Abstract : A method for the measurement of diffusion coefficients of vapors in gases is described in which the motion of a bead of volatile liquid is observed in a tube with a microporous membrane at one end. Results are given for air with ethyl acetate, benzene, ethanol, and methanol at 22.3C and 1 atm total pressure. The determined behavior of the diffusion-tube system may be considered in studies and measurements of diffusion coefficients of vapors. (Author)
