Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From June 14, 2017 to June 19, 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
equivalent or similar to
Guideline:
OECD Guideline 103 (Boiling Point)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.2 (Boiling Temperature)
Deviations:
no
GLP compliance:
yes
Type of method:
differential scanning calorimetry
Key result
Boiling pt.:
272 °C
Atm. press.:
1 016 mBar
Decomposition:
yes
Decomp. temp.:
272 °C

271 °C (from first measurement)

273 °C (from second measurement)

272 °C (from third measurement)

From 272 °C the test substance shows a boiling and/or thermal decomposition with evaporation of the decomposition components. The DSC measurements were confirmed by means of TGA measurements under the same measuring conditions.

Conclusions:
Under the study conditions, the test substance shows a boiling and/or thermal decomposition earliest at ca. 272 °C (at 1016 mbar).
Executive summary:

A study was conducted to determine the boiling point of the test substance by differential scanning calorimetry according to EU Method A.2. and method similar to OECD Guideline 103. Three measurements were taken at 271 °C, 273 °C and 272 °C. From 272 °C the test substance shows a boiling and/or thermal decomposition with evaporation of the decomposition components. The DSC measurements were confirmed by means of TGA measurements under the same measuring conditions. Under the study conditions, the test substance shows a boiling and/or thermal decomposition earliest at ca. 272 °C (at 1016 mbar) (Kintrup, 2017).

Description of key information

The boiling point was determined according to EU Method A.2. and a method similar to OECD Guideline 103 (Kintrup, 2017).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
