Results and discussion
Boiling point
- Boiling pt.:
- > 333.5 °C
- Atm. press.:
- 101.3 kPa
Applicant's summary and conclusion
- Conclusions:
- > 333.5 C @ 101.3 kPa
- Executive summary:
The boiling point determination was undertaken with reference to OECD Guideline 103 using the Siwoloboff method.
It was determined that the boiling point for Compound 202723 was >543.15K. No change in physical state or appearance of the test material was noted at this temperature.
It is noted that the determined melting point for this material was recorded as 603.15K to 607.15K.The OECD Gudielines suggest that the maximum temperature achievable with the Siwoloboff technique is 573.15K.Therefore following the preliminary investigation the experiment was terminated and the boiling point recorded as greater than the highest temperature achieved during the preliminary investigation.
