Critical Evaluation:
The 1,2-dichloropropane (1) and water (2) binary system is treated in two parts; part 1 is 1,2-dichloropro-pane (1) in water (2) and part 2 is water (2) in 1,2-dichloropropane (1).
Part 1.
The solubility of 1,2-dichloropropane (1) in water (2) has been studied by 15 work groups in the temperature range from 275 to 313 K. The data of Chiou et al.
1
are markedly higher than the solubility values calculated from the smoothing equation and are therefore rejected. The measurements of McNally and Grob
2,3
and of Howe et al.
4
are significantly lower than other solubility data and are also rejected.
The remaining data from eleven laboratories were compiled or used for the smoothing equation. The combined measurements of Gross,

of Wright and Schaffer,

of McClure,

of McGovers,

of Chitwood,

of Dreisbach,

of Sato and Nakijima,

of Leighton and Calo,

of Mackay et al.,

of Warner et al.,

and of Wright et al.

were correlated to obtain the following mass percent (1) equation:
Solubility [100 w
1
] = 3.3285 - 0.021464 (T/K) + 3.7632x10
-5
(T/K)
2
which yielded a standard deviation of 8.56x10
-3
in the temperature range from 275 to 313 K. The curve obtained from the smoothing equation shows a distinct minimum of 285.18 K as shown in
Fig. 3
..
The recommended solubility values at 5 K intervals for 1,2-dichloropropane in water in weight percent and mole fraction are presented in Table 12.
Part 2.
The solubility of water (2) in 1,2-dichloropropane (1) has been reported in five sources covering the narrow temperature range from 293 to 298 K. The data are in very poor agreement and in the absence of other independent studies, it is not possible to determine which values are more reliable. Further studies will be necessary before even tentative values can be prescribed. All the available data for the solubility of water (2) in 1,2-dischloropropane (1) in weight percent and mole fraction are summarized in Table 13.
