Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- other: OECD 102 (DTA/DSC)
- Qualifier:
- according to guideline
- Guideline:
- other: OECD 113 (DTA/DSC)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Decomposition:
- yes
- Remarks:
- The unsteady base line and inconstant thermal (approx. 230 °C and 450 °C) effects could be interpreted as decomposition (> 230 °C) of the test item.
- Decomp. temp.:
- > 230 °C
- Remarks on result:
- other: could be interpreted as decomposition
- Conclusions:
- Since no steep endothermic signal could be detected for HPP 12879-1 there is no indication for a definite boiling point. The unsteady base line and inconstant thermal (approx. 230 °C and 450 °C) effects could be interpreted as decomposition (> 230 °C) of HPP 12879-1.
- Executive summary:
A Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC) was used to determine the boiling point of HPP 12879 -1. Between approx. 230 °C and 320 °C and approx. 330 °C and 450 °C endothermic effects were observed. Since no steep endothermic signal could be detected there is no indication for a definite boiling point. The unsteady base line and inconstant thermal (approx. 230 °C and 450 °C) effects could be interpreted as decomposition (> 230 °C) of HPP 12879 -1.
Reference
Between approx. 230 °C and 320 °C and approx. 330 °C and 450 °C further endothermic effects were observed. Since no steep endothermic signal could be detected there is no indication for a definite boiling point. The unsteady base line and inconstant thermal effects could be interpreted as decomposition of the test item.
Description of key information
Since no steep endothermic signal could be detected for HPP 12879-1 there is no indication for a definite boiling point. The unsteady base line and inconstant thermal (approx. 230 °C and 450 °C) effects could be interpreted as decomposition (> 230 °C) of HPP 12879-1.

Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
