Determination of thermal conductivity of organic liquids and liquid mixtures by thermal comparator method

Abstract

A Powell-type direct reading thermal comparator has been fabricated for the determination of thermal conductivity of organic liquids and liquid mixtures and has been calibrated against known thermal conductivities. Thermal conductivities of 28 pure organic liquids and of six binary mixtures of acetone with each of methanol, ethanol, n-butanol, n-pentanol, n-hexanol and n-heptanol have been determined, all at room temperature (26-28°C), and compared with the literature data. The agreement is satisfactory.
