Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Migrated phrase: estimated by calculation
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: acceptable calculation method
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Vapor Pressure is estimated by calculation. Three methods are employed; all three methods use the boiling point.
1.) Antoine method (reference: Chapter 14 of W.J. Lyman's book "Handbook of Chemical Property Estimation Methods", Washington, DC: American Chemical Society, 1990).
2.) Modified Grain method (reference: Page 31 of Neely and Blau's Environmental Exposure from Chemicals, Volume I, CRC Press, 1985)
3.) Mackay method (reference: Page 31-2 of Neely and Blau's Environmental Exposure from Chemicals, Volume I, CRC Press, 1985).
For solids, a melting point is required to adjust the vapor pressure from a subcooled (supercooled) liquid to a solid. - Type of method:
- other: calculation
- Temp.:
- 25 °C
- Vapour pressure:
- 0.001 Pa
- Remarks on result:
- other: EPISUITE estimation (modified Grain Method), value for liquids
- Executive summary:
Vapour pressure of octanoic acid, monoester with glycerol was estimated to be 0.00116 Pa at 25°C using US EPA EPI Suite 4.11. Principle of calculation is the modified Grain method. Result is calculated for liquids (subcooled liquid VP).
