煤焦油热力学性质的研究进展

Progress in the Study of Thermodynamic Properties of the Coal Tar

简述了煤焦油组成及分析方法,综述了密度、分子量、临界性质、蒸汽压、气液相平衡、比热、熵、固液相平衡等物化数据及热力学性质的测量、估算及研究进展。指出建立煤焦油物性数据包,可为煤焦油研发和工程设计提供参考。

The coal tar composition and its analytical method were described in brief, and so were the measurement, estimation and research development of the thermodynamic properties such as density, molecular weight, critical proper- ties, vapor pressure, vapor-liquid phase equilibrium, specific heat, entropy, solid-liquid phase equilibrium, viscosity and surface tension. Attention was particularly focused on the analysis of the high molecular weight material. It pointed out that the establishment of the thermodynamic property data package could provide a reference for the research and development of the coal tar, as well as for relevant engineering design.
