Key result
Melting / freezing pt.:
< -100 °C
Atm. press.:
> 1 006 - < 1 008 hPa

Results

During the cooling phase in the temperature range of 25 °C to -100 °C, no thermal effects were observed which can be associated with the overcooling of the test item.

During the heating phase no endothermic effect (melting) until an exothermic effect in the temperature range of 100 – 180 °C was observed.

 

Final Results

The test item has no melting point down to a temperature of -100 °C at atmospheric pressure (1006 - 1008 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).

Conclusions:
A melting point value of <-100 °C (at 1006 - 1008 hPa) was determined for the test substance according to E.U. Method A.1.

Description of key information

Melting point: <-100 °C at 1006 - 1008 hPa (EU Method A.1., differential scanning calorimetry)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-100 °C
