Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The melting point of this substance proved difficult to measure. Testing using an Automated Mettler Toledo MP70 Melting Point System gave inconsistent results with the values from the machine not matching with the visual process of melting. The machine did suggest that the melting point lay in the range 32 -78C. Measurements using the Siwiloboff method produced more consistent results but suggested that melting occurred over the range 32 -72C. There was also some evidence of decomposition (discoloration) occuring. Measurements using a differential scanning calorimeter suggested that there are two transitions of state occuring, one at 32C and a second at 73C, although the lower transition could not be reproduced consistently. It can be concluded that the substance will be a solid below 32C and will be a liquid above 78C but the phase state in between is unclear. For this reason, a single value for the melting point is not reported.

Key value for chemical safety assessment
