1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
Experimental result performed using standard methods of analysis
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Principles of method if other than guideline:
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.

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.
