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.

Description of key information

The boiling point determination of test chemical was performed as per the test guideline OECD 103. The method followed was according to Siwoloboff. The boiling point was determined to be 168 °C at 968.5 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
168 °C

Additional information

The boiling point determination of test chemical was performed as per the test guideline OECD 103. The method followed was according toSiwoloboff. The boiling point was determined to be 168 °C at 968.5 hPa.

The other authoritative sources of information though indicate the boiling point to be in the range of 185 -190 degC.However for the purpose of the dossier as well as for the chemical safety report, the boiling point of the key study which is 168 degC shall be considered.
