一、前言纯物质的临界温度值在科技理论与工程领域中都是最重要的物理性质之一。可是,目前大多数物质的临界温度值还必须由它们本身的某些特性推算而得。这或由于数值测定中技术上有困难,或由于多原子物质在其临界温度时的热不稳定性,或由于物质精制成纯品的困难,所以对未知临界温度值的推算是具有重要意义与生命力的。本文在研究了250种以上的有机物的正沸点与临界温度的关系后,按其类别提出27个推算临界温度值的新的简单的关联
I. INTRODUCTION The critical temperature of pure matter is one of the most important physical properties in the fields of scientific theory and engineering. However, most of the current material critical temperature values must also be derived from some of their own properties. This may be of great importance to the estimation of the unknown critical temperature either because of technical difficulties in the numerical determination, because of the thermal instability of the polyatomic material at its critical temperature, or because of the difficulty of refining the material into the pure product With vitality In this paper, after studying the relationship between the positive boiling point and the critical temperature of more than 250 kinds of organic compounds, 27 new simple correlations for estimating the critical temperature value are proposed according to their categories
