精确的热力学数据的测量在两个方面的重要性迅速增加：第一，这些数据是现代化学技术的基本要求；第二，它们有助于分子结构理论。近年来，对某些化合物基团的系统研究已经产生了它们的热力学性质的综合汇编；一个突出的例子是美国石油协会关于碳氢化合物的第44号研究项目。l然而，其他重要类别的化合物受到的关注要少得多，本文的目的是回顾仅含碳、氢和氧的有机化合物的热力学性质的现有知识状态。注意仅限于单个物质的热、熵、自由生成能、热容和相关性质的数据；二元和其他混合物的性质、热力学解离常数和临界数据被排除在外。在对实验和计算来源进行了简要的调查之后，详细考虑了对这些化合物的各种类别的可用测量值，并试图选择最可靠的值。然后讨论了数据中的规律，并将其与缺乏测量的热力学性质估计的最新方法联系起来。最后，综述了这些数据在确定键能项和自由旋转势垒高度方面的一些应用。
THE measurement of accurate thermodynamic data is of rapidly increasing importance from two aspects: first, the data are a basic requirement of modern chemical technology and secondly, they contribute to theories of molecular structure. In recent years systematic investigations of certain groups of compounds have resulted in comprehensive compilations of their thermodynamic properties; an outstanding example is the American Petroleum Institute Research Project 44 on hydr0carbons. l Other important classes of compounds have received much less attention, however, and the aim of this article is to review the existing state of knowledge of the thermodynamic properties of organic compounds containing only carbon, hydrogen, and oxygen. Attention is restricted to data on heats, entropies, and free energies of formation, heat capacities, and related properties of single substances; properties of binary and other mixtures, thermodynamic dissociation constants, and critical data are excluded. After a brief survey of experimental and computational sources, the available measurements on the various classes of these compounds are considered in detail and an attempt is made to select the most reliable values. Regularities in the data are then discussed and related to recent methods for the estimation of thermodynamic properties where measurements are lacking. Finally, some applications of the data to the determination of bond-energy terms and to barrier heights to free rotation are reviewed.
