Azeotropic Data for Binary Mixtures
J. Gmehling, J. Menke, J. Krafczyk, K. Fischer, J.-C. Fontaine, and H. V. Kehiaian
Binary homogeneous (single-phase) liquid mixtures having an
extremum (maximum or minimum) vapor pressure P at constant
temperature T, as a function of composition, are called azeotropic
mixtures, or simply azeotropes. The composition is usually expressed
as mole fractions, where x1
for component 1 in the liquid
phase and y1
for component 1 in the vapor phase are identical.
Mixtures that do not show a maximum or minimum are called
zeotropic. A maximum (minimum) of the P(x1
) or P(y1
) curves corresponds
to a minimum (maximum) of the boiling temperature T
at constant P, plotted as a function of x1
or y1
[see T(x1
) and T(y1
)
curves, Types I and III, in Fig. 1]. Azeotropes in which the pressure
is a maximum (temperature is a minimum) are often called
positive azeotropes, while pressure-minimum (temperature-maximum)
azeotropes are called negative azeotropes. The coordinates
of an azeotropic point are the azeotropic temperature TAz
, pressure
PAz
, and the vapor-phase composition y1,Az
 , which is the same
as the liquid-phase composition x1,Az
.
In the two-phase liquid-liquid region of partially miscible (heterogeneous)
mixtures, the vapor pressure at constant T (or the
boiling temperature at constant P) is independent of the global
composition x1
of the two coexisting liquid phases between the
equilibrium compositions x1
′ and x1
″ (x1
′ < x1
″).
The constant vapor pressure (boiling temperature) above the
two-phase region of certain partially miscible mixtures is usually
larger (smaller) than the vapor pressure (boiling temperature) at
any other liquid-phase composition in the homogeneous region.
In this case, the vapor-phase composition is inside the miscibility
gap. Mixtures of this type are called heteroazeotropic mixtures, or
simply heteroazeotropes. (Fig. 1, Type II), as opposed to the other
types of azeotropes, called homoazeotropes.
Only in a few cases partially miscible mixtures present a positive
or negative azeotropic point in the single-phase region, outside
the miscibility gap, similar to the azeotropic points of homogeneous
mixtures (Fig. 1, Types IV and VI).
A few binary mixtures, for example the system perfluorobenzene
+ benzene, may present two azeotropic points at constant
temperature (pressure), a positive and a negative one. They are
called double azeotropic mixtures, or simply double azeotropes.
(Fig. 1, Type V).
The knowledge of the occurrence of azeotropic points in binary
and higher systems is of special importance for the design of distillation
processes. The number of theoretical stages of a distillation
column required for the separation depends on the separation factor
α12
, i.e., the ratio of the Ki
-factors (Ki
= yi
/xi
) of the components
i (i = 1, 2). The required separation factor can be calculated with
the following simplified relation (Reference 1):
	 α12
= K1
/K2
= (y1
/x1
)/(y2
/x2
) = (γ1
P1
s
)/(γ2
P2
s
)	 (1)
where γi
is the activity coefficient of component i in the liquid
phase and Pi
s
is the vapor pressure of the pure component i.
In distillation processes, only the difference between the separation
factor and unity (α12
– 1) can be exploited for the separation.
If the separation factor is close to unity, a large number of theoretical
stages is required for the separation. If the binary system
to be separated shows an azeotropic point (α12
 = 1), the separation
is impossible by ordi­nary distillation, even with an infinitely large
number of stages.
Following eq. (1) azeotropic behavior will always occur in homogeneous
binary systems when the vapor pressure ratio P1
s
/P2
s
is
equal to the ratio of the activity coefficients γ2
/γ1
.
Various thermodynamic methods based on gE
-models (Wilson,
NRTL, UNIQUAC) or group con­tribution methods (UNIFAC,
modified UNIFAC, ASOG, PSRK) can be used for ei­ther calculating
or predicting the required activity coefficients for the components
under given conditions of temperature and composition
(Reference 2).
Because of the importance of azeotropic data for the design of
distillation processes, compilations have been available in book
form for quite some time (References 3-7). The most recent printed
data collection was published in 1994 (Reference 8). A revised
and extended version appeared in 2004 (Reference 9).
A collection of approximately 47,400 zeotropic and azeotropic
data sets, compiled from 6600 re­ferences, are stored in a comprehensive
computerized data bank (Reference 10). The references
from the above-mentioned compilations and from the vapor-liquid
equilibrium part of the Dortmund Data Bank (Reference 11)
were supplemented by references found from CAS online searches,
private communications, data from industry, etc.. Over 24,000
zeotropic data and over 20,000 azeotropic data are available for
binary systems. Nearly 90% of the binary azeotropic data show a
pressure maximum. In most cases (ca. 90%) these are homogeneous
azeotropes, and in ap­proximately 7–8% of the cases heterogeneous
azeotropes are reported. Less than 10% of the data stored
show a pressure minimum. Approximately 21,000 of the data sets
stored were published after 1970.
The table below provides information about azeotropes for 808
selected binary sys­tems. Compounds are listed in the modified
Hill order, with carbon-containing compounds following those
compounds not containing carbon. In columns 1 and 2 are the molecular
formulas of components 1 and 2 written in the Hill convention.
In column 3 the names of the components are given, either a
systematic IUPAC name or a name in ubiquitous use. Columns 4,
5, and 6 contain the azeotropic coordinates of the mixtures: temperature
TAz
, pressure PAz
, and vapor-phase composition y1,Az
. The
explanation of the type of azeotrope (column 7) is given by the
following codes:
O:	 homogeneous azeotrope in a completely miscible system
L: 	 homogeneous azeotrope in a partially miscible system
E: 	 heterogeneous azeotrope
X: 	 pressure maximum
N: 	 pressure minimum
D: 	 double azeotrope
C: 	 system contains a supercritical compound
