Reference
Preliminary test:
Three steps were registered with maxima at 120 °C, 270 °C resp. 470 °C. A total mass loss of 53.2 % at the final temperature could be observed (mass change in the range until 180 °C: 0.9 %; mass change in the range from 180 to 360 °C: 2.0 %, mass change in the range from 360 °C to 600 °C: 50.4 %;). No significant mass loss occurred due to purging.
Main test:
The DSC measurements were performed twice in the temperature range from 20 - 600 °C resp. from 20 - 350°C. A sharp endothermic peak indicating a melting point could be observed (peak maximum: 126 °C/126 °C; extrapolated onset temperature: 120.68 °C/ 120.27 °C; rounded mean of both determinations: 120 °C).
Upon further heating the DSC-curve showed two more peaks: one exothermic peak (peak maximum: 250 °C/ 251 °C) followed by an endothermic peak (peak maximum: 471 °C). The first one is probably due to exothermic decomposition after melting. The second one may be a result of a partial boiling of the decomposed test item. Due to the fact that the thermogravimetric measurement as well as the DSC-measurement did not show a complete mass loss in that temperature range, no normal boiling point could be observed.
