Reference
Preliminary test
The preliminary testing showed an endotherm at approximately 107°C which was consistent with the melting temperature of the test item from the Certificate of Analysis. These preliminary tests were performed in manually pierced crucibles and therefore allowed
significant volatilization of the test item below its boiling point, causing a wide endotherm for the boiling temperature.
Definitive test
The definitive test was performed with a starting temperature above the melting temperature in laser perforated crucibles which allow for a degree of pressurization in the crucible, preventing premature volatilization of the test item. This gives a narrower endotherm and allows quantification of the boiling temperature.
Description of key information
The boiling point of the test item 2-ethylanthraquinone is 400 ± 1 °C at 101.0 kPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 400 °C
Additional information
The boiling point has been determined according to OECD TG 103 by differential scanning calorimetry to be 400 ± 1 °C at 101.0 kPa.
