Results - Boiling Point

The individual test results are shown as follows.

Number of Repetion	Results of observation
1	The test item was colorless and transparent at 45 °C. The color of the test item changed slightly from colorless to light yellow at 248°C, and then changed gradually to brown until the temperature of the test equipment reached 300°C. Although continuous bubbles were observed at 275 °C, this temperature was not judged a boiling point of the test item because the color of the test item had already changed.
2	The test item was colorless and transparent at 45 °C. The color of the test item changed slightly from colorless to light yellow at 254°C, and then changed gradually to brown until the temperature of the test equipment reached 300 °C. Although continuous bubbles were observed at 270 °C, this temperature was not judged a boiling point of the test item because the color of the test item had already changed.

Consequently, the boiling point of the test item was not observed because the test item changed (decomposed) at about 250 °C.

Description of key information

The boiling point of the test item was not observed because the test item changed (decomposed) at about 250 °C (OECD 103, observation).
