Description of key information
The test substance has a melting point of 380 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 380 °C
Additional information
A literature review was conducted. In a weight of evidence approach these literature values were evaluated. The literature search resulted in four independent values. The melting point was determined to be between 380 and 400 °C (Hommel Handbook, query date 19 April 2016; Sax Handbook, 1992) and 380 °C at normal atmospheric pressure (CRC handbook, 2008). In addition the GSBL (Joint Substance Data Pool of the German Federal Government and the German Federal States) reported a melting point of 400 °C at normal atmospheric pressure. All 4 independent values are in the same range and therefore regarded as reliable. A melting point of 380 °C was chosen as key value.
