Abstract

The compendium of phase change enthalpies published in two parts in 2016 is updated to include new fusion, vaporization, and sublimation enthalpies published in the interim and includes some earlier data either previously missed or were unavailable. Also included in this article is an update of recent studies on the phase change enthalpies of polyaromatic hydrocarbons. Group values previously evaluated to adjust for temperature of phase changes are updated for aromatic compounds in view of recent experimental data. The new group parameters have been evaluated on the basis of their consistency in providing appropriate temperature adjustments to phase change enthalpies at T = 298 K as evaluated by a thermochemical cycle. This evaluation provides transition temperatures and about 1000 heats of fusion, 700 heats of vaporization, 500 heats of sublimation, and about 50 other heats of transitions for about 30 polyaromatic hydrocarbons and 1100 other molecules consisting of C1-C57 organic compunds, organometallics, inorganic compounds, and ionic liquids taken from about 900 references.

有机化合物的相变焓测量。2016年至2021年升华、蒸发和聚变焓的最新进展

2016年分两部分发布的相变焓简编进行了更新，包括在此期间发布的新的聚变、蒸发和升华焓，并包括一些以前遗漏或不可用的早期数据。本文还介绍了近年来对多环芳烃相变焓的研究进展。鉴于最近的实验数据，芳香族化合物的先前评估的用于调节相变温度的组值被更新。根据它们的一致性，对新的组参数进行了评估，这些参数通过热化学循环评估，在T=298K时为相变焓提供了适当的温度调节。该评估提供了约30种多环芳烃和1100种由C1-C57有机复合物、有机金属、无机化合物和离子液体组成的其它分子的转变温度和约1000个熔融热、700个蒸发热、500个升华热和约50个其它转变热，这些分子取自约900个参考文献。

期刊介绍： The Journal of Physical and Chemical Reference Data (JPCRD) is published by AIP Publishing for the U.S. Department of Commerce National Institute of Standards and Technology (NIST). The journal provides critically evaluated physical and chemical property data, fully documented as to the original sources and the criteria used for evaluation, preferably with uncertainty analysis. Critical reviews may also be included if they document a reference database, review the data situation in a field, review reference-quality measurement techniques, or review data evaluation methods.
