Approximate accuracy of the instrument: ± 0.5 K (up to 600 K)
With method 1 (dynamic method) it was not possible to achieve a constant boiling temperature. When repeating the measurement the boiling temperature falls to finally 215°C. During this test the colour of the test substance changes from slightly yellow to yellow-brown.
Method 2: Capillary tube method
Visual observation:
- Begin of bubbling at about 208°C (1-2 bubbles / min)
- Constant bubbling at about 285°C (1 bubble / 5-1 0 s)
- Constant bubbling at about 292°C (1 bubble / 2-3 s)
- Instrument stops the measurement at 300°C (upper limit) without photocell detection
Atmospheric pressure: 96.9 kPa
Corrected temperature: 210 – 287°C (483 – 560 K) at 101.32 kPa
The temperatures were corrected to normal atmospheric pressure (101.32 kPa).
Method 3: DSC/TGA method
With exclusive application of the DSC method it was not possible to detect a boiling temperature (no endothermic peak). See enclosure 1 (attached DSC diagram).
The TGA-diagram shows a small loss of mass (ca. 3%) at about 210°C. At this temperature, a clear decline of the mass curve begins. This sharp decline had an onset temperature of about 269°C. At the end of the measurement (400°C) about 78 % of the test substance had evaporated. See enclosure 2 (attached TGA diagram).
Description of key information
Boiling temperature: The substance was observed to undergo thermal decomposition from about 210°C (EU Method A.2)
Key value for chemical safety assessment
Additional information
The boiling point of the substance has been determined using three different methods (Haas 2013); 1) dynamic method, 2) capillary tube method / photocell detection method and 3) Differential Scanning Calorimetry (DSC) combined with thermogravimetric analysis (TGA) method in accordance with EU Test Method A.2 and in compliance with a known quality system (ISO 9001:2008).
In the dynamic method, it was not possible to obtain a constant boiling temperature for the substance but a decomposition temperature of 216.7 - 274.9°C at 1013 hPa was obtained. During the study, a colour change from slight yellow to yellow-brown was observed. To further evaluate the boiling point of the substance accurately, a capillary tube/photocell detection method was used. The results of visual observation indicate an onset of boiling temperature from about 210 - 287°C. Also, in the DSC/TGA method, onset of decomposition temperature was observed at about 208°C with initial mass loss of about 3%. This was followed by sharp decline with an onset temperature of about 269°C. At the end of the study (400°C), about 78% of the test substance has been lost.
Based on the findings in the above studies, the submission substance is considered to undergoes thermal decomposition from about 210°C. The results are considered to be reliable and are used as weight of evidence.
In available secondary sources to which reliability could not be assigned, boiling point values of 237 - 247°C at 35 hPa and >250°C at 0.13 hPa, 236°C were reported for the substance.
