Results
Preliminary test
From 375°C upwards the weight of the sample decreased significantly. At 428°C the sample weight had decreased by 25%.
After the experiment a small brown residue remained in the sample container.
Main study
During cooling as well as during heating, no effects were observed which were caused by crystallisation and/or melting. Between 350°C and 475°C an endothermic peak was observed which was due to boiling of the test substance. The extrapolated onset was determined to be 417.15°C.
During the second experiment the endothermic boiling peak was observed with an extrapolated onset of 417.44°C.
Additionally, the test substance was stored
overnight in a -20°C freezer in order to determine if crystallization
occurs. After storage the test substance had not been crystallized. From
this it was concluded that the melting temperature is < -20°C
(253K).
Description of key information
Key value determined using OECD guideline 102 and EU test standard A1.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
