- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Atm. press.:
- >= 995 - <= 1 005 hPa
- Remarks on result:
- other: No melting point in the temperature range from -100 to 250 °C
- Conclusions:
- Under the conditions of this study, the test material has no melting point in the temperature range from -100 to 250 °C at atmospheric pressure (995 – 1005 hPa).
- Executive summary:
The melting point of the test material was investigated in accordance with the standardised guidelines OECD 102, EU Method A.1 and OCSPP 830.7200, under GLP conditions using differential scanning calorimetry.
In the temperature range of -100 – approx. 250 °C, no endothermic effect (melting or boiling) was observed. An exothermic effect was observed in the temperature range of approx. 250 – 350 °C (decomposition of the test material). During the cooling and the subsequent heating phase, no thermal effects were observed in the temperature range from -100 to 25 °C.
Under the conditions of this study, the test material has no melting point in the temperature range from -100 to 250 °C at atmospheric pressure (995 – 1005 hPa).
Reference
- In the temperature range of -100 – approx. 250 °C, no endothermic effect (melting or boiling) was observed. An exothermic effect was observed in the temperature range of approx. 250 – 350 °C (decomposition of the test material).
- During the cooling and the subsequent heating phase, no thermal effects were observed in the temperature range from -100 to 25 °C. It can be assumed that the test material has no melting or freezing point in this temperature range, i.e. the test material has no melting point down to a temperature of -100 °C.
Description of key information
Under the conditions of this study, the test material has no melting point in the temperature range from -100 to 250 °C at atmospheric pressure (995 – 1005 hPa).
Key value for chemical safety assessment
Additional information
The melting point of the test material was investigated in accordance with the standardised guidelines OECD 102, EU Method A.1 and OCSPP 830.7200, under GLP conditions using differential scanning calorimetry. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
In the temperature range of -100 – approx. 250 °C, no endothermic effect (melting or boiling) was observed. An exothermic effect was observed in the temperature range of approx. 250 – 350 °C (decomposition of the test material). During the cooling and the subsequent heating phase, no thermal effects were observed in the temperature range from -100 to 25 °C.
Under the conditions of this study, the test material has no melting point in the temperature range from -100 to 250 °C at atmospheric pressure (995 – 1005 hPa).
