Boiling point

Link to relevant study record(s)

Reference

Endpoint:

boiling point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

14 June 2018

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

OECD Guideline 103 (Boiling Point)

Version / remarks:

27 July 1995

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Type of method:

photocell detection

Specific details on test material used for the study:

- Storage conditions: The test material was stored in a dark storage place at room temperature.
- Test material identification and stability under storage: The infrared (IR) spectrum of the test material measured at the test facility was confirmed to be identical to that provided by the sponsor. In addition, the IR spectrum of the test material after the completion of the experiment was the same as that before the start of the experiment, and it indicated that the test material was stable under storage conditions.

Key result

Remarks on result:

not determinable

Remarks:

There is no boiling point of the test material because the test material changes at about 265 °C.

No information was provided on atm pressure. It is assumed that the measurements were performed at standard atmospheric pressure.

Conclusions:

Under the conditions of this study there is no boiling point of the test material because the test material changes at about 265 °C.

Executive summary:

The boiling point of the test material was investigated according to the standardised guideline OECD 103 and under GLP conditions, following the photocell detection method.

The test material was heated to 300 °C and visual observation was performed.

Under the conditions of this study there is no boiling point of the test material because the test material changes at about 265 °C.

Description of key information

The boiling point of the test material cannot be determined because the test material changes at about 265 °C.

Additional information

The boiling point of the test material was investigated according to the standardised guideline OECD 103 and under GLP conditions, following the photocell detection method. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

The test material was heated to 300 °C and visual observation was performed.

Under the conditions of this study there is no boiling point of the test material because the test material changes at about 265 °C.
