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.

摘要： 采用瞬态热丝法液体热导率测量装置测定 10种醇 (甲醇、乙醇、正丙醇、异丙醇、正丁醇、异丁醇、仲丁醇、叔丁醇、正戊醇和异戊醇 )分别与 1,2 -二氯乙烷、环己酮组成的 2 0个二元体系在常压、 30℃和不同组成时的热导率 ,测量误差± 0 .7% .用文献中 5种热导率方程对所测液体的热导率做了推算 ,将计算值与实测结果做了比较 ,并进行了讨论
