TL;DR: In this article, the authors measured volume changes produced in Saran charcoal by the adsorption of water, methanol and benzene vapours, and found that the water uptake was about 75% of the saturation value.

TL;DR: In this article, a microscale test method was developed for testing catalysts, which was applied to treating pyrolysis vapours of Scots pine sawdust with ZnO, MgO, dolomite and limestone.

TL;DR: In this article, the Eucken factor for non-polar vapours showed systematic positive deviations from the theoretical values; strongly polar vapours show systematic negative deviations; weakly polar vapors show intermediate behaviour.
Abstract: The viscosities of the vapours of ethane, n-hexane, cyclohexane, benzene, methyl chloride, ethyl chloride, methyl alcohol, diethyl ether, acetaldehyde, acetone and acetonitrile have been measured at temperatures 35, 50, 65 and 78 degrees C and pressures between 1 and 3 cm. Measurements were made by observing the damping of a pendulum swinging in the vapour. A linear relation between coefficient of viscosity and temperature was found in all cases. The ratios of thermal conductivity to viscosity were calculated, using thermal conductivity values obtained recently in the same temperature range. The observed values of the Eucken factor for non-polar vapours show systematic positive deviations from the theoretical values; strongly polar vapours show systematic negative deviations; weakly polar vapours show intermediate behaviour. The theoretical implications of these phenomena are discussed.
