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 in replicates and mean boiling point was determined to be > 300°C at 96470 Pa.
Executive summary:

The boiling point of test chemical was determined. The study was performed in accordance with the OECD Guideline 103 (Boiling Point). The method followed was according to Siwoloboff. The test was conducted in replicates and mean boiling point was determined to be > 300°C  at 96470 Pa.

Description of key information

On the basis of available data from study report, the boiling point of test chemical was determined. The study was performed in accordance with the OECD Guideline 103 (Boiling Point). The method followed was according to Siwoloboff. The test was conducted in replicates and mean boiling point was determined to be > 300°C at 96470 Pa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
300 °C

Additional information

On the basis of available data from study report, the boiling point of test chemical was determined. The study was performed in accordance with the OECD Guideline 103 (Boiling Point). The method followed was according to Siwoloboff. The test was conducted in replicates and mean boiling point was determined to be > 300°C at 96470 Pa.

In a supporting study from handbook, the boiling point of test chemical was determined to be 327.88°C.

In an another study from modelling database, the boiling point of test chemical was predicted using the EPI Suite MPVPBP V1.43. The estimated boiling point of test chemical was evaluated to be 330.98˚C
