition of those for the constituent binary mixed solvents is presented.
