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.

Conclusions:
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 determined to be 121°C at 972.4 hPa.
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 determined  to be 121°C at 972.4 hPa.

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 determined  to be 121°C at 972.4 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
121 °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 determined  to be 121°C at 972.4 hPa.

Other supporting studies from various reliable sources such as authoritative databases and handbooks,the boiling point of test chemical was determined  to be in the range of 120 degree C to 121.6 degree C.

As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of boiling point temperature as 121 degree C at 972.4 hpa pressure,thus considered as key study for the chemical safety assessment
