Abstract：
:Diffusive isotope fractionation of non- and perdeuterated benzenes and toluenes in aqueous solution was investigated. The experimental method was based on a Stokes diaphragm cell. The isotope composition of diffusate and retentate was found to be identical within a range of uncertainty of ±5‰ for benzene and ±10‰ for toluene. These data are consistent with a previous fractionation study using phase-transition kinetics as the potentially fractionating step. The present study contributes to strengthening the data base for diffusive isotope fractionation of organic compounds in aqueous solution. According to the presented data, diffusion of naturally occurring, monodeuterated organic compounds does not significantly affect their hydrogen isotope pattern.
