Viscosities of Some Lower Aliphatic Alcohols at Constant Volume

From an analysis of all the published experimental data for methyl, ethyl, n-propyl, isobutyl, and n-octadecyl alcohols, it is shown that, even for these compounds, at constant volume logη is a rectilinear function of 1/T and the general pattern of behavior is similar to that described previously. Ev, the energy of activation of viscous flow at constant volume, is plotted as a function of volume, and the curve for ethyl alcohol shows an apparently anomalous minimum.
