Results and discussion

Boiling point
Boiling pt.:
395 °C
Atm. press.:
ca. 1 atm
Decomposition:
ambiguous
Remarks on result:
other: Slow endothermic departure showing the beginning of the boiling transition with a probable overlay of an oxidative decomposition (exothermic departure)

Melting range: 182 - 185°C

Applicant's summary and conclusion

Conclusions:
A-164220.0 shows a broad boiling range from 300°C with a likely oxidative decomposition; therefore, it does not show a clear boiling temperature.
