Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EPA OPPTS 830.7950 (Vapor Pressure)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- dynamic method
- Temp.:
- 20 °C
- Vapour pressure:
- 0.313 Pa
- Remarks on result:
- other: extrapolated value
- Temp.:
- 25 °C
- Vapour pressure:
- 0.603 Pa
- Remarks on result:
- other: extrapolated value
- Temp.:
- 50 °C
- Vapour pressure:
- 9.43 Pa
- Remarks on result:
- other: extrapolated value
- Conclusions:
- The following extrapolated values wer determined from the experimental data gained from the vapour pressure dynamic method:
20°C: 0.313 Pa
25°C: 0.603 Pa
50°C: 9.43 Pa - Executive summary:
The vapour pressure was measured according to the European Commission Council Regulation (EC) No. 440/2008, Annex, Part A, A.4 and OECD Test Guideline 104 with the dynamic method in the temperature range of 117 °C to 240 °C.
After filling the apparatus with the test item the lowest desired pressure is set and the heating system is switched on. The temperature is measured by a resistance thermometer. Equilibrium is reached when a constant boiling temperature is achieved at a given pressure. After recording this point the pressure is increased step by step and if possible up to
the boiling point.
The following extrapolated values wer determined from the experimental data gained from the vapour pressure dynamic method: 20°C: 0.313 Pa, 25°C: 0.603 Pa, 50°C: 9.43 Pa.
Reference
Above 140 °C the test item started to discolour. At the end of the measurement it had dicoloured from brownish-yellow to dark brown-black. For this reason the measured vapour pressure above 207.1 °C where not taken into account for the final result.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
