- Version / remarks:
- 1998
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- <= -100 °C
- Atm. press.:
- >= 998 - <= 1 000 hPa
- Conclusions:
- The test item has no melting point down to a temperature of -100 °C.
- Executive summary:
The study was determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1., OECD Test Guideline 102 (1995) and GLP.
At ambient conditions, the test item is a liquid. Therefore the crucibles were cooled down from ambient temperature to -100 °C with a constant cooling rate of 0.25 K/min under an inert atmosphere.
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 item has no melting or freezing point down to a temperature of -100 °C (998 or 1000 hPa, respectively).
Reference
Description of key information

Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -100 °C
Additional information
The test item has no melting point down to -100 °C at atmospheric pressure (998 or 1000 hPa, respectively) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).
