Method Details	Observations	Remarks if, any
Guideline	OECD 103
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.

Description of key information

The boiling point determination of 1-(1-naphthyl)ethanone (CAS No. 941-98-0) 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 297.6°C at 979.6 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

297.6 °C

Additional information

The boiling point determination of 1-(1-naphthyl)ethanone (CAS No. 941-98-0) 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 297.6°C at 979.6 hPa.

Other supporting studies from various reliable sources such as handbooks and authoritative database also suggests that the boiling point of chemical 1-(1-naphthyl)ethanone was reported to be in the range of 297 degree C to 302 degree C.

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 297.6 degree C at 979.6 hPa, 164 degree C at 13 Torr, in the range between 75 -80 Deg C at 0.15 Torr, thus considered as key study.
