Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP Guideline Study
Qualifier:
according to guideline
Guideline:
other: OECD 102 / OECD 113
Deviations:
no
Qualifier:
according to guideline
Guideline:
other: EU Method A.1 (Melting / Freezing Temperature)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Type of method:
other: Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC)
Boiling pt.:
220 - 290 °C
Atm. press.:
1 atm
Decomposition:
yes
Decomp. temp.:
140 - 215 °C
Remarks on result:
other: No pressure reported

From room temperature to 450 °C no definite boiling point could be observed. The inconstant endothermic effects between 220 °C and 290 °C could be interpreted as boiling range around 250 °C, very probably under degradation of the sample indicated by the unsteady base line.

Conclusions:
From room temperature up to 450 °C no definite boiling point could be observed. The inconstant endothermic effects between 220 °C and 290 °C could be interpreted as boiling range around 250 °C. After the heating process a brownish residue remained in the crucible which indicates decomposition.
Executive summary:

According to EU Method A. 1 no definite boiling point was detected. Between approx. 220 and approx. 290 °C a range of inconstant endothermic effects were detected. The inconstant endothermic effects could be interpreted as boiling range around 250 °C, very probably under degradation of the sample indicated by the unsteady base line. From approx. 330 °C up to approx. 450 °C a further exothermic effect was visible. After the heating process a brownish residue remained in the crucible which indicates decomposition of the test item.

Description of key information

Endothermic effects between 220 °C and 290 °C could be interpreted as a boiling range around 250 °C. 

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
250 °C

Additional information

From room temperature up to 450 °C no definite boiling point could be observed. The inconstant endothermic effects between 220 °C and 290 °C could be interpreted as boiling range around 250 °C. After the heating process a brownish residue remained in the crucible which indicates decomposition.
