ENTHALPY OF VAPORIZATION
The molar enthalpy (heat) of vaporization ∆
vap
H, which is de-
fined as the enthalpy change in the conversion of one mole of liq-
uid to gas at constant temperature, is tabulated here for about 950
inorganic and organic compounds. Values are given, when avail-
able, both at the normal boiling point t
b
, referred to a pressure of
101.325 kPa (760 mmHg), and at 25°C.
The values in this table were measured either by calorimetric
techniques or by application of the Claperyon equation to the
variation of vapor pressure with temperature. See Reference 1 for
a discussion of the accuracy of different experimental techniques
and methods of estimating enthalpy of vaporization at other tem-
peratures. Several of the references present empirical techniques
for correlating enthalpy of vaporization with molecular structure.
Compounds are listed by systematic name, with compounds not
containing carbon preceding those that do contain carbon. To lo-
cate a compound by molecular formula or CAS Registry Number,
use the indexes to the table “Physical Constants of Organic
Compounds” in Section 3, which point to the entry in that table
from which the name can be determined.
