Justification for type of information:

Experimental result performed using standard methods of analysis.

Qualifier:

according to guideline

Guideline:

OECD Guideline 103 (Boiling point/boiling range)

Principles of method if other than guideline:

The boiling point of a liquid is the temperature at which that liquid is converted to a gaseous state. It can be defined as the temperature at which the vapour pressure of the liquid becomes equal to the pressure at the surface of the liquid.

TEST DESCRIPTION AND RESULT

Method Details	Observations	Remarks if, any
Guideline	OECD 103		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	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.
Quantity of chemical used	g/ml	1 g
Nature of the Bath taken	·         Oil bath ·	OIL
	If oil bath is used, specify ·         ·	SILICONE
Atmospheric pressure	hPa	966.4
Boiling point (°C) (RESULT)	°C	greater than 300

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.
