Key result
Melting / freezing pt.:
< -60 °C
Atm. press.:
1 013 hPa

No melting point detected <-60°C.

Conclusions:
The melting point of the test substance is <-60°C.
Executive summary:

A study was conducted to determine the melting point of the test substance according to a method similar or equivalent to OECD Guideline 102 and EU Method A.1. Differential scanning calorimetry (DSC) was employed for this purpose. Duplicate specimens of the test substance were encapsulated in aluminium pans with pierced lids. It was subjected to a controlled temperature program of -60 to 500°C at 10K/min. No melting point was detected in this temperature range. Hence, the melting point of the test substance is <-60°C (Sohar, 2015).

Description of key information

The melting point was determined according to a method equivalent to OECD Guideline 102 (Sohar, 2015).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-60 °C

Additional information

The melting point was <-60°C.
