- Conclusions:
- The boiling point was determined to be 308.5 ± 0.4 °C (mean value of main studies).
- Executive summary:
A study according to OECD TG 103 was performed.
In the main study, a small amount of test item was filled into two small glass tubes and boiling capillaries were inserted.
The test item was heated from 250 up to 400 °C, with heating rate of 3 K/min.The samples were observed visually through a lens. A current stream of bubbles from the capillary indicates the boiling.
Two separate measurements were done. In the first run, the boiling of the substance was observed at 308.2 °C, while in the second run substance boiled at 308.7 °C.
Therefore, boiling point point was determined to be 308.5 ± 0.4 °C (mean value).
Reference
The table with detailed results is attached as illustration
Preliminary test (thermal analysis)
The melting of the substance was observed at 77.4 °C. After the experiment, the sample has lost about 97% of its mass and the color of the sample residue was changed to brown.
Main test (capillary method)
A total of four samples were used, two for each experiment. Samples in the same experiment gave the same exact result.
During both experiments the color of the samples changed from colorless to yellow before boiling and then to orange-red after boiling. This change could be due to decomposition of the test item.
Boiling point of the substance was determined as mean value of main studies results.
Description of key information
In a study according to OECD TG 103, the boiling point was determined to be 308.5 ± 0.4 °C.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 308.5 °C
