Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Pour point (DIN ISO 3016 / ASTM D 97): < -90°C (taken as melting/freezing point)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-90 °C

Additional information

The pour point was determined according to DIN ISO 3016 / ASTM D 97 test methods. While not being identical to the melting / freezing point, the pour point measured in this study is taken as the melting / freezing point, since it identifies the correct range for the melting / freezing point (-77 °C in other sources) and since this parameter is not critical (< 90 °C given as -90 °C for the key value).
