Results and discussion

Boiling point
Key result
Decomposition:
yes
Remarks:
first possible decomposition or changing in chemical form 120 - 220 °C second and more significant possible decomposition or changing in chemical form at 230 °C
Decomp. temp.:
ca. 230 °C
Remarks on result:
not determinable

Applicant's summary and conclusion

Conclusions:
The sample does not present a define boiling point but two decomposition phenomena at 120 °C and 230 °C
Executive summary:

120 - 220 °C : exotherimic departure showing a first possible decomposition or changing in chemical form 
230 °C : exotherimic departure showing a second and more significant possible decomposition or changing in chemical form
