Evaluation
Quantitative solubility data for the o-xylene (1) - water (2) system have been reported in the publications listed in Table 1..

The original data in these publications are compiled in the Data Sheets immediately following this Critical Evaluation. Alwani and Schneider (ref 5) have also reported data on a critical locus at high temperatures and pressures. For convenience further discussion of this system will be given in two parts..


1 SOLUBILITY OF O-XYLENE (1) IN WATER (2)

The high temperature, high-pressure data of Guseva and Parnov (ref 2) and Alwani and Schneider (ref 5) have been obtained under quite different conditions and thus no Critical Evaluation of their data is possible. However, it may be noted that the data of Guseva and Parnov are frequently unreliable. The interested user is referred to the relevant Data Sheets for experimental values.

At atmospheric pressure all the available data are listed in Table 2 except for the value of Krzyzanowska and Szeliga (ref 9) which does not appear to be independent of that of Price a (ref 8) and has therefore been excluded from consideration..

At 298K, the data of McAuliffe (ref 3), Sutton and Calder (ref 7), Price (ref 8) and Sanemasa et al. (ref 10) are in excellent agreement and their average is Recommended. The values of Andrews and Keefer (ref 1) and Polak and Lu (ref 6) are markedly higher (> 3σn) and are rejected.

At other temperatures only the data of Sanemasa et al. (ref 10) are available except for the 273 K datum of Polak and Ly (ref 6). These data are therefore regarded as Tentative.

Selected data are plotted in Figure 1

2 SOLUBILITY OF WATER (2) IN O-XYLENE (1)

The available solubility values for water in o-xylene are listed in Table 3. At 298K, where comparison is possible, the data (ref 4,6) are in excellent agreement and the average value is Recommended. The remaining datum at 273K must be regarded as Tentative in the absence of confirmatory data..

At other temperatures only the data of Sanemasa et al. (ref 10) are available except for the 273K datum of Polak and Ly (ref 6). These data are therefore regarded as Tentative..
