Results
An exothermic effect could be detected between 160 and 500 °C, with a decomposition energy of > -760 J/g, which is not completed at 500 °C.

No further endothermic effects were seen up to the decomposition of the test item starting at 160 °C, therefore the test item has no boiling point under normal pressure up to a temperature of 160 °C.
