Any other information on results incl. tables

FIRST EXPERIMENT:

Up to about 150°C (423 K) no significant heat effects were observed. Above 150°C (423 K) an exotherrnic effect which increased with increasing temperature was observed. Above 270°C (543 K) the exothermic effect increased considerably. During the experiment the sample lost 2.85 mg (20%) of its mass. After the experiment the sample had a black colour. It is likely that the observed heat effect is caused by reaction or decomposition of the test substance.

SECOND EXPERIMENT (FIRST RUN):

No significant heat effects were observed. After this run the sample was not changed visually; the mass of the sample appeared to be increased with 0.06 mg (0.4%). It is not clear whether this is a measuring error or significant.

SECOND EXPERIMENT (SECOND RUN):

An exothermic heat effect started at about 150°C (423 K). During this run the sample lost 0.63 mg (4%) of its mass. After the run the colour of the sample was black.

SECOND EXPERIMENT (THIRD RUN):

An exothermic effect which increased with increasing temperature was observed. The sample lost 2.22 mg (13%) of its mass during this run. In total during the second experiment the sample lost 2.79 mg (17%) of its mass.

Applicant's summary and conclusion

Conclusions:
In conclusion, in an air atmosphere the test substance reacts or decomposes at temperatures above about 150°C (423 K).
Executive summary:

In a GLP compliant, guideline boiling point study in an air atmosphere the test substance reacts or decomposes at temperatures above about 150°C (423 K).
