Principle of method

 

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 and the test item does not string of bubbles upto 300, inferring boiling point to be greater than 300 °C at 964.7 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 and the test item does not string of bubbles upto 300, inferring boiling point to be greater than 300 °C at 964.7 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 and the test item does not string of bubbles upto 300, inferring boiling point to be greater than 300 °C at 964.7 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
300 °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 and the test item does not string of bubbles upto 300, inferring boiling point to be greater than 300 °C at 964.7 hPa.

Other supporting studies from various reliable sources such as review article and authoritative database ,the boiling point of test chemical was determined to be in the range of 111 degree C at 189 degree C at 8 mm Hg to 21 mm Hg

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 >300 degree C thus considered as key study for the chemical safety assessment.
