Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
5 October 2017 - 9 November 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 103 (Boiling Point)
Version / remarks:
July 27, 1995
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.2 (Boiling Temperature)
Version / remarks:
March 04, 2016
Deviations:
no
GLP compliance:

Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Source and lot/batch No. of test material: 1704HH0700/0
- Expiration date of the lot/batch: 29th April 2018
- Purity test date: Not indicated

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Room temperature
- Stability under test conditions: No specific conditions required
Decomposition:
yes
Decomp. temp.:
> 175 °C

An exothermic peak was observed starting at 175°C. The endothermic effect was most likely due to reaction and/or decomposition of the test item.

After the experiment, a colourless residue remained in the sample container.

Conclusions:
Reaction and/or decomposition of the test item was observed at temperatures of > 175°C (> 448K). Boiling of the test item was not observed below the temperature of which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
Executive summary:

Reingruber (2017) is a GLP-compliant study following OECD guideline 103 and is therefore reliable without restrictions (Klimisch 1). Differential scanning calorimetry was used and showed reaction and/or decomposition of the test item at temperatures of > 175°C (> 448K). Boiling of the test item was not observed below the temperature of which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.

Description of key information

Reaction and/or decomposition of the test item was observed at temperatures of >175°C (> 448K).  Boiling of the test item was not observed below the temperature of which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
175 °C
