Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:

Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other: Estimation method
Principles of method if other than guideline:
Vapour pressure estimated by two theoretical methods. In the first instance the vapour pressure was predicted using a predicted melting point
temperature (353°C) as a worst-case value for the boiling point. In the second case the minimum boiling point to achieve a pressure above a threshold (> 10-5 pa) was determined by iteration.
GLP compliance:
yes
Type of method:
other: Estimation
