- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018-05-16 to 2018-08-23
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 1995
- Deviations:
- not specified
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 2008
- Deviations:
- not specified
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Remarks:
- and capillary method
- Decomposition:
- yes
- Decomp. temp.:
- >= 230 °C
- Conclusions:
- Combining the results of the DSC measurements and the capillary method, no melting point of the test item could be observed. The endothermic effect in the DSC can be assigned to evaporating components (e.g. water). The tets item started to decompose at approx. 230 °C.
- Executive summary:
The test item has no melting point up to the decomposition temperature of approx. 230 °C at atmospheric pressure (1004 hPa) as determined by differential scanning calorimetry and capillary method according to OECD guideline 102 and EU method A.1. Study was conducted in accordance to GLP-requirements.
Reference
The test item showed a broad endothermic effect in the temperature range of approx. 80 -250 °C, followed by two exothermic effects in the temperature ranges of approx. 250 - 330 °C and 330 - 420 °C, with a mean overall energy of -290 J/g.
Description of key information
The test item has no melting point up to the decomposition temperature of approx. 230 °C at atmospheric pressure (1004 hPa) as determined by differential scanning calorimetry and capillary method according to OECD guideline 102 and EU method A.1. Study was conducted in accordance to GLP-requirements.
Key value for chemical safety assessment
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.
