用相对水平平行板法（稳态法）测定了常压下10种纯液体醇及其4种二元混合物的导热系数。纯醇的导热系数测定温度为20 ~ 70°C，二元混合物的导热系数测定温度为25.0和50.0°C。以前的相关模型开发的基础上的晶格模型与空穴理论的概念耦合的非极性液体的热导率已成功地扩展到极性液体，如醇通过引入一个新的经验参数来表示极性效应。计算导热系数时所需的势参数和经验参数的折合值可由Pitzer偏心因子和Stiel极因子的二次函数关联。本模型还扩展到酒精混合物通过使用二元相互作用参数。
The thermal conductivities of ten pure liquid alcohols and four of their binary mixtures were measured by use of the relative horizontal parallel-plate method (steady-state type) under atmospheric pressures Measurements for pure alcohols were carried out at temperatures from 20 to 70°C and for binary mixtures at 25.0 and 50.0°C. A previous correlation model developed for the thermal conductivities of nonpolar liquids on the basis of the lattice model coupled with the hole theory concept has been successfully extended to polar liquids such as alcohols by the introduction of a new empirical parameter to represent the polar effect. Reduced values of the potential parameters and the empirical parameter, needed in the calculation of thermal conductivities, could be correlated by quadratic functions of Pitzer''s acentric factor and Stiel''s polar factor. The present model is also extended to alcohol mixtures by use of binary interaction parameters.
