Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

other: Freezing Temperature Method
Key result
Melting / freezing pt.:
< -14.74 °C
Atm. press.:
978.1 hPa
Decomposition:
no
Sublimation:
no
Remarks on result:
other: Other details not available
Conclusions:
The Freezing point of test chemical was determined with Freezing Temperature Method and it was found to be less than -14.74 °C at 978.1 hPa.
Executive summary:

The Freezing point determination of test chemical was done using crushed Ice and salt . No freezing was observed up to -14.74°C. Hence, the freezing point was inferred to be less than -14.74 °C at 978.1 hPa.

Description of key information

The Freezing point of test chemical was determined with Freezing Temperature Method and it was determine to be less than -14.74 °C at 978.1 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-15.27 °C

Additional information

The Freezing point determination of test chemical was done using crushed Ice and salt . No freezing was observed up to -14.74°C. Hence, the freezing point was inferred to be less than -14.74 °C at 978.1 hPa. This freezing point value when converted at 101 325 Pa is equivalent to -15.27°C.

Based on available data,the Freezing point temperature of chemical was determined to be 18.5-19.5 degree C.
