The binary system of trans-1,2-dichloroethene (1) and water (2) binary system
is treated in two parts; part 1 is trans-1,2-dichloroethene (1) in water (2)
and part 2 is water (2) in trans-1,2-dichloroethene (1).
Part 1. The solubility of trans-1,2-dichloroethene (1) in water (2)
has been studied by six groups of workers in the narrow temperature range from
283.15 to 313.15 K. Both the measurements of McGovern1 and those
of Sato and Nakijima2 are noticeably higher than the likely solubility
and are rejected. The solubility determinations of Howe et al.3
tend to appear low in general, as discussed in the critical evaluation of solubilities
of CCl3F, CCl4, CHBr2Cl, CHCl3,
CH2Cl2, and cis-1,2-CHCl=CHCl in water, and they are also
rejected.
The remaining solubility data of Gossett,4 Warner et al.,5 and Wright et al.6 were used to obtain by regression the following
mass percent (1) equation:
Solubility [100 w1]
= 7.803906 – 4.5457 × 10–2 (T/K) + 6.96755
× 10–5 (T/K)2.
This equation represents the combined
data points and it yields a standard deviation of 2.72 × 10–2
in the temperature range from 283.15 to 313.15 K. The tentative values of solubility
at 5 K intervals for trans-1,2-dichloroethene (1) in water (2) are presented
in Table 1 on the following page.
The weight percent (1) observed values and the curve obtained from the smoothing equation are shown in Fig. 9.
Part 2. The solubility of water (2) in trans-1,2-dichloroethylene (1)
has been studied only by McGovern1 and there are no other measurements
for comparison. Therefore, it is not possible to perform a critical evaluation.
