Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling Point/Boiling Range)
Principles of method if other than guideline:
The boiling point of the substance could not be determinated by the Siwoloboff method, because the decomposition begins earlier than the boiling point. Therefore the boiling point of the substance was calculated from the thermogravimetric measurement ( Diffusion controlled evaporation)
GLP compliance:
no
Type of method:
other: thermogravimetry

The boiling point of the substance could not be determinated by the Siwoloboff method, because the

decomposition begins earlier than the boiling point. Therefore the boiling point of the substance was

calculated from the thermogravimetric measurement ( Diffusion controlled evaporation)

Applicant's summary and conclusion

Conclusions:
the boiling point of test substance was determined to be 142.9°C at 11Pa and extrapolated to be 367°C at 1013 hPa.
