Critical Evaluation:

        The cis-1,2-dichloroethene (1) and water (2) binary system is treated in two parts; part 1 is cis-1,2-dichloroethene (1) in water (2) and part 2 is water (2) in cis-1,2-dichloroethene (1).
      Part 1. The solubility of cis-1,2-dichloroethene (1) in water (2) has been investigated by five groups of workers in the narrow temperature range from 283.15 to 313.15 K. The data of Howe et al.¹ are markedly lower than other results and are therefore rejected. The solubility determinations of Howe et al.¹ have been found to give lower values in general, as discussed in the critical evaluation of solubilities of CCl₃F, CCl₄, CHBr₂Cl, CHCl₃, and CH₂Cl₂ in water. Both the measured values of McGovern² and those of Sato and Nakijima³ are noticeably low and were not used for the smoothing equation.
     The combined data of Gossett⁴ and Wright et al.⁵ were correlated to obtain the following mass percent (1) equation:

Solubility [100 w₁] = 27.7353 – 0.178316 (T/K) + 2.93282 × 10^–4 (T/K)²,

which yielded a standard deviation of 5.32 × 10^–2 in the temperature range from 283.15 to 313.15 K. The above equation represents the combined data with maximum deviation of 12 %, usually less, and may be considered tentative for solubility of cis-1,2-dichloroethene in water. The tentative values for this system are given in Table 1, as smoothed values at 5 K intervals. The curve obtained from the smoothing equation shows a distinct minimum at 304 K as shown in Fig. 8 which presents the data and calculated values versus temperature. The appearance of the solubility minimum is discussed in the Preface.
Part 2. The solubility of water (2) in cis-1,2-dichloroethene (1) has been studied by McGovern² and Ohtsuka and Kazama⁶ between 273.15 and 298.15 K. The solubility data of McGovern² are believed to be more reliable than that of Ohtsuka and Kazama⁶ because McGovern made measurements at more than one temperature. However, the datum at 298.15 K is a misprint, and it should be read as 0.055 [100 w₂]. These data are classified as tentative and are listed in Table 2.
