Critical Evaluation:
The 1,1,2,3,4,5,5,5-octachloro-1,3-pentadiene (1) and water (2) binary system is treated in two parts; part 1 is 1,1,2,3,4,5,5,5-octachloro-1,3-pentadiene (1) in water (2) and part 2 is water (2) in 1,1,2,3,4,5,5,5-octa-chloro-1,3-pentadiene (1).
Part 1.
The solubility of 1,1,2,3,4,5,5,5-octachloro-1,3-pentadiene (1) in water (2) has been studied by two work groups from the same laboratory. The data at the lower temperatures appear to be inconsistent with the single high temperature value. Whether or not the two sets of data at different temperatures are consistent still must be established. The temperature dependence of the solubility observed by Simonov et al.
1
in the 313 K range is considerably higher than that of Antropov et al.
2
Nevertheless, there are insufficient independent data at present to justify exclusion of any values and thus all solubility results in weight percent and mole fraction are included in Table 26. In view of the lack of better consistency between the two sets of measurements, the listed values should be regarded as very tentative. The temperature dependence of the solubility of 1,1,2,3,4,5,5,5-octachloro-1,3-pentadiene (1) in water (2) requires a thorough investigation over the whole temperature range in order to establish more reliable values.
Part 2.
The solubility of water (2) in 1,1,2,3,4,5,5,5-octachloro-1,3-pentadiene (1) has been reported by the same investigators who studied the solubility of 1,1,2,3,4,5,5,5-octachloro-1,3-pentadiene (1) in water (2).
The data consistency was studied by plotting log
10
x
2
versus the reciprocal of absolute temperature; see
Figure 9
. The plot shows that the temperature dependence of the solubility observed by Antropov et al.
2
and by Simonov et al.
1
is sufficiently consistent over the temperature range from 291 to 313 K. Nevertheless, there are insufficient independent data at present to justify the recommendation of any values. All the reported values were correlated with the smoothing equation between 291 and 313 K:
log
10
x
2
= 5.2285 - 3113.03/(T/K)
This equation yielded a standard deviation of 2.18x10
-2
in the temperature range from 291 to 313 K.
A linear relation between the solubility expressed as log
10
x
2
versus the reciprocal of absolute temperature is apparent in
Fig. 9
. The straight line behavior of such plots is characteristic of the solubility of water in halogenated hydrocarbons; this behavior is discussed in the Preface in greater detail.
