- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7200 (Melting Point / Melting Range)
- Version / remarks:
- 1998
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Remarks:
- A small amount of the test item was also tested on basis of capillary method
- Key result
- Melting / freezing pt.:
- > 500 °C
- Atm. press.:
- 1 001 hPa
- Decomposition:
- no
- Remarks on result:
- not determinable
- Conclusions:
- The test item has no melting point up to 500°C at atmospheric pressure (1001 hPa).
- Executive summary:
The melting point of the test item was investigated by differential scanning calorimetry and the capillary method according to OECD guideline 102 and EU Method A.1. The test item has no melting point up to 500°C at atmospheric pressure (1001 hPa).
Reference
To verify the results of the DSC measurements, an additional measurement with the capillary method in triplicate was performed in the temperature range from room temperature to 400°C with a heating rate of 10 K/min. Up to a temperature of 400°C no melting of the test item could be observed. During heating up the test item to 400°C, no discolouration was detected. Combining the results of the DSC measurement and the capillary method, no melting of the test item could be observed up to the maximum measurement temperature of 500°C. The two endothermic effects observed in the DSC method can be explained by the loss of water (temperature range 50-120°C) and chemical bonded water (temperature range 260-410°C).
Description of key information
The melting point of the test item was investigated by differential scanning calorimetry and the capillary method according to OECD guideline 102 and EU Method A.1. The test item has no melting point up to 500°C at atmospheric pressure (1001 hPa).
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.
