| Abstract: | The kinetics of the thermal meso/dl isomerization of meso-diethyl 2, 3-dicyano-2, 3-diphenylsuccinate were determined in ethylbenzene, ethylphenyl ether, chlorobenzene, methyl benzoate, phenyl cyanide and 1, 2-dibromoethane at 90, 100, 110 and 120℃ respectively, The equilibrium constants, rate constants and activation parameters of the thermal meso/al isomerization was obtained. The results indicated that the equilibrium constants are not sensitive to both solvents and reaction temperature. |
