Application of the Scaled Particle Theory to the Calculation of Solvent Effects on the Menschutkin Reactions of Triethylamine with Ethyl Iodide,and Tripropylamine with Methyl Iodide

In this Paper, the structure of the transition state of the Menschutkin reaction was analyzed, and a method for determining the molecular parmeters of a transition state was pressented. On this basis, the scaled particle theory has been applied to the calculation of kinetic solvent effects on the reactions of triethylamine with ethyl iodide, and tripropylamine with methyl iodide. The results of calculation are in good agreement with those of experiment in protic, dipolar aprotic solvents, and in mixed solvents in the temperature range of 293.15 to 343.15K.
