“…• ONDA, el ol_ (24) é GERTZ AND LOESCHKE One might have expected the diffusivities to decrease with increasing molecular weight (16), but the diffusivities of C4H8 are actually higher than those of C2H4 and C3H6 at any one temperature. The experimental findings do not seem to indicate an apparent correlation between the chemical structure and the diffusivities for these three gases.…”

“…The series in the exact solution converged very slowly when the Gz value was large, requiring 2500 terms when Gz = 106. If K is defined as the correction factor by which the diffusivity, as computed by Equation 7, should be multiplied to give the exact value of the diffusion coefficient, D, the following values show that the correction is small; however, the correction was applied in this work: The apparatus used in carrying out the measurements was similar to that used by Onda, Okamoto, and Yamaji (24). The major parts of the apparatus were: a constant head water reservoir, a thermostatic bath, and an absorption chamber.…”

Absorption of gas by a liquid jet was used to measure the diffusivities of carbon dioxide, ethylene, propene, and butene-1 in pure water at various temperatures and at atmospheric pressure. Diffusivities for the latter three gases are reported for the first time. As a first step, the cofflcients of diffusion of carbon dioxide in pure water at various temperatures were determined and compared with values reported by previous investigators and with values predicted theoretically. The agreement between the CO2 diffusivities measured in this study, and other studies and the theoretical predictions, was quite satisfactory. Then the coefficients of diffusion were determined for C2H4, C Hc,, and C4H8 (butene-1) in pure water at temperatures from 6°to 65°C. The agreement between the experimental and theoretically predicted diffusivities was good for CO2 but not for the other gases.DlFFUSIVITY IS ONE of the controlling factors in interphase mass transfer in gas-liquid systems. Measurement of diffusivities is also of interest in developing and evaluating models of the liquid state. This study presents new data for the diffusion coefficients of C2H4, C3H6, and C4H8 (butene-1) in water from 6.5°to 65°C ., and also compares the diffusion coefficients of C02 obtained in an identical way with the values reported by other investigators.Reliable and accurate values of diffusivity for gas-liquid systems are not easy to obtain because of numerous experimental problems. Weissberger (42) Crank ( 6), Johnson and Babb (17), and Jost (18) among others discuss the use of diaphragm cells, capillary tubes, refractive index, radioactivity, etc. to make the measurements required to

“…The absorption of gas into a liquid jet, such as shown in Fig. 2, is widely used to determine diffusion coefficients for a number of reasons (15,22,29,50,52,76,85,91,94,102,121,136,144,145). Jets are simple in design, have freedom from ripples, have small end effects, are stable, and have such short contact time that surface active agents do not have time to adsorb on the surface.…”

“…For (CO 2 + water), abundant data for the diffusion coefficient at infinite dilution are available [7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34]. Fewer data are available for CO 2 in ethanol [35,10,11,36,37,29,38], cyclohexane [39], toluene [10,40,41], methanol [35,10,11,19,31,42], and acetone [10]. For CH 4 , diffusion coefficients have been investigated before in water [8,43,9,44,…”

Diffusion coefficients at infinite dilution are important basic data for all processes involving mass transfer. They can be obtained from studying samples in equilibrium using nuclear magnetic resonance spectroscopy with pulsed field gradients (PFG-NMR), a technique which is widely used in chemistry but is only rarely applied in engineering studies. This advantageous technique was employed here to measure the self-diffusion coefficients of diluted solutions of carbon dioxide and methane in the pure solvents water, ethanol, cyclohexane, toluene, methanol, and acetone at 298.15 K. For the systems (carbon dioxide + water) and (carbon dioxide + ethanol), measurements were also carried out at 308.15 K, 318.15 K and 333.15 K. Except for (methane + water) and (methane + toluene), no literature data for the methane-containing systems were previously available. At the studied solute concentrations, there is practically no difference between the self-diffusion coefficient and the mutual diffusion coefficient. The experimental results are compared to experimental literature data as well as to results from semi-empirical methods for the prediction of diffusion coefficients at infinite dilution. Furthermore, molecular dynamics simulations were carried out for all systems to determine the diffusion coefficient at infinite dilution based on
