摘要：

A simple method for measuring diffusion coefficients of gases in liquids using capillary cells has been shown to give accurate results for the diffusivities of carbon dioxide in water, methane in carbon tetrachloride, and carbon dioxide in ethanol when compared with reported values. Diffusivities were also measured at 30°C. for ethane in n‐hexane and ethane in n‐heptane, and at 40°C. for ethane in n‐heptane. The steady‐state capillary cell technique appears to be capable of giving reliable diffusivities for a large number of gas‐liquid systems. Copyright © 1968 Canadian Society for Chemical Engineering
