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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Study period:
- 5.5.2009 - 19.6.2009
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 104 (Vapour Pressure Curve)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.4 (Vapour Pressure)
- GLP compliance:
- yes
- Type of method:
- effusion method: by loss of weight or by trapping vaporisate
- Key result
- Test no.:
- #1
- Temp.:
- 20 °C
- Vapour pressure:
- 0 Pa
- Conclusions:
- The isothermal thermogravimetric effusion method was chosen for the determination of the vapour pressure af LDT600 C3. The vapour pressure of the test substance at 20°C (293K) was 2.12 E-8 Pa= 1.59 E-10mm Hg.
Reference
The evaporation rate of the test substance was obtained with a temperature program of above melting temperature of the test substance. According to this the vapour pressure of the test substance (which was, according to the method, extrapolated to 20 °C) could be slightly overestimated.

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.
