Remarks:
The study was conducted under supervision of a quality assurance unit which had ensured e.g instrumentation validation, reagent/materials certification, analyst certification and providing standard operating procedures.
Type of method:
photocell detection
Key result
Boiling pt.:
233.5 °C
Atm. press.:
101.3 kPa
Decomposition:
no
Conclusions:
The boiling point of the test substance was determined to be 233.5 °C at 1013 hPa.
Executive summary:

A study was conducted according to OECD test guideline 103 to determine the boiling point of the test item using photocell detection. The test liquid was filled into a dry, clean boiling point sample tube up to a height of 15 - 18 mm. The heating rate was 1 °C/min, for precision measurements 0.2 and for exploratory measurements 5 °C/min. The start temperature was approx. 5 min below the expected boiling point. The stop temperature was 10 °C above the expected boiling point for detailed measuring curves or maximal temperature of the measuring cell for automatic stop. The waiting time was 2 min. The boiling point of the test substance was determined to be 233.5 °C at 1013 hPa.

Description of key information

The boiling point of the test substance was determined to be 233.5 °C at 1013 hPa.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
233.5 °C
