Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Qualifier:
according to
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.2 (Boiling Temperature)
Deviations:
no
GLP compliance:
no
Type of method:
method according to Siwoloboff
Atm. press.:
ca. 1 Bar
Decomposition:
yes
Decomp. temp.:
ca. 198 °C

 Temperature in °C  Observations
 85 - 86  Start of melting
 96 - 97  Completely melted to a clear liquid
 198- 199  Colour change from white to yellow
 250 Test terminated.  No constant bubble chain could be observed. Colour: red
Conclusions:
Decomposition >=198 °C
Executive summary:

No boiling point could be detrmined becaus of decomposition of the testsubstance beginning at ca. 198 °C.

Description of key information

Decomposition at ca. 198 °C

Key value for chemical safety assessment

Additional information

No boiling point could be determined because of decomposition of the test substance beginning at approx.198°C.
