A compendium of phase change enthalpies published within the period 1880–2010 is
reported. Phase change enthalpies including fusion, vaporization, and sublimation are
included for organic, organometallic, and a few inorganic compounds. This compendium
is a combination of three previous series focusing on phase change enthalpies updated to
2009. Sufficient data are presently available for some compounds to permit thermodynamic cycles to be constructed, an important manner of evaluating the reliability of the
measurements. Temperature adjustments of phase change enthalpies from the temperature
of measurement to the standard reference temperature, T = 298.15 K, are briefly disscussed and a protocol for doing so is illustrated. © 2010 American Institute of Physics.

1. Introduction
Transition enthalpy measurements, that include measurements of sublimation, vaporization, and fusion of organic
compounds, have been reported for well over 100 years.
These properties find use in a number of disciplines that
include chemical and enviromental engineering, physics, and
chemistry. The magnitude of these properties, when viewed

in perspective, provides valuable incite into the nature of
both intra- and intermolecular interactions and thus are of
interest to both experimentalists and theoreticians. While
generally weaker than the chemical bond, the interactions
responsible for these enthalpies are similar to those responsible for the self-assembly that occurs in everything from
liquid crystals to biological systems.
The sheer number of measurements reported in the literature is testimony to the importance of these properties in
providing an understanding of our physical world. One goal
of this compendium is to bring together in one location measurements that often are scattered in the literature, sometimes
in obscure places. Additionally, some of these measurements
have significant errors associated with the property reported.
These uncertainties are often not easily discernable, even to
those familiar with the field. Despite significant improvement in instrumentation over the years, even recent measurements have errors significantly larger than reported. Provided
all necessary transition enthalpies are available, an evaluation of the thermodynamic consistancy of the values reported
is possible. This compendium is an effort to compile these
phase change enthalpies in a manner such that an assessment
can be made as quantitatively as the data permits.
Equation 共1兲 is the thermodynamic equality that relates
phase change enthalpies, fusion, vaporization, and sublimation enthalpies but only if all enthalpies are referenced to a
common temperature. Since experimental fusion enthalpies
measured at ambient pressures are confined to the temperature Tfus, this equality is only applicable at the fusion temperature unless each enthalpy can be adjusted for temperature. Since T = 298.15 K is the usual temperature of
reference, adjustment of each of these enthalpies to T
= 298.15 K is preferable. A number of methods, some experimental and others computational, have been used to adjust
both vaporization and sublimation enthalpies to T
= 298.15 K. A number of these have been summerized in
previous
compilations
关1987CHI,
2003CHI/ACR2,
1999CHI/NIC兴. The relationships outlined in this compendium for adjusting sublimation and vaporization enthalpies,
those most familiar to the authors, have been in use for some
time and have given acceptable results. Fusion enthalpies
have been adjusted by combining the relationships used to
adjust vaporization and sublimation enthalpies. The protocol
is described below,
⌬subHm共T兲 = ⌬vapHm共T兲 + ⌬fusHm共T兲.

2. Phase Change Enthalpies
As noted above, phase change enthalpies are temperature
dependent. Therefore, to adjust a phase change enthalpy for
temperature requires the heat capacity of the two phases in
question. For sublimation enthalpies, while the heat capacity
of the solid, C p,m 共s, 298.15 K兲, may be available, the heat
capacity of the corresponding gas phase value, C p,m 共g,
298.15 K兲, is generally not. Similarly for vaporization enthalpies, the experimental heat capacity of the liquid at T

