Reference
Two DSC measurements in aluminium crucibles with a hole showed an endothermal effect after the melting in the temperature range of 240 - 340 °C. The onset was ambiguous due to the atypical course of the measurement for a boiling. Directly afterwards and exothermal effect was observed.
The results of the DSC measurements are summarised in Table 1.

An additional measurement with the capillary method was performed in order to clarify the boiling range. Since this measurement was performed only as a verifying screening a high heating rate of 10 K/min was chosen and therefore the absolute temperature values derived with the capillary method are not as accurate as the DSC results. The filling height of the test item was approx. 5 mm. The results are summarised in Table 2.
