Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
boiling point
Type of information:
calculation (if not (Q)SAR)
Remarks:
Migrated phrase: estimated by calculation
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
Justification for type of information:
When heating to above melting point, it appeared that there was some decomposition
In the A16 Autoflammabilty test, there was an endotherm above 58 C suggesting instability.
A boiling point has been estimated as it is unlikely that a meaured figure would be possible to obtain
Reason / purpose for cross-reference:
reference to other study
Qualifier:
equivalent or similar to guideline
Guideline:
other: Stein & Brown method
Principles of method if other than guideline:
using Epiweb software
GLP compliance:
no
Type of method:
other: Modelling
Boiling pt.:
ca. 365 °C
Atm. press.:
ca. 1 atm
Decomposition:
ambiguous
Remarks:
Not predicted

Although heating to high temperature and allowing to cool resulted in discolouration, there is no direct evidence of degradation.

Thermal instability is not predicted, but as with many organic solids, a reliable boiling temperature is not possible to obtain

Conclusions:
When heating to above melting point, it appeared that there was some decomposition
A boiling point has been estimated as it is unlikely that a meaured figure would be possible to obtain
The estimated bpt = 365 C
Executive summary:

Although heating to high temperature and allowing to cool resulted in discolouration, there is no direct evidence of degradation.

Thermal instability is not predicted, but as with many organic solids, a reliable boiling temperature is not possible to obtain
