EC number: 269-646-0 | CAS number: 68308-34-9 The complex combination of hydrocarbons obtained by the thermal decomposition (at 399°C (750°F) or higher) of kerogen. It consists of hydrocarbons and heterocyclic compounds containing nitrogen, sulfur or oxygen.
Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Not reported
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study conducted in compliance with agreed protocols, with no or minor deviations from standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- no
- GLP compliance:
- not specified
- Type of method:
- other: Modified Watson Correlation
- Temp.:
- 25 °C
- Vapour pressure:
- 64.6 Pa
- Conclusions:
- The vapour pressure of Shale Oil was estimated to be 64.6 Pa at 25 °C.
- Executive summary:
The vapour pressure of the test material was investigated in a study which was conducted in accordance with the standardiosed guideline OECD 104, using the Modified Watson Correlation.
Under the conditions of the study, the vapour pressure of Shale Oil was estimated to be 64.6 Pa at 25 °C.
Reference
The experimentally determined boiling point of Shale Oil is 458 K or 185°C.
The vapour pressure of Shale Oil was estimated to be 6.46 x 101 Pa at 25 °C based on experimentally determined boiling point and using the Modified Watson Correlation. According to the guideline, the dynamic method would be suitable for this vapour pressure range and usually pure substances are required. However, since the test item is a complex mixture of different compounds, the dynamic method is not applicable.
Description of key information
The vapour pressure of Shale Oil was estimated to be 64.6 Pa at 25 °C.
Key value for chemical safety assessment
- Vapour pressure:
- 64.6 Pa
- at the temperature of:
- 25 °C
Additional information
The vapour pressure of the test material was investigated in a study which was conducted in accordance with the standardiosed guideline OECD 104, using the Modified Watson Correlation. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
Under the conditions of the study, the vapour pressure of Shale Oil was estimated to be 64.6Pa at 25 °C.
