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:
- April 2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM D2879 - 97 (2007) Standard Test Method for Vapour Pressure-Temperature Relation ship 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
- Key result
- Temp.:
- 20 °C
- Vapour pressure:
- < 0.002 mm Hg
- Conclusions:
- A vapour pressure < 0.002 mmHg at 20°C was determined for 4,4’-isopropylidenediphenol, reaction products with 1-chloro-2,3-epoxypropane, mono, di and triesters with acrylic acid.
- Executive summary:
The ASTM D2879 - 97 Standard Test Method for Vapour Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope was followed to determine the vapour pressure of test substance 4,4’-isopropylidenediphenol, reaction products with 1-chloro-2,3-epoxypropane, mono, di and triesters with acrylic acid. The test substance was determined to have a vapour pressure < 0.002 mmHg at 20°C based on three runs. This is equivalent to a vapour pressure < 0.27 Pa at 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.
