CRITICAL CONSTANTS

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 1000 inorganic and organic sub-

stances. The properties and their units are:

T

b

: Normal boiling point in kelvins at a pressure of 101.325 kPa

(1 atmosphere); an “s” following the value indicates a subli-

mation point (temperature at which the solid is in equilib-

rium with the gas at a pressure of 101.325 kPa)

T

c

: Critical temperature in kelvins

P

c

: Critical pressure in megapascals

V

c

: Critical molar volume in cm

3

/mol

The number of digits given for T

b

, T

c

, and P

c

indicates the esti-

mated accuracy of these quantities; however, values of T

c

greater

than 750 K may be in error by 10 K or more. Although most V

c

values are given to three figures, they cannot be assumed accurate

to better than a few percent. All values are experimentally deter-

mined except for a few values, indicated by an asterisk*, that are

based on extrapolations. Methods of measurement are described

and critiqued in Reference 1.

Some of the compounds in the table undergo thermal decom-

position at temperatures near the critical temperature. The listed

values were obtained by pulse heating methods, as described in

the references by Nikitin, et al. (References 16, 31, 48, 50, etc.).

Many of the critical constants in this table are taken from re-

views produced by the IUPAC Commission on Thermodynamics

(References 1–9). Compounds are listed alphabetically by name,

with compounds not containing carbon preceding those that do

contain carbon.
