- Remarks:
- the test item decomposes before the melting temperature is reached Because of the decomposition is observed, the boiling point determination is not possible.
- Key result
- Decomposition:
- yes
- Remarks:
- Signs of degradation of the substance were observed between 89.8°C (363.0 K) and 170.3°C (443.5 K)* (mean of two independent determinations). At the end of the test, the test item did not change back into the original state but remained caramelised.
- Decomp. temp.:
- >= 89.8 - <= 170.3 °C
- Remarks on result:
- not determinable
- Remarks:
- Decomposition
- Conclusions:
- No boiling point was recorded.
- Executive summary:
The boiling point of the test substance was not performed because of decomposition of the test substance.
According to the Main Test (see point 4.2), the degradation of the substance was observed between 90°C (363.2 K) and 170.7°C (443.7 K) (mean of two independent determinations) and no boiling point determination was carried out.
Reference
Pre-Test
First Pre-Test in a test tube
First a small amount was heated in a test tube in the aluminium block in order to approximate
temperature of melting and boiling of the test item or the degradation / decomposition
of the test item.
The following observations were done:
Table 4.2/1 Observations of the Pre-Test in a test tube
Observations |
Temperature* |
Colourless condensate visible |
103.3 °C |
Test item bloated appearance like beaten eggs white with a hard dome |
136.8 °C |
Colour change visible to yellow |
154.6 °C |
Test terminated, test item looks like cappuccino with milk froth |
188.2 °C |
*All temperatures were stated without the deviation of the thermometer. Under the dome the test item is liquid.
No melting / boiling point can be approximate with the first Pre-Test, performed in a test tube. However, signs of degradation of the test item were observed. The test item did not change back into the original state at the end of the first Pre-Test (irreversible change of appearance and colour).
Second Pre-Test in a capillary
The capillary tube containing the test item was set into the aluminium block with quick increase
in temperature ( < 10K/min) in order to better apprehend the melting range or the
degradation range of the test item.
The following observations were done:

*All temperatures were stated without the deviation of the thermometer
In the second Pre-Test performed in a capillary tube, no melting of the substance was observed, but signs of degradation of the substance were observed. At the end of this Pre- Test, the test item did not change back into the original state but remained caramelised.
Main Test
At first, the capillary tube containing the test item was set into the block at 85.1 °C. The block was heated gently. The test item shrivelled together at 89.4 °C the test was terminated because the performance criteria were not fulfilled (The test should be started at least 10 °C below the expected melting point). A second test was performed the capillary tube containing the test item was set into the block at 75.0 °C. The test item shrivelled together at 89.9 °C. At 130.4 °C the test item bloated and appeared as yellow. As the test item colour was slightly brown and the test sample expanded up in the capillary tube at 179.6 °C the test was stopped. Unfortunately the start of the colour change was missed therefore this test was not guilty. Therefore both tests were repeated.
The capillary tube containing a fresh test item sample was then set into the aluminium block at 75.0 °C (third determination) and at 75.1 °C (fourth determination). The block was heated gently at a temperature gradient of </= 1 °C/min.
The following observations were recorded:

In the Main Test, no melting point and boiling point/range was detected. However, signs of degradation of the substance were observed between 90°C (363.2 K) and 170.5°C (443.7 K)* (mean of two independent determinations). At the end of the test, the test item did not change back into the original state but remained caramelised.
RESULTS AND VALIDITY
Result Test Item OF14 AT
In all performed determinations (Pre-Tests and Main Test), no melting point and boiling point/range were detected and signs of degradation of the substance were observed. In all determinations, the test item did not change back into the original state but remained caramelised. According to the Main Test, the degradation of the substance was observed between 90°C (363.2 K) and 170.5°C (443.7 K) (mean of two independent determinations).
Validity
No validity criteria could be considered as the test item decomposed.
Description of key information
No boiling point was recorded due to the decomposition of the test item before boiling.
Key value for chemical safety assessment
Additional information
A fully reliable experimental study was conducted according to a recognized EU/OECD method and under GLP to determine the Melting point and the boiling point of the test item (see endpoint 4.2). However, no boiling point was determined considering that signs of degradation of the substance were observed before boiling between 90°C (363.2K) and 170.5 °C (443.7K).
