Melting and Boiling Point (DSC and Measurement in Test Glass)

In both DSC runs endothermic effects were observed in the temperature ranges from -40 °C through -20 °C, from 180 °C through 270 °C and from 460 °C through 590 °C. A mass loss of ~85 % was observed.

Results of the DSC-measurements

No.	Sample weight [mg]	Onset of Effect [°C]	Range of effect [°C]	Weight loss	Atmospheric pressure [hPa]
PN15517	21.43	-37.31 217.98 527.37	-40 – -20 (endo) 180 – 260 (endo) 470 – 590 (endo)	18.46 mg 86 %	1012.1
PN15531	8.57	-72.62 212.89 500.28	-40 – 20 (endo) 180 – 270 (endo) 460 – 580 (endo)	7.30 mg 85 %	1002.1

It is not possible to assign any of the observed endothermic effects definitely to melting or boiling of the test item.

For verification of the DSC resultsthe test item was additionally tested in a test glass. At approx. -10 °C the test item started to liquefy. At approx. 100 °C small bubbles started to form and to rise in the test glass. Then the test was aborted.

Note that the results of the DSC measurements and of the measurements in the test glass are not in accordance with each other.

Conclusions:

Melting and Boiling Point:
In the differential scanning calorimetry measurements according to Regulation EC No. 440/2008 Method A.1./A.2. and OECD Test Guidelines 102/103 (1995) at atmospheric pressure (991 hPa) endothermic effects were observed in the temperature ranges from -40 °C through -20 °C, from 180 °C through 270 °C and from 460 °C through 580 °C. A mass loss of ~85 % was observed.
The visual observation of the test item being heated in a test glass gave that the test item starts to liquefy at approx. -10 °C and that small bubbles started to form and to rise in the test glass at approx. 100 °C.
Based on the results and observations, it may be assumed that the test item liquefies between -40 and -10 °C and decomposes while boiling at temperatures ≥ 100 °C.

Description of key information

The test item decomposes while boiling at temperatures ≥ 100 °C.
