Results and discussion

Boiling point

Key result

Decomposition:

yes

Remarks:

The boiling point of the test item Allyltributylphosphonium chloride ist technically not feasible as the test item decomposed before boiling

Decomp. temp.:

ca. 300 °C

Remarks on result:

not determinable

Any other information on results incl. tables

Observations	Temperatures
The test item began to melt	85 °C
The test item completely melted to a slightly yellowish clear liquid	105 °C
Individual bubble with long interval, the colour getting slightly greenish	Since 300 °C
Often bubbles were visible	Since 300 °C
The test item boiled with lots of bubbles but not developed bubble chain	333 °C
Performing of heating	Up to 338 °C
No more bubbles were observed	290 °C

After cooling down the test item stayed as a clear greenish gel like mass, decomposition was considered

Applicant's summary and conclusion

Conclusions:

The melted test item test was filled into a sample tube containing a capillary tube in such
a manner that the sealed part of the capillary was lying below the surface of the test item.
When the test item was solid again the sample tube was then set into the aluminium
block. The block was heated with a quick heating rate. Heating was performed with a gas
burner. All observations were documented.
As signs of decomposition were observed, the sponsor was contacted to discuss, if
the melting/boiling point should be determined and what the final temperature
should be if DSC is applied.
After consulting with the sponsor the DSC measurement should have been performed up
to 345 °C.
