The 1,1,1,2-tetrachloroethane (1) and water (2) binary system is treated in
two parts; part 1 is 1,1,1,2-tetra-chloroethane (1) in water (2) and part 2
is water (2) in 1,1,1,2-tetrachloroethane (1).
Part 1. The solubility of 1,1,1,2-tetrachloroethane (1) in water (2)
has been studied by five groups of workers in the temperature range from 273.15
to 323.15 K. There is a reasonable agreement among the reported results except
for those of Chiou and Freed1 whose measurements are markedly lower
than other data and are therefore rejected.
The combined data of van Arkel and Vles,2 Walraevens et al.,3 Sato and Nakijima,4 and Weight et al.5 were correlated
to obtain the following mass percent (1) equation:
Solubility [100 w1 = 2.17896 – 1.3966 × 10–2 (T/K) + 2.35307 × 10–5 (T/K)2,
which shows a standard deviation of 4.97 × 10–3 in the temperature range from 273.15 to
323.15 K.
The measurements and the curve obtained from the smoothing equation are shown
in Fig. 10. The curve shows a distinct minimum at 296.76 K. The appearance
of the solubility minimum for aqueous hydrocarbon systems is discussed in the
Preface.
The recommended solubility values at 5 K intervals for 1,1,1,2-tetrachloroethane
(1) in water (2) are presented in Table 1.
Part 2. The solubility of water (2) in 1,1,1,2-tetrachloroethane has
been reported in one paper. Only the data of Staverman6 are available
for the solubility of water in 1,1,1,2-tetrachloroethane and so no critical
evaluation is possible. These data are classified as tentative. For further
details the reader is referred to the relevant Compilation.
