Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Vapour pressure
Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- vapour pressure was determined with an apparatus of Washburn and Heuse, modified by Bacarella, Finch and Grunwald. In a stream of dry nitrogen is allowed to flow consecutively over the liquid in a number of saturator tubes which are being continually rocked. The resultant nitrogen stream is then passed through a cold trap to condense the organic vapors from it. In determining the vapor pressure of pure liquids the contents of the cold trap were sometimes weighed and sometimes analyzed spectrophotometrically.
- GLP compliance:

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.
