Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Water solubility and the activity coefficient at infinite dilution are calculated from liquid-liquid contacting until saturation of an aqueous layer. A further experiment, involving stripping of a solute from a non-saturated aqueous solution by an air stream, provides a value equivalent to activity coefficient at infinite dilution multiplied by vapour pressure. By using values obtained from both experiments, vapour pressure can be deduced.
- GLP compliance:
- not specified
- Type of method:
- other: Stripping experiments.
