The measurement in an aluminium crucible with a hole showed no endothermic effect after melting only decomposition starts at a temperature of approximately 260 °C.
An exothermal decomposition starts in the glass crucible at a temperature of 245 °C and a visual inspection after the measurement showed a black coloration of the test item. The test item had no boiling point; the test item decomposes first at a temperature of 245 °C.
The measurement in an aluminium crucible with a hole showed an endothermic effect in the temperature range 320 - 380 °C and 310 - 380 °C respectively with an onset temperature of 365 °C or 356 °C.

An exothermal decomposition starts in the glass crucible at a temperature of 260 °C and an optical inspection after the measurement showed a discoloration of the test item to black.
The test item boiled under decomposition in the temperature range 356 - 365 °C at atmospheric pressure (1013.3 hPa).
The test item has no boiling point at atmospheric pressure. It decomposes first.
The measurement in the aluminium crucibles with a small hole showed an endothermic effect (melting) in the temperature range 40 - 65 °C and an exothermal decomposition in the temperature range 260 - 350 °C. The DSC-measurement showed no endothermic effect between the melting point at approximately 50 °C and the decomposition of the test item beginning at 260 °C.
Two measurements in closed glass crucibles showed an endothermic effect (melting) in the temperature range 40 -70 °C and an exothermal decomposition in the temperature range 245 -450 °C with a decomposition energy of 649 and 871 J/g, respectively.
Description of key information
The test item boiled under decomposition in the temperature range 356 - 365 °at atmospheric pressure (1013.3 hPa). An exothermal decomposition starts in the glass crucible at a temperature range of 245 - 260 °C.
