Title: CYANIDE CARBON ISOTOPE FRACTIONATION IN THE REACTION OF CYANIDE ION AND METHYL IODIDE. CARBON ISOTOPE EFFECT IN THE HYDROLYSIS OF METHYL IODIDE

Abstract

The C/sup 13/ isotope effects for isotopy at the cyanide carbon in the cyanization of methyl iodide and that in the hydrolysis of methyl iodide were investigated for water solvent at 11.4 to 58 deg . The results for hydrolysis are somewhat smaller than expected from the single value reported by Bender and Hoeg for the C/sup 14/ effect, bing at the 3.5% level; the cyanide carbon isotope effect in the cyanization is only about 1.0%. The results are examined in terms of a Bigeleisen-Wolfsberg-Slater three-particle model for the reacting system, special attention being paid to the choice between "atomic" and "molecular fragment" masses in the calculation of the temperature-independent factor in the isotopic rate-constant ratios. The data do not permit a clear choice to be made between these bases for the computations. (auth)
