Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
04.07.-16.08.2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
GLP compliance:
no
Type of method:
differential scanning calorimetry
Key result
Boiling pt.:
> 400 °C
Atm. press.:
1 013 hPa
Decomposition:
yes
Decomp. temp.:
260 °C

The test item started to decompose during melting. The decomposition products showed another endothermal effect starting at 440 °C. It can be assumed that this endothermal effect was caused by a boiling and further decomposition.

Conclusions:
The substance had no mean boiling point at atmospheric pressure (1013.3 hPa). The decomposition products showed a partial boiling starting at 440 °C.
Executive summary:

A study was conducted according to OECD test guideline 103 and Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry.  The test item and the reference are heated up from the starting temperature to the final temperature at a constant heating rate in a defined atmosphere (nitrogen). Open crucibles are used as containers for the test item and as empty reference crucible. The quantity of heat absorbed or released is measured and recorded. The substance had no mean boiling point at atmospheric pressure (1013.3 hPa). The decomposition products showed a partial boiling starting at 440 °C.
