| Abstract: | Thermal conductivites at 30℃ and atmospheric pressure for 20 binary mixtures of 10 kinds of alcohols, methanol, ethanol, n -propanol, iso -propanol, n -butanol, iso -butanol, sec -butanol, tert -butanol, n -pentanol and iso -pentanol,with 1,2-dichloroethane and with cyclohexanone, respectively, were measured by transient hot wire method with the uncertainty of less than ±0.7%.Five different thermal conductivity predictive equations from literatures were used to calculate the thermal conductivities of these liquid mixtures investigated.The calculated values are compared with the experimental data from this work and the results were discussed. |
