Evaluator:
A. L. Horvath, Imperial Chemical Industries Limited, Runcorn, U.K.
Critical Evaluation:
The 1,1,2,2-tetrabromoethane (1) and water (2) binary system is treated in two parts; part 1 is 1,1,2,2-tetra-bromoethane (1) in water (2) and part 2 is water (2) in 1,1,2,2-tetrabromoethane (1).
Part 1.
The solubility of 1,1,2,2-tetrabromoethane (1) in water (2) has been studied by five groups of workers. The Compilation Sheets immediately follow this Critical Evaluation. The approximate datum of Booth and Everson
1
is rejected because the reported solubility is somewhat low as well as only approximate. The datum of Blumberg and Melzer
2
is also rejected because it is significantly higher than the other measurements.
Because the measurements were made at more than one temperature, the solubility data of Gooch
et al
.
3
are believed to be more reliable than the other data by Gross
et al
.
4
and O'Connell.
5
All the data are classified as tentative and listed in Table 1 at 5 K intervals. The solubility values of Gooch
et al
.
3
were smoothed by least squares regression to give the following equation:

Part 2.
A small difference exists between the data of Hutchison and Lyon
6
at 298.15 K and that of Blumberg and Melzer
2
at 302.15 K and O'Connell
5
at 293.15 K. Because it is not possible to say which of the two values is more accurate; therefore, it is suggested that the average of the two is possibly the most accurate, that is, 0.039 [100
