Solubility System: Dibromochloromethane with Water

Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Dibromochloromethane; CHBr2Cl; [124-48-1]  NIST Chemistry WebBook for detail

Evaluator:

Critical Evaluation:


All the available solubility data for dibromochloromethane (1) in water (2) are summarized in Table 1.

The data are in very poor agreement. Considerable discrepancies exists even between the two solubility values reported by the same workers, compare (ref. 2) and (ref. 3). In the absence of further independent studies it is not possible to determine which value is the more reliable. Additional investigations will be necessary before even tentative values can be assigned. Even so, it may be noted that the solubility trend for halogenated hydrocarbon - water systems, as presented in the Preface, provided some support for the mass per cent (1) value, 100 w₁, of 0.8124 at 298.15 K (ref. 1).
