Guideline

OECD 103

 

no string of bubble were observed upto 300 deg C, inferring boiling point to be greated than 300 Deg C.

Method

Method according to Siwoloboff

 

Principle ofBoilingpointtest

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 about 1cm above its lower end. Upon approach of theboiling temperature bubbles emerge rapidly from the lower open end of the capillary. The boiling temperature isthattemperature at which, on momentary cooling, the string of bubbles stops and liquid suddenly rises in thecapillary.
