Key result
Melting / freezing pt.:
<= -100 °C
Atm. press.:
>= 998 - <= 1 000 hPa
Conclusions:

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).

Description of key information

The test item has no melting point down to a temperature of -100 °C.

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).
