Qualifier:
according to
Guideline:
EU Method A.2 (Boiling Temperature)
Deviations:
no
GLP compliance:
yes

method according to Siwoloboff
Specific details on test material used for the study:
Component of a Polyurethane System

Key result
Decomposition:
yes
Remarks:
(discolouration of test material)
Decomp. temp.:
236 °C

The sample started to discolour at 235°C (run 1) and 236°C (run 2), therefore the test was terminated and the boiling point could not be determined.

Conclusions:
The decomposition temperature of the substance was estimated to be 236 °C and the boiling point could therefore not be determined.

Description of key information

The decomposition temperature of the test substance was determined to be 236°C, following EU test method A.2, using the Siwoloboff method (Baker, 2010)

Key value for chemical safety assessment

Additional information

The sample started to discolour at 235°C (run 1) and 236°C (run 2), therefore the test was terminated and no boiling point could be determined. The discolouration was considered as a sign of decomposition, therefore the decomposition temperature was concluded to be 236°C.
