Accurate Measurements of the Thermal Conductivity of n-Docosane, n-Tetracosane, 1,6-Hexanediol, and 1,8-Octanediol in the Solid and Liquid Phases

Abstract New measurements of the thermal conductivity n -docosane, -tetracosane, 1,6-hexanediol, and 1,8-octanediol, in solid liquid phase, are presented. The technique employed is transient hot-wire technique, based on a full theoretical model. absolute characterized by an uncertainty 1%. At 95% confidence level, standard deviations 0.40% for phase (267 K to 308 K), 0.60% (330 360 K); (265 306 0.30% (339 363 0.70% (263 296 (327 351 1,8-octanediol 1.1% 312 0.50% (344 356 respectively.
