Critical Evaluation:

The diiodomethane (1) and water (2) binary system is discussed in two parts; part 1 is diiodomethane (1) in water (2) and part 2 is water (2) in diiodomethane (1).

Part 1. The solubility of diiodomethane (1) in water (2) has been studied by four groups of workers. The experimental data of Gross and Saylor (ref. 1) and Andrews and Keefer (ref. 2) are supported by the descriptions of the methods used for determining the reported data. Details are not available for methods, apparatus, and procedures used by van Arkel and Vles (ref. 3) and O'Connell (ref. 4) for obtaining the solubility data.

The three solubility values, see (refs. 1, 3, and 4), between 293.15 and 303.15 K compare favorably with the selected value, whereas the datum of Andrews and Keefer (ref. 2) at 298.15 K is low and classified as doubtful. More accurate solubility determinations are required, meanwhile, the tentative mass per cent solubility of diiodomethane (1) in water (2) at 303.15 K.

Part 2. The only datum available for the solubility of water (2) in diiodomethane (1) is that of Hutchison and Lyon (ref. 5) and so no Critical Evaluation is possible. The interested reader is referred to the relevant Compilation Sheet for the experimental solubility.
