Abstract

The parameters of the liquid-gas critical point are important constants in determining the behavior of fluids. This table lists the critical temperature, pressure, and molar volume, as well as the normal boiling point, for over 850 organic substances. The listed values are critically evaluated using NIST ThermoData Engine, TDE , designed to implement the dynamic data evaluation concept. The evaluated data have been generated only for compounds for which experimental data for critical properties are available. Group contribution methods such as Joback-Reed, Constantinou-Gani , Marrero-Pardillo , and Wilson-Jasperson as well as quantitative structure-property relationship (QSPR) methods were used within the TDE environment to validate available experimental data. Each recommended value in the table is characterized with a combined expanded uncertainty (level of confidence, approximately 95 %) listed in parentheses. The majority of the values of the normal boiling temperatures provided in the table are taken from the compilation presented in the 90th Edition of the CRC Handbook of Chemistry and Physics. Some additional values of the normal boiling temperature, along with the combined expanded uncertainties associated with them in parentheses, are generated with the use of TDE. Only references to original experimental data actually used by TDE to generate critically evaluated data are indicated for each compound.