= 298.15 K, C p,m 共l, 298.15 K兲, may be available, experimental data for the corresponding gas phase are usually lacking. For fusion enthalpies requiring both C p,m 共s, 298.15 K兲
and C p,m 共l, 298.15 K兲 for this adjustment, only one of these
two properties is generally available at T = 298.15 K. As a
means of circumventing the lack of sufficient experimental
data, empirical and theoretical relationships have been developed to adjust solid and liquid phase change enthalpies with
temperature. Many of the phase change enthalpies reported
this compilation have been adjusted to T = 298.15 K by the
authors. The reader should consult the original literature to
determine how this adjustment was made. In cases where the
phase change enthalpy is reported only at the mean temperature of measurement, a few empirical relationships that can
be used to adjust each respective phase change are discussed
briefly below.
2.1. Estimation of heat capacities
A number of methods have been developed for the estimation of heat capacities 关1990LYM/REE, 1908KOL/KUK,
1993CHI/HES兴. The method employed in this article is a
method developed by the authors and shown to give reasonably good temperature adjustments when used in combination with the equations to be described below 关1998CHI,
1999SAB/XU, 2008ROU/TEM兴. The method is based on
group contributions. The group values 共⌫兲 used in the estimation of C p,m共l , 298.15 K兲 and C p,m共s , 298.15 K兲 are provided in Table 1. For reference, Figs. 1 and 2 provide an
example of a hypothetical molecule containing all of these
groups. Each group, identified numerically in column 2 of
Table 1, can be located in these figures. Some estimations
using examples taken from the recent literature are given in
Table 2. Note that some of the group values in Table 1 remain tentative and values for a few groups are not available
for both condensed phases.
The calculations for t-butylbenzene using the group values
of Table 1 are fairly straightforward and require no additional
comments. Agreement with experiment for the solid is good.

Estimations of the heat capacity of 5-aminouracil are not
as obvious. This compound can be modeled as containing
two cyclic secondary amides, a cyclic tertiary and cyclic quaternary sp2 carbon atom and a primary sp3 nitrogen. Less
intuitive models include modeling the ring as a cyclic urea
and cyclic ketone or as a cyclic imide and cyclic secondary
amine along with a cyclic tertiary and cyclic quaternary sp2
carbon atom. All three of these estimations are illustrated in
Table 2. All are in reasonable agreement with the experimental value 关1907ZIE/SZT兴. In this case, the less intuitive models give a slightly better agreement with experiment. Since
group values for liquid cyclic ureas and cyclic imides are not
available and cannot be used for the vaporization and fusion
enthalpy temperature adjustments described below, the value
for the more intuitive model should probably be used for
fusion enthalpy adjustments. The heat capacity of
5-aminouracil can also be evaluted as its tautomer, 2,4dihydroxy-5-aminopyrimidine. For comparative purposes,
this estimation is also included in the table. In this case, the
heat capacity of the solid is reproduced reasonably well but a
larger discepancy is observed between the predicted heat capacities of the liquid. In addition to 5-aminouracil, the heat
capacities of a number of other solid uracils are reported in
the same article 关1907ZIE/SZT兴: uracil 共estimated: 124.6;
expt: 131.8兲; 6-aminouracil 共estimated: 135; expt: 147.0兲,

differ slightly from those reported by the authors of the article who used the same method but different groups to
model the tertiary and quaternary sp2 carbon groups
关1907ZIE/SZT兴.
Calculations for 2,9-dimethyl-1,10-phenanthrolene are
fairly straightforward and in good agreement with the experimental heat capacity of the solid 关2007BON/CAT兴. The authors of this work also report the heat capacity of solid 1,10phenanthrolene as 115 J mol−1 K−1 at T = 298.15 K. The
estimated value for the solid at this temperature is
201.4 J mol−1 K−1 共calculations not shown兲. In this case the
experimental value appears to be remarkably small when
compared to the estimated value and to the value of naphthalene, 165 J mol−1 K−1 共300 K兲, used as a standard.
Other group additivity methods of varying complexity
have been reported for the estimation of C p,m共l , 298.15 K兲.
References for these and an alternative method for calculating heat capacities can be found in the recent work of Kolska
et al. 关1908KOL/KUK兴.

