“…Comparison between Reported and Present Values of Thermal Conductivity. A comparison between the previously reported data in the literature − and the present results is shown chronologically in Table except for the cases of some materials for which the thermal conductivity was not found. These were not intentionally selected, and their uncertainty is mostly unclear.…”

Experimental values of the thermal conductivity λ and thermal diffusivity a of 29 pure substances are presented in the temperature range of -15 °C to 65 °C under atmospheric or saturation pressure. The materials measured were as follows: alkenes (1-pentene, 1-hexene, 1-heptene, 1-octene, 2,3-dimethyl-1-butene, 2,3-dimethyl-2-butene), cycloalkenes (cyclopentene, cyclohexene), cycloalkanes (cyclopentane, cyclohexane, methylcyclopentane, cycloheptane, cyclooctane), aromatics and their relatives (benzene, ethylbenzene, o-, m-, and p-xylenes, propylbenzene, isopropylbenzene, hemimellitene, pseudocumene, mesitylene, 1,3-cyclohexadiene, 1,4-cyclohexadiene, bicyclo[2.2.1]hepta-2,5-diene [norbornadiene]), and deuterated hydrocarbons (benzene-d 6 , cyclohexane-d 12 , toluene-d 8 ). Measurements were made with the transient hot-wire method in the manner previously presented, and the thermal diffusivity values were corrected by reference to the heat capacity of heptane as a reference material. Heat capacities (volumic, c p F; massic, c p ; molar, C m,p ) were complementally derived from the relationship c p F ) λ/a, with values for the density and the molar mass. The uncertainty of the data is estimated to be 0.4% for the thermal conductivity (absolutely measured) and about 1.8% for the thermal diffusivity (with a coverage factor of k p ) 2; p ) 95%), although that of λ (not of a) is possibly inferior for a few substances containing slightly more impurities (i.e., mainly other isomers).
