Principle of Boiling point test

The boiling point of a liquid is the temperature at which that liquid is converted to a gaseous state. It can be defined as the temperature at which the vapour pressure of the liquid becomes equal to the pressure at the surface of the liquid.

Conclusions:
The boiling point of test chemical is greater than 213.3 °C at 972.4 hPa.
Executive summary:

The boiling point determination of test chemical was done as per the test guideline OECD 103. The method followed was according to Siwoloboff. The boiling point of test chemical is 213.3°C at 972.4 hPa.

Description of key information

In an experiment,the boiling point determination of test item was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was determined to be 213.3°C at 972.4 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
213.3 °C

Additional information

In an experiment,the boiling point determination of test item was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was determined to be 213.3°C at 972.4 hPa.

Other supporting study from authoritative database indictes that the boiling  point of test chemical was determined to be in the range of 107-108 deg C at 22 to 26 mm Hg and 112 degree celcius at 20 mm Hg.

As the data from experiment has K1 reliability and the test was performed using OECD guidelines which has the value of boiling point temperature as 213.3 degree C thus considered as key study for the chemical safety assessment.
