- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- March 2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:

- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Version / remarks:
- 2006
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- dynamic method
- Temp.:
- 20 °C
- Vapour pressure:
- 15 Pa
- Remarks on result:
- other: calculated based on the lowest possible boiling temperature
- Vapour pressure:
- 120 Pa
- Remarks on result:
- other: calculated based on the lowest possible boiling temperature
- Conclusions:
- The test item dihexyl ether has a vapout presure of 15 Pa at 20°C and 120 Pa at 50°C (the calcualtion is based on the lowest possibleboiling temperature) according to the definitions inthe oECD Guideline 104 (Grain-Watson estimation).
- Executive summary:
The vapour pressure of dihexyl ether was determined in accordance with the test method OECD Guideline 104. The experimentally determined vapour pressure of dihexyl ether at 20°C is not in the recommended range of 1 to 1000 mbar for DCS-measurements. therefore as estimation procedure in accordance was used (Grain Watson Method). This method is applied for vapour pressures between 10(exp3) to 10(exp-7) mbar. According to the study dihexyl ether has a vapour pressure of 5 Pa at 20 °C and 120 Pa at 50 °C.
Reference
Description of key information
The vapour pressure of a dihexyl ether is 15 Pa at 20 °C and 120 Pa at 50 °C, respectively.
Key value for chemical safety assessment
- Vapour pressure:
- 15 Pa
- at the temperature of:
- 20 °C
Additional information
The vapour pressure of dihexyl ether was determined according to the Dynamic Method. Based on the experimental values the vapour pressure for 20 and 50 °C was calculated to be 15 and 120 Pa, respectively.
