Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Study period:
- 2017-03-16 - 2017-05-30
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- GLP compliance:
- not specified
- Type of method:
- dynamic method
- Specific details on test material used for the study:
- Batch F7356
- Test no.:
- #1
- Temp.:
- 20 °C
- Vapour pressure:
- 144 Pa
- Conclusions:
- The test item has a vapour pressure of 144 Pa at 20 °C
- Executive summary:
The vapour pressure of the test item was determined in accordance with OECD TG 104. An experimental measurement of the vapour pressure by DSC was not practicable. Estimation using the Grain-Watson method was performed using the lowest possible boiling temperature. The estimated vapour pressure is 144 Pa at 20 °C.

Additional information
The vapour pressure of the test item was determined in accordance with OECD TG 104. An experimental measurement of the vapour pressure by DSC was not practicable. Estimation using the Grain-Watson method was performed using the lowest possible boiling temperature. The estimated vapour pressure is 144 Pa at 20 °C.
A measured vapour pressure is available for Phosphoric acid, C4 and C12-14(even numbered) alkyl esters, the parent ester of the ammonium salt. It is considered that the measured value of 0.45 Pa is likely to represent a worse case for the ammonium salt and is adopted for exposure assessment.
