Results and discussion

Boiling point
Boiling pt.:
>= 158 °C
Atm. press.:
ca. 101 325 Pa
Decomposition:
yes
Remarks:
The test item is known to decompose before such a temperature and has therefore no experimental boiling point under atmospheric pressure.

Applicant's summary and conclusion

Conclusions:
The Clausius-Clapeyron equation determined in the vapor pressure study allows to extrapolate a boiling temperature of 158°C (ambient pressure of 101325 Pa).
