Results and discussion

Boiling point
Atm. press.:
1 008 mBar
Decomposition:
yes
Remarks on result:
other: The boiling temperature of Propazine was not determinable, as the test substance decomposed on melting.

Any other information on results incl. tables

It was noted during the melting point determination that the test substance formed a faintly yellow melt, indicating possible onset of decomposition. In the course of the boiling point determination (both in a preliminary test at 10ºC/minute, and a subsequent test at 1ºC/minute) the test substance continued to darken after melting. Additionally, in the test at 1ºC/minute, evolution of gas was noted from the sample at approximately 230ºC and this resulted in the sample being forced up the boiling tube at approximately 240ºC. These observations confirmed that the test substance decomposed on melting.

Applicant's summary and conclusion

Conclusions:
The boiling temperature of Propazine was not determinable, as the test substance decomposed on melting.
Executive summary:

The boiling temperature of Propazine was not determinable, as the test substance decomposed on melting.
