Principle of Boiling point test

A sample is heated gradually in a tube which is immersed ina liquid bath. The sample tube is held in close contact with athermometer and it contains a boiling capillary which is fused about1 cm above its lower end. Upon approach of the boilingtemperature bubbles emerge rapidly from the lower open end of thecapillary. The boiling temperature is that temperature at which, onmomentary cooling, the string of bubbles stops and liquid suddenlyrises in the capillary.

Executive summary:

The boiling point determination of test chemical was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was observed to be 238 °C at 978.1hPa.

Description of key information

The boiling point determination of test chemical was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was observed to be 238 °C at 978.1hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
238 °C

Additional information

The boiling point determination of test chemical was done following OECD Guideline 103 and according to the method of Siwoloboff. The test was conducted in replicates and mean boiling point was observed to be 238 °C at 978.1hPa.

 

Based on the data obtained from the various reliable sources, the boiling point of test chemical was determined to be at 239°C.

Based on the data obtained from the various reliable sources, the boiling point of test chemical was determined to be at 240 ° C.

 

Thus, on the basis of above all sources, it was observed that the boiling point of test chemical ranges from 238 °C to 240 ° C.
