Reference
Melting point / melting range // boiling point / boiling range: Differential scanning calorimetry
The first DSC measurement in an aluminium crucible with a hole showed an endothermal effect in the temperature range of 70 – 160 °C. A 2nd measurement was conducted being stopped at 180 °C. It showed an endothermal effect within the temperature range 90 – 140 °C. After both measurements visual inspection showed that the test item was unchanged. The results of the DSC measurement are summarized in Table1.
