Elzawawy, E. Saad, I. Badr] Isotope exchange reaction between NaCl-36 and triphenyltin chloride in dioxane-water (80∶20% w/w) and ethanol-water (90∶10% w/w) mixed solvents has been studied at 25, 35 and 50 °C. The exchange reaction was found to proceed via a bimolecular SN2, limiting mechanism with reaction rates depending on the solvent used. Inhibition of the exchange in ethanol-water is probably due to solvation of chloride ion through hydrogen bond formation. The rate laws for the exchange reactions are: Re=3.24×109 e−65550/RT [Rh3SnCl] α [NaCl] in dioxanewater and Re=6.61×108 e−69600/RT [Ph3SnCl] α [NaCl] in ethanol-water, where α is the degree of dissociation of NaCl and Re is the rate of exchange in mol l−1 s−1. The activation parameters ΔH*, ΔS* and ΔG* are reported. Akaémiai Kiadó, 1992 Elzawawy F. Chemistry Department, Faculty of Science, Ain Shams University, Abbassia, Cairo, Egypt aut Saad E.