2.2. Vaporization enthalpies
Equation 共2兲 is an equation derived to model the differences in heat capacity between the liquid and gas phases
关1993CHI/HOS兴. It has been derived by correlating vaporization enthalpy differences measured at temperature T and
generally at T = 298.15 K with the heat capacity of the corresponding liquid at T = 298.15 K for which reliable vaporization data are available. The vaporization enthalpy data
used were obtained from the critical review and data compilation of Majer and Svoboda 关1993CHI/HOS兴. It has been
found to provide satisfactory results for adjustments ranging
from approximately T = 500 to 250 K 关1998CHI, 1999SAB/
XU, 2008ROU/TEM兴. The adjustments have been generally
been applied from the mean temperature of measurement, T̄,
to 298.15 K. Adjustments for temperatures above T = 500 K
should be viewed with caution,

2.3. Sublimation enthalpies
Sublimation enthalpies can also be adjusted to T
= 298.15 K from the mean temperature of measurement using a similar relationship, Eq. 共3兲. This equation has also
been derived by correlating sublimation enthalpy differences
measured at temperature T̄ and generally at T = 298.15 K
with the estimated heat capacity of each corresponding crystalline compound at T = 298.15 K 关1993CHI/HOS兴. Unlike
vaporization enthalpy data, much less critically evaluated
sublimation enthalpy data are available. As a consequence, a
larger uncertainty is associated with this adjustment,

Many compounds do not exhibit solid-solid phase transitions
at temperatures below fusion. For those compounds that do,
the enthalpy of the transition also needs to be added to the
fusion enthalpy when using Eq. 共1兲 if the sublimation enthalpy was measured at temperatures below the transition
temperature Ttrns. If the sublimation enthalpy was measured
above T = Ttrans, the fusion enthalpy can be used directly in
Eq. 共1兲 to reproduce the sublimation enthalpy. If Ttrans exceeds T = 298.15 K, then the transition enthalpy will need to
be added to the sublimation enthalpy to obtain

The term 关C p,m共s , 298.15 K兲兴 refers to the molar heat capacity of the solid phase at T = 298.15 K. The relationship was
derived using solid heat capacities estimated by the group
additivity method described above 关1993CHI/HES兴. This
equation has also been found to give satisfactory results for
temperatures up to approximately T = 500 K. Group values
used in these estimations are also summarized in Table 1. As
with heat capacities of the liquid state, experimental heat
capacity values can be substituted for C p,m共s , 298.15 K兲 if
available. When using Eq. 共3兲, an uncertainty equal to onethird the magnitude of the total temperature adjustment
should be assumed. While this uncertainty, arbitrarily chosen, is significant, some compensation is afforded by the fact
that temperature adjustments of sublimation enthalpies are
generally much smaller than the corresponding adjustments
for vaporization enthalpies. In cases where the experimental
sublimation enthalpy is reported by the author at T
= 298.15 K, the reader should consult the original literature
to determine how the temperature adjustment was achieved.
A number of different methods have been used in the literature for this adjustment and it has been found that some
methods provide more thermodynamically consistent results
than others when using Eq. 共1兲 关1998CHI兴.
2.4. Fusion enthalpies
Temperature adjustments for fusion enthalpies from Tfus to
T = 298.15 K can be achieved by noting that if Eq. 共2兲 is
subtracted from Eq. 共3兲, the heat capacity of the gas phase
common to both cancels and the remainder results in the
difference in molar heat capacity between the liquid and
solid phases, ⌬Cp共cr, l兲, Eq. 共4兲. Equation 共4兲 has been sucJ. Phys. Chem. Ref. Data, Vol. 39, No. 4, 2010
2.5. Sample phase change enthalpy adjustment to
T = 298.15 K
A few examples serve to illustrate the usefulness of Eqs.
共1兲–共4兲 when all three phase change enthalpies data for a
particular substance are available. These are shown in Table
3. The first example, cyclohexanone, illustrates the use of
these equations for temperature adjustments below ambient
temperature. Cyclohexanone exhibits a solid-solid phase
transition at a temperature below the temperature range used
in the sublimation enthalpy measurement and hence is not
included in Eq. 共1兲. Since the heat capacity of the liquid
generally exceeds that of the solid phase, adjustment to T
= 298.15 K in this case actually increases the fusion enthalpy
from 1.3 to 3.0 kJ mol−1. Three vaporization enthalpies have
been reported, in good agreement with each other when adjusted to the reference temperature. The sublimation enthalpy, when adjusted to the reference temperature, is attenuated slightly, since the heat capacity of the solid generally
exceeds that of the gas phase. The sublimation enthalpy,
48.2⫾ 0.3 kJ mol−1, is within experimental error of the mean
value calculated using Eq. 共1兲, 49.4⫾ 0.8 kJ mol−1. The uncertainty in the latter value is the mean uncertainty associated with each entry, and for one of the entries, the uncertainty associated with only the temperature adjustment.
Phenacetin illustrates a situation not uncommon with pharmaceuticals, the possible existence of polymorphism. The
fusion enthalpy of phenacetin has been reported a number of
times. Most reports are in reasonable agreement with each
other except for one. In this case, the value is probably in
error since the first and fourth fusion enthalpy entries, which
are in disagreement, have been reported by the same research
group. Ignoring the fourth value, an average value of
25.2⫾ 1.8 kJ mol−1 is calculated, which when added to the
PHASE TRANSITION ENTHALPY MEASUREMENTS
vaporization enthalpies results in two values, one of which
appears to be in much better agreeement with a single determination of the sublimation enthalpy. The uncertainty in
⌬fusHom共298 K兲 only reflects the uncertainty in the temperature adjustments.
Carbazole is another example of a substance that exhibits
a solid-solid phase transition. In this case the fusion enthalpy
at T = 298.15 T should include this transition since the subli-
043101-7
mation enthalpy was measured at a temperature below the
transition. A solid to liquid total phase change enthalpy of
15.6⫾ 3.5 kJ mol−1 is obtained which when added to the vaporization enthalpy results in sublimation enthalpy values of
97.9⫾ 5.1 and 91.8⫾ 3.5 kJ mol−1. In this instance, only one
of the sublimation enthapy values calculated in this manner
is consistent with the two sublimation enthalpies measured
directly.

