Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2020
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM D2879-97 (2007) Standard Test Method for Vapour Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope
- Deviations:
- yes
- Remarks:
- A digital electronic pressure gauge and not a mercury manometer (as stipulated in ASTM D2879 - 97 2007) was used for pressure measurement.
- GLP compliance:
- no
- Type of method:
- isoteniscope
- Specific details on test material used for the study:
- The test item, 2-propen-1-amine, N-2-propenyl-, hydrochloride, is supplied as an aqueous solution. In order to perform the phys-chem testing, the water was removed to produce a crystalline deliquesce solid.
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 0.464 mm Hg
- Conclusions:
- A vapour pressure of 0.464 mm Hg at 20 °C was determined for 2-propen-1-amine, N-2-propenyl-, hydrochloride.
- Executive summary:
The ASTM D2879 - 97 Standard Test Method for Vapour Pressure-Temperature Relationship and Initial Decomposition of Liquids by Isoteniscope was followed to determine the vapour pressure of test substance 2-propen- -amine, N-2-propenyl-, hydrochloride. The test substance was determined to have a vapour pressure of 0.464 mm Hg 20 oC based on three runs.
Reference
| Vapour Pressure at 20 oC/ mm Hg | |
| Run 1 | 0.462 |
| Run 2 | 0.465 |
| Run 3 | 0.464 |
| Average | 0.464 |
Description of key information
The ASTM D2879 - 97 Standard Test Method for Vapour Pressure-Temperature Relationship and Initial Decomposition of Liquids by Isoteniscope was followed to determine the vapour pressure of test substance 2-propen- -amine, N-2-propenyl-, hydrochloride. The test substance was determined to have a vapour pressure of 0.464 mm Hg 20 oC based on three runs. This is equivalent to 61.86 Pa at 20oC.
Key value for chemical safety assessment
- Vapour pressure:
- 61.86 Pa
- at the temperature of:
- 20 °C
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.
