The dibromomethane (1) and water (2) binary system is discussed in two parts; part 1 is dibromomethane (1) in water (2) and part 2 is water (2) in dibromomethane (1).
Part 1. The solubility of dibromomethane (1) in water (2) has been studied by 6 workers. The Compilation Sheets immediately follow this Critical Evaluation.The experimental data of all investigators in the 273 to 323 K temperature range are sufficiently reliable for use in the smoothing equation (see Figure 1) with the exception of the experimental work of Booth and Everson (ref. 1) which is markedly higher than other results and is therefore rejected. The combined data of 5 laboratories were correlated to give the following equation for mass per cent (1) solubility:
which produced a standard deviation of 4.4 × 10-2. This equation represents the combined solubility data with a maximum deviation of 6.0% (usually less) and may be considered recommended to represent the data in the 273 to 323 K temperature interval.
The recommended mass per cent solubility values at 5 K intervals for dibromomethane (1) in water (2) are recorded in Table 1.
Part 2. The solubility of water (2) in dibromomethane (1) has been reported in one work (ref.2) and, therefore, no Critical Evaluation has not been performed. The readers are referred to the relevant Compilation Sheet.
