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.

Additional information

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 was determined to be 146°C at 976.9 hPa

In support to the key study data from handbook and authoritative databases, the boiling point of test chemical was determined to be 145.7°C at 101325 Pa.

Additional data from handbook indicates the boiling point of test chemical as147.3°C .

Also , data from handbook and authoritative databases, depicts the boiling point of test chemical to be in the range of 143 to 145°C.

In an another supporting study from reliable handbook,authoritative and modelling databases, the boiling point of test chemical was determined to be 144°C.
