Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Boiling point
Administrative data
Link to relevant study record(s)
- 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
- 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.
Reference
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.
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
