Any other information on results incl. tables

First test results

The heat flow record showed an endothermic effect between 270 °C and 429 °C, with peak at 359 °C and onset at 349 °C. The boiling point is 349 °C.

 

Second test results

The heat flow record showed an endothermic effect between 270 °C and 414 °C, with peak at 353 °C and onset at 352 °C. The boiling point is 352 °C.

 

Conclusion

The boiling temperature of the sample is 350 °C (the mean of two measurements).
