Atm. press.:
ca. 1 013 hPa
Decomposition:
yes
Decomp. temp.:
>= 225 °C

Two DSC measurements in aluminium crucibles with a hole showed a multistage endothermal effect after the melting in the temperature range of 225 - 295 °C with onset temperatures of 242.81 °C and 239.69 °C, respectively. No further endothermal or exothermal effects were observed up to the final temperature (500 °C). The mass loss after the DSC measurements amounted to approximately 88 %.

Due to the optical inspection after the measurement and the mass loss of 88 % it was concluded that the test item boiled under decomposition starting at 225 °C.
