- Version / remarks:
- adopted by the Council 2006
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- Deviations:
- no
- Principles of method if other than guideline:
- The vapour pressure is determined by measuring the boiling temperature of the substance at various specified pressures between roughly 10 to
approx. 10³ hPa. The apparatus consists of a tube with a boiling section (by electrical heating) in the lower part, a cooler in the middle part, and an
outlet to a pressure regulation system in the upper part. The thermometer is placed in the vapour above the surface of the liquid. The temperature of the vapour is measured as a function of the pressure. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- dynamic method
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0.013 hPa
- Remarks on result:
- other: The vapour pressure at 20 °C was calculated by mathematical extrapolation using the Antoine equation.
- Temp.:
- 25 °C
- Vapour pressure:
- 0.021 hPa
- Remarks on result:
- other: The vapour pressure at 25 °C was calculated by mathematical extrapolation using the Antoine equation.
- Conclusions:
- The vapour pressure of Isobornyl acrylate was determined according to OECD guideline 104 [adopted 2006] and EU test method A.4
with the dynamic method. The vapour pressure was: 0.013 hPa at 20°C - Executive summary:
The vapour pressure of Isobornyl acrylate was determined according to OECD guideline 104 [adopted 2006] and EU test method A.4 with the dynamic method.
The vapour pressure was: 0.013 hPa at 20°C
Reference
The vapour pressure was measured with the dynamic method: temperature range of 90 °C to 148 °C.
The following table shows the measured vapour pressure at the corresponding temperatures:
| Temperature [°C] | Vapour pressure [hPa] |
| 102.06 | 6.4 |
| 109.30 | 10.2 |
| 116.65 | 16.0 |
| 122.18 | 20.2 |
| 127.46 | 26.1 |
| 130.68 | 30.0 |
| 136.12 | 38.2 |
| 142.68 | 50.0 |
| 147.77 | 60.6 |
