Key result
Boiling pt.:
290.1 °C
Atm. press.:
101.3 kPa
Decomposition:
no

Two individual measurements were done, both yielding boiling points of 290.1 °C.

Conclusions:
The boiling point of the test substance was 290.1 °C at standard atmospheric pressure.
Executive summary:

The boiling point of the test substance was determined in accordance with OECD TG 103 by using photocell detection according to Siwoloboff. The substance was transferred into a test tube and the formation of steam bubbles was induced by immersion of a boiling capillary. The sample was heated at a rate of 0.2 °C per minute in an immersion bath. The ascending bubbles reflect the light of the built-in light source and thus can be separately detected by the photo cell (Mettler Thermo System FP90 with measuring cell FP81). The bubbles escaping before the boiling point has been reached are clearly different from the gas bubbles which escape with continuously increasing frequency at the boiling temperature. The boiling point of the test substance was 290.1 °C at standard atmospheric pressure.
