The results of the DSC measurement in an aluminium crucible(heat rate10 K/min) are summarized in the following table:

Temperature range [°C]	Onset [°C]	Peak max. [°C]	Enthalpy [J/g]	Remarks
175 – 197	183	186	107	Melting
280 – 325	not evaluable	320	84	Boiling
325 – 346	325	330	62	Decomposition

 

The DSC measurement detected a boiling point at 320°C followed by the decomposition starting at 325°C.

The results of the DSC measurements in a glass crucible(heat rate3 K/min) are summarized in the

following table:

 

Temperature range [°C]	Onset [°C]	Peak max. [°C]	Enthalpy [J/g]	Remarks
