Abstract
Sorption kinetics and diffusion of liquids and binary liquid mixtures of bis(2-methoxyethyl) ether with methyl acetate, ethyl acetate, butyl acetate, diethyl succinate, methyl benzoate, ethyl benzoate, and meth yl salicylate into tetrafluoroethylene + propylene copolymer membranes have been studied at 298.15 K using a sorption gravimetric method. Co efficients of diffusion have been calculated from Fick's equation. The dependence of sorption and diffusion coefficients on viscosity, molar volume, excess molar volume, and Flory-Huggins interaction parameter has been discussed.
