Any other information on results incl. tables
Closed cup: The measurements showed an endothermic effect in the temperature range 260 - 270°C directly followed by a spontaneous exothermal decomposition in the temperature ranges 270 - 290°C with a decomposition energy of -170 J/g followed by a second exothermal decomposition in the temperature ranges 290 - 450°C with a decomposition energy of -300 J/g.
Open cup: A measurement showed an oxidation reaction starting at approximately 240°C. This oxidation reaction covers the thermal decomposition.
