Critical Evaluation:

        The 1,1,2-trichloroethane (1) and water (2) binary system is treated in two parts; part 1 is 1,1,2-trichloro-ethane (1) in water (2) and part 2 is water (2) in 1,1,2-trichloroethane (1).
     Part 1. The solubility of 1,1,2-trichloroethane (1) in water (2) has been studied by 16 groups of workers in the temperature range from 273.15 to 328.15 K. The results of only two groups were not used in the data smoothing procedure. The solubility data of Wright and Schaffer1 and Veight et al.2 are significantly lower than other results and are therefore rejected. Even though there appears to be some inconsistency in the reported solubility data of Leighton and Calo3 and Howe et al.,4 that is, the former does not give a minimum and the latter shows a maximum in solubility, the combined results of 14 laboratories have been used for the smoothing equation. The data of van Arkel and Vles,5 McGovern,6 Treybal et al.,7 Newman et al.,8 Walraevens et al.,9 Sato and Nakijima,10 Coca and Diaz,11 Coca et al.,12 Newsham,13 Leighton and Calo,3 McNally and Grob,14 Barr and Newsham,15 Howe et al.,4 and Wright et al.16 were included to obtain the following mass percent (1) equation:

Solubility [100 w1] = 2.89796 – 1.8585 ×l 10–2 (T/K) + 3.48961 × 10–5 (T/K)2,

which shows a standard deviation of 3.41 × 10–2 in the temperature range from 273.15 to 328.15 K. The above equation represents the combined data with maximum deviation of 15 %, usually less, and may be considered tentative for solubility if 1,1,2-trichloroethane in water.
     The measurements and the curve obtained from the smoothing equation are shown in Fig. 15.  A solubility minimum does not appear in the temperature range involved. Additional details concerning the presence of a solubility minimum for aqueous hydrocarbon systems are provided in the Preface.
     The tentative values for this system are given in Table 1 as smoothed values at 5 K intervals.
     Part 2. The solubility of water (2) in 1,1,2-trichloroethane (1) has been studied by six groups of workers in the temperature range from 264.15 to 323.15 K. The data of Coca and Diaz11 and Coca et al.12 are several per cent lower than the smoothed solubility values and are therefore rejected. Both results seem to be reported from the same laboratory with some discrepancy between the two data values.
     The remaining data of Staverman,17 McGovern,6 Treybal et al.,7 and Barr and Nesham15 were compiled or used for the smoothing equation. The fitting equation used was:

log10 x2 =  2.48799 – 1356.67/(T/K).

This equation yielded a standard deviation of 6.99 × 10–2 in the temperature range from 264 to 323 K. The recommended solubilities at 5 K intervals for water in 1,1,2-trichloroethane are presented in Table 2.
     Measured values and the curve obtained from the smoothing equation for solubility expressed as log10 x2 versus the reciprocal of absolute temperature are shown in Fig. 16.
