DIFFUSION OF CARBON DIOXIDE INTO PRIMARY ALCOHOLS AND METHYL CELLULOSE ETHER SOLUTIONS

Abstract

Values of diffusion coefficients are reported for carbon dioxide and propane into ethanol, heptanol and octanol and for carbon dioxide into methyl cellulose ether solutions at 25°C. A comparison of the alcohol values with published data for mono-, di-, and tri-hydric alcohols and hydrocarbon mixtures is discussed in terms of the dependence of diffusivity on viscosity. An anomalous dependence is confirmed in the polymeric solutions examined.
