Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
not specified
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:
Analysis was performed using the thermogravimetric analysis method under a nitrogen atmosphere using platinum sample pans. The pan was cleaned and tared and the test sample was added. The sample was heated from ambient temperature to 800°C at a rate of 20°C/min and the mass loss was recorded.

GLP compliance:
not specified
Type of method:
other: Thermogravimetric Analysis
Key result
Atm. press.:
101.3 kPa
Decomposition:
yes
Decomp. temp.:
ca. 264 °C
Remarks on result:
not determinable

Onset of the primary mass loss (degradation/evaporation) was extrapolated to be 264°C.

Conclusions:
Under the study conditions, the boiling point of the test substance could not be determined due to degradation/evaporation commencing at 264°C.
Executive summary:

A study was conducted to determine the boiling point of the test substance using the thermogravimetric analysis method. The analysis was performed under a nitrogen atmosphere using platinum sample pans. The pan was cleaned and tared and 14.992 mg of sample was added. The sample was heated from ambient temperature to 800°C at a rate of 20°C/min and the mass loss was recorded. Onset of the primary mass loss (degradation/evaporation) was extrapolated to be 264°C. Under the study conditions, the boiling point of the test substance could not be determined due to degradation/evaporation commencing at 264°C (ADM, 2019).

Description of key information

The boiling point of the test substance was determined using the thermogravimetric analysis method (ADM, 2019).

Key value for chemical safety assessment

Additional information

Boiling point could not be determined due to degradation/evaporation at 264°C.
