Reference
Melting point / melting range// boiling point / boiling range: DSC measurement
Two DSC measurements with a heating rate of 10 K/min showed no endothermal effect (melting or boiling) in the temperature range of 25 – 500 °C. Both DSC measurements showed an exothermal effect in the temperature range of 450 – 490 °C. The results of the DSC measurements are summarized inTable 1.
