Reference
In a pre-test (one run from 25 to 400 °C, rate 20 °C/min) two endothermic heat effects were observed, the first peak starting at 137 °C the second at 330 °C. After the experiment, the sample had lost about 95.8% of its mass and stained the cup black. In the main test an endothermic heat effect was observed at 136 °C. During these runs, samples lost no weight and a colorless stringy drop remained.
Description of key information
136 °C (OECD 102, A.1), 133 °C and 133-135 °C (DIN 53181)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 136 °C
