摘要
This review is an introductory survey of the vapor-liquid critical properties of pure substances. It will be followed by a series-of reviews on the critical properties of elements and compounds, each dealing with a well-defined group of substances in detail. The historical background of the vapor-liquid critical point is outlined, and this is followed by a discussion of the nature of the critical point and of the experimental methods used to determine critical temperatures, pressures, and volumes. The effect of impurities, including mercury, on the apparent critical properties is examined. Many substances decompose at or near their critical point; methods designed to minimize this problem or procedures to allow for decomposition are presented. Finally, a classification of methods, to be used in subsequent parts of this project, is given, and the accuracy and reproducibility of the results are discussed.
