Type of information:

experimental study

Adequacy of study:

key study

Study period:

05/12/2014

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: GLP accredited laboratory

Qualifier:

according to guideline

Guideline:

EU Method A.2 (Boiling Temperature)

Deviations:

no

GLP compliance:

yes

Type of method:

method according to Siwoloboff

Decomposition:

yes

Decomp. temp.:

242 °C

Remarks on result:

other: Tiny bubbles were observed from 184°C and the sample was found to have changed colour to light brown at 242°C. Therefore the sample was suspected to have undergone thermal decomposition and the testing was stopped.

Conclusions:

Boiling temperature not determined. Decomposition at 242°C.
