1.1.1. Boiling point / boiling range:DSC measurement
One DSC measurement in an aluminium crucible with a hole showed an endothermal effect after the melting in the temperature range of 200 – 290 °C. The mass loss after the DSC measurements amounted to 92 %.
The resultsof the DSC measurementsare summarized inTable1.

Graphical presentations of the DSC runs are shown on page7(Figure1).
An additional measurement with the capillary method was performed in order to clarify the boiling range.
1.1.2. Boiling point / boiling range: capillary tube in a metal block
A measurement with the capillary method was performed to clarify the results of the DSC measurements. Since this measurement was performed only as a verifying screening a high heating rate of 10 K/min was chosen and therefore the absolute temperature values derived with the capillary method are not as accurate as the DSC results. The filling height of the test item was approximately 5 mm.
The results are summarized inTable2.

Approx. 180 °C: Test item appeared melted (clear, yellow) Approx. 200 °C: Beginning bubble formation, odour like hydrogen sulphide Approx. 210 °C: Increasing bubble formation Approx. 265 °C: Decreasing bubble formation, test item became darker Approx. 285 °C: Decreasing bubble formation, melt discoloured to amber Approx. 304 °C: Few bubbles, melt discoloured to brown Approx. 332 °C: Few bubbles, melt discoloured to dark brown Approx. 370 °C: No further bubble formation Approx. 285 °C: No further change |
Applicant's summary and conclusion
- Conclusions:
- Under consideration of the results from the DSC measurement and the capillary method it was concluded that the test item started to decompose before boiling could occur. Decomposition started at approx. 200 °C.
The test item had no boiling point at atmospheric conditions.
