Part of sample started turning brown before melted. At 320ºC, bubbles were observed as if the sample was boiling, while more and more samples turns black. When the sample is boiling at 360ºC, all the sample turns to completely black liquid. This is probably due to that the decomposition happens while sample boils.

Conclusions:
Boilining point range from 366-377 °C, decomposion during boiling at approximately 360 °C.
