Studies of thermal conductivity of liquids. Part I

Abstract Values of thermal conductivity and temperature coefficients for fifty‐three pure organic liquids, obtained with newly designed, extensively tested apparatus, are presented. For thirty‐one of these liquids values of thermal conductivity or temperature coefficients have not been previously reported. The statisically determined maximum error in the presented values of thermal conductivity of liquids is ±1.50%. A method of correlating the thermal conductivity of liquids based on a modified statement of the theory of corresponding states is presented. Group contributions to the thermal conductivity were calculated. The thermal conductivity of liquids was predicted by this method and the average deviation of the calculated from the observed values for forty‐seven liquids is ±1.50%. The proposed method of correlation permits the calculation of the thermal conductivity of a series of liquids at any temperature from a single known value.