3. The Phase Change Enthalpy
Compendium
The phase change enthalpy data reported in this compendium have been reported over the time period of 1880–2010.
The data are combination of three compendia published in
recent years and updated to the present 关1902CHI/ACR,
2003CHI/ACR, 2003CHI/ACR2, 1999CHI/ACR, 1909CHI/
ACR兴. Vaporization enthalpies and sublimation enthalpies
have been measured for many years and numerous tech-
niques have been developed to do so. Generally, these techniques can be categorized into two groups, calorimetric techniques, in which the phase change enthalpy is measured
directly, and techniques in which vapor pressure is measured
directly or indirectly as a function of temperature. Providing
on the experimental setup, calorimetric methods can also
provide vapor pressures if an effusion cell is used. More
recently, gas chromatographic techniques have also been developed to measure vaporization enthalpies. These techniques can provide both vaporization enthalpies and liquid

vapor pressures but since standards must be used, some care
must be used in assessing their reliability. One technique,
referred to as correlation-gas chromatography, has been
shown to be successful provided standards are chosen with
reliable values and appropriately related functional groups
关2009LIP/HAN兴. Fusion enthalpies have generally been
measured by some form of calorimetry. These techniques are
described by a number of acronyms used throughout the
tables. A summary of these acronyms and their meanings can
be found in Table 4.
In some cases, the vapor pressure–temperature data reported in the literature authors were analyzed by using the
Clausius Clapeyron relationship, Eq. 共5兲, where C = 0, by the
authors. The “Handbook of the Thermodynamics of Organic
Compounds,” by Stephenson and Malanowski 关1987STE/
MAL兴, was a useful source of vaporization enthalpy information provided in the form of Antoine Constants. Unfortunately, references to the original literature data are not
provided by these authors. Vaporization enthalpies and some
sublimation enthalpies were calculated from the A, B, and C
constants reported in this compendium using Eq. 共6兲,

Phase change enthalpies for organic compounds are reported
in Tables 5–11. Organometallic compounds are reported in
Table 12. Organometallic compounds are arranged alphabetically according to the metal.
In Tables 5–12, some enthalpy values are cited without a
reference on the same line. The appropriate reference can be
found with the next value with a reference 共multiple enthalpy
values were taken from the same source兲. In addition, in
Tables 5–12, where a value is prefixed with a “U” 共e.g., “U
