The viscosity of liquids (a) Normal octanol at atmospheric pressure (b) An equipment for high pressures

University of British Columbia

Theories of Liquid Viscosity lead to equations giving the variation of the viscosity with temperature and pressure, but give poor agreement with experimental values, particularly for associated compounds such as normal alcohols. The lack of accurate measurements under pressure for these compounds is being particularly felt in the development of such theories. Apparatus has been assembled and calibrated for carrying out measurements on the normal alcohols over a range of pressures to 10,000 psi and temperatures to 100°C. Parallel with the development of this pressure viscometer, the viscosity of n-octanol at atmospheric pressure has been determined in standard capillary viscometers for a range of 15° to 90°C. The data have been examined and correlated on the basis of standard viscosity-temperature equations with emphasis on their relevance in an important homologous series. The results have laid the groundwork for measurement under pressure.
