Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 02 July - 21 July, 2009
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The study has been performed according to OECD and/or EC guidelines, and according to GLP principles.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- effusion method: by loss of weight or by trapping vaporisate
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- < 1.33 Pa
- Conclusions:
- The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of HXL-8366.
The vapour pressure of the test substance at 20°C (293K) was < 1.33 x 10-8 Pa = < 1.00 x 10-10 mm Hg.
Reference
The weight loss of the test substance at 210°C, 220°C, 230°C and 240°C was lower than the weight loss of benzo(ghi)perylene at the same temperatures. From this, it was concluded that the vapour pressure of the test substance is < 1.33x10 -8 Pa = <1.00x10 -10 mm Hg.
Description of key information
The vapour pressure of the test substance at 20°C (293K) was < 1.33 x 10-8 Pa = < 1.00 x 10-10 mm Hg.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 20 °C
Additional information
The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure of HXL-8366.
The vapour pressure of the test substance at 20°C (293K) was < 1.33 x 10-8 Pa = < 1.00 x 10-10 mm Hg.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
