Principle of Boiling point test |
A sample is heated gradually in a tube which is immersed in a liquid bath.The sample tube is held in close contact with a thermometer and it contains a boiling capillary which is fused about1 cm above its lower end. Upon approach of the boiling temperature bubbles emerge rapidly from the lower open end of the capillary. The boiling temperature is that temperature at which, on momentary cooling, the string of bubbles stops and liquid suddenly rises in the capillary. |

Description of key information
The boiling point of test chemical was determined to be greater than 300 °C at 976.3 hPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 300 °C
Additional information
The boiling point determination of test item was done as per the test guideline OECD 103. The method followed was according to Siwoloboff. The boiling point was observed to be greater than 300 °C at 976.3 hPa.
Other supporting data from another experimental report, also supported the selected key and exhibited the boiling point of test chemical by the distillation method as 370 deg C at the atmospheric pressure of 760 hPa. No decomposition of test chemical was observed at the boiling point.
