Key result
Decomposition:
yes
Remarks on result:
not determinable

The sample is a colorless liquid in the boiling point tube at room temperature. During the course of heating, sample decomposition was observed. Decomposition was indicated by a change in the sample color from colorless to an orange-yellow color. The onset of this slow, subtle color change was difficult to detect. Boiling of the sample did not occur. Figure 1 shows photographs of the boiling point tube before and after heating of the sample.

Conclusions:
The boiling point of the sample could not be determined due to sample decomposition.
Executive summary:

In accordance with EU A2 Regulation (EC) No 440/2008, Annex, Official Journal of the European Union L142/1, boiling point was measured by the Siwoloboff method in a heated metal block using photocell detection (OECD Guidelines for The Testing of Chemicals, 103, July 27 1995).

The boiling point of the sample could not be determined due to sample decomposition.
