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

A study was performed to determine the boiling point of test chemical at atmospheric pressure.
The study was conducted in accordance with OECD 103, Guideline for testing of chemicals, for Boiling Point Adopted by Council on 27th July 1995.
The mean boiling point was determined to be 235.3 °C at 974.6 hPa.

based on the data available from other source ,the boiling point of the test chemical was determined to be 231.5 deg c. Also data from other handbooks , authoritatve database and secondary source indicates boiling point to be 231 deg c , 231 - 232 deg c ,231.5 - 232.5 deg c , all of which are supporting the key result .
