The test item at 39 deg c, but no string of bubbles were observed up to 300,

inferring B.P. to be greater than 300 deg C.

Method according to Siwoloboff

 

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 Tetraethylammonium chloride is greater than 300°C at 966.4 hPa.
Executive summary:

The boiling point determination of Tetraethylammonium chloride (CAS No. 56-34-8) was done following OECD Guideline 103 and according to the method of Siwoloboff. The test item at 39 deg c, but no string of bubbles were observed up to 300, inferring B.P. to be

greater than 300 deg C and boiling point was considered to be greater than 300°C at 966.4 hPa.

Description of key information

The boiling point determination of Tetraethylammonium chloride is greater than 300°C at 966.4 hPa.

Key value for chemical safety assessment
