Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
Experimental test result performed using standard OECD test guidelines
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Principles of method if other than guideline:
A sample is heated gradually in a tube which is immersed in a oil bath. A sample is heated gradually in a tube which is immersed ina liquid bath. The sample tube is held in close contact with athermometer and it contains a boiling capillary which is fused about1 cm above its lower end. Upon approach of the boilingtemperature bubbles emerge rapidly from the lower open end of thecapillary. The boiling temperature is that temperature at which, onmomentary cooling, the string of bubbles stops and liquid suddenlyrises in the capillary.

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 Nonan-2-one (CAS No.821-55-6) 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 198°C at 981.7 hPa.
Executive summary:

The boiling point determination ofNonan-2-one(CAS No.821-55-6)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 198°C at 981.7 hPa.

Description of key information

The boiling point determination of Nonan-2-one(CAS No.821-55-6)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 198°C at 981.7 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
198 °C

Additional information

The boiling point determination ofNonan-2-one(CAS No.821-55-6)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 198°C at 981.7 hPa.

Other supporting studies from various reliable sources such as handbook and authotative databases also suggests that the boiling point of chemical Nonan-2-one was reported to be in the range of 192 degree C to 196 degreeC.

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 198 degree C at 981.7 hPa, thus considered as key study for the chemical safety assessment.
