Two endothermic effects have been observed in the temperature range 25 °C to 120 °C. The first effect (onset temperature = 38 °C) was assigned to melting, the second (starting at ca. 75 °C) to decomposition because of the change in physical state and colour (from original brown to reddish/brown).
From approximately 200 °C, an exothermic effect was observed. This effect was assigned to reaction/decomposition of the test substance because of the change in physical state and colour (from original brown to reddisch/brown).
Softening range detected to: 72 - 86 °C
Description of key information
Melting range: 86 to 92 °C at approx. 1013 hPa (Kofler hot bar).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 86 °C
Additional information
In a Differential Scanning Calorimetry study, two endothermic effects have been observed in the temperature range 25 °C to 120 °C. The first effect (onset temperature = 38 °C) was assigned to melting, the second (starting at ca. 75 °C) to decomposition. The Kofler hot bar test showed no sign of melting until 72 °C (when the substance started to soften). The softening range (72-86 C°) and the melting range (86-92 °C) measured during the Kofler hot bar test are in line with the second endothermic effect observed during the DSC study. It is therefore concluded that the melting range of the substance is 86-92 °C.
