Main Test Siwoloboff Method

The observations are stated in the following table:

 

Observations	Temperature First determination	Temperature Second determination
The test item was a clear light yellowliquid with colourless condensate	132°C (405.2 K)	133°C (406.2 K)
Colour slightly darker	Since 200°C (473.2 K)	Since 200°C (473.2 K)
Individual bubble , the colour gettingdarker	Since 300°C (573.2 K)	Since 240°C (513.2 K)
Boiling at the surface was observed,no bubble chain developed	-	Since 340°C (613.2 K)
Vapour expansion with more bub­bles, boiling at the surface was ob-served, no bubble chain developed	350°C (623.2 K)	-
Colour very dark, burner switched off	400°C (673.2 K)	400°C (673.2 K)
No more bubbles visible	290°C (563.2 K)	312.4°C (585.6 K)
After cooling down the test item was very viscous, clear brown liquid, the test item decom­posed.

Conclusions:

Under study conditions, no boiling point could be determined because the test substance decomposes before its boiling point at > 200°C.

Executive summary:

A study was conducted to determine the boiling point of the test substance, using siwoloboff method according to OECD Guideline 103 and EU Method A.2. The test substance had changed its colour and consistence to a very viscous clear brown liquid during the tests and after cooling down. Therefore, the beginning of decomposition should be stated as 200°C (473.2 K). These values were the results of two independent determinations. As the test substance decomposed, a correction to standard pressure following Sidney-Young was not applied. No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study was considered valid. Under study conditions, no boiling point could be determined because the test substance decomposes before its boiling point at >200°C (Muckle, 2017).

Description of key information

The boiling point of the test substance was determined using The Siwoloboff method according to OECD Guideline 103 and EU Method A.2 (Muckle, 2017).

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

200 °C

Additional information

The test substance decomposes before its boiling point at >200°C.
