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:
Solubility [100 w1] = 10.1890 – 0.06336789 (T/K) +
1.10906 × 10–4 (T/K)2
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.
