- Melting / freezing pt.:
- ca. -41 - ca. 18 °C
- Remarks on result:
- other: The cooling run shows a crystallisation at 13 °C.
- Conclusions:
- Under the study conditions, the test substance showed an area of melting temperatures between -41 and 18 °C (melting of crystalline parts).
- Executive summary:
The melting temperature of the test substance was determined in accordance with the OECD Guideline 102 and EU Method A.1.
The practical test was performed based on the in-house test procedure VTA(S) 31X93001.02: "Melting temperature determination (Tm) of solid and liquid substances by means of DSC.
Under the study conditions, the test substance showed an area of melting temperatures between -41 and 18 °C (melting of crystalline parts). Furthermore, there was a glass transition temperature (amorphous components) at -51°C. The cooling run showed a crystallisation at 13 °C (Kintrup, 2010).
Reference
The test material shows a glass transition temperature (amorphous components) at -51°C.
The cooling run shows a crystallisation at 13 °C.
Description of key information
The melting point was determined according to OECD Guideline 102 and EU Method A.1 (Kintrup 2010a).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 18 °C
Additional information
The melting point was between -41 and 18°C.
