Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
June 24, 2013
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Deviations:
no
Principles of method if other than guideline:
The substance has been tested according to SOP - STR 028
GLP compliance:
no
Type of method:
differential scanning calorimetry
Decomposition:
yes
Remarks on result:
other: The test item decomposes before melting or boiling.

A first endothermic peak, associated to solvent release, is observed between 25 and 170 °C. For the exothermic peak: Onset at 235.5 °C, Enthalpy = 12.7 J/g.

Conclusions:
The test item decomposes before melting or boiling.
Executive summary:

The substancehas been tested according to OECD 103.

The test item decomposes before melting or boiling.

Description of key information

 The test item decomposes before melting or boiling.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
846.88 °C

Additional information

The Boiling Point analysis was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis. The test item between 25 and 170 °C releases solvent as shown on first endothermic peak, followed by decompositionbefore melting or boiling.

An estimated value with Mpbpwin v.1.43* using the following smile has been reported to perform the risk assessment:
