Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:

- Adequacy of study:
- key study
- Study period:
- 2008-06-10 to 2008-12-02
- Reliability:
- 2 (reliable with restrictions)

- Remarks:
- Food and Consumer Product Safety Authority (VWA), Den Haag, The Netherlands
- Type of method:
- differential scanning calorimetry
- Decomposition:
- yes
- Decomp. temp.:
- > 75 °C
- Remarks on result:
- not measured/tested
- Remarks:
- reaction and/or decomposition of the test substance was observed > 75 °C
- Conclusions:
- The test item showed no boiling effects before decomposition (OECD Guideline 102, differential scanning calorimetry).
- Executive summary:
In a Kofler hot bar test (2013-0230-DKP), the test item showed no sign of melting until 72 °C (when the substance started to soften). The softening range (72-86 C°) and the melting range (86-92 °C) measured during the Kofler hot bar test are in line with the second endothermic effect observed during the DSC study. It is therefore concluded that the endothermic effect observed, during the DSC, starting at ca. 75 °C was the melting of the substance.
The same DSC study did not show any other endothermic effect until ca. 200 °C, where an exothermic effect was observed, as associated to reaction/decomposition of the test substance.
