Reference

Endpoint:

boiling point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

08 February 2018

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

OECD Guideline 103 (Boiling Point)

Qualifier:

according to guideline

Guideline:

EU Method A.2 (Boiling Temperature)

Qualifier:

equivalent or similar to guideline

Guideline:

EPA OPPTS 830.7220 (Boiling Point / Boiling Range)

Principles of method if other than guideline:

only a pre-test was performed, because the substance decomposed before boiling

GLP compliance:

yes (incl. QA statement)

Type of method:

other: capillary method

Decomposition:

yes

Decomp. temp.:

>= 100 °C

Remarks on result:

not determinable

The substance decomposed before boiling.

Temperature	Observation
Beginning at 100 °C	Condensate, colourless and partially pink discoloured from the test item, was observed. The test item slightly contracted
Beginning at 145 °C	Condensate dropped down to the surface of the test item.
Beginning at 175 °C	The condensate, collected at the surface, started to boil with the dissolved part of the test item.
Beginning at 190 °C	The test items colour became darker and no condensate was left.
Heated until 400 °C	Test item became black-grey and remained solid.
After cooling down	The test item remained black-grey and solid (powder).

Conclusions:

No boiling point could be determined as the substance decomposed before boiling.
