Reference
Endpoint:
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Reference:
Composition 0
Qualifier:
no guideline followed
Principles of method if other than guideline:
The vapor pressures were measured by means of a dynamic method with an ebulliometer. With this equipment, vapor pressures of pure components can be experimentally determined in a temperature range from approx. 250 to 600 K and at pressures from about
1 mbar up to 1 bar. At a given pressure (regulated by an electronic pressure control), the boiling temperatures of a component are measured. Due to the volume of the equipment only small amounts of the substances (about 20 ml) are needed.
