Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study without detailed documentation
- Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- GLP compliance:
- yes
- Type of method:
- differential thermal analysis
- Boiling pt.:
- °C
- Decomposition:
- yes
- Decomp. temp.:
- >= 180 °C
- Conclusions:
- At 180 °C an endotherm peak was observed which noisy shape indicates decomposition of the substance. There is no indication of a of a boiling point prior to decomposition.
- Executive summary:
The boiling temperature of the substance was determined by differntial scanning calorimetry according to EU-method A.2 (Boiling temperature). No boiling point prior to decomposition was found.
Reference
A preliminary thermographic measurement was performed over a temperature range from room temperature to 250 °C. The thermographic curve exhibits two ranges. Between room temperature and approximately 170 °C the sample lost 5.7 % of its weight; another 0.8 % was lost during purging before the start of the measurement. This weight loss was probably due to evaporation of strongly bound moisture.
Beginning at approximately 180 °C the mass loss rate increased steadily, reaching a maximum at approximately 227 °C. At the final temperature of 250 °C the sample was still continuously loosing mass. The mass loss between 170 and 250 °C was 24.7 %. The residue looked orange brown and blended.
The DSC measurement was performed twice:
To determine a possible boiling point more precisely a crucible lid with one hole of 50 µm was used in the first measurement. The small hole causes generation of a defined atmosphere at constant pressure inside the crucible and allows measurements at near equilibrium conditions, thus preventing evaporation of the test material before reaching the boiling point. The measurement was stopped at a temperature of approximately 250 °C after a sudden endothermic peak at 201 °C indicated a burst crucible. The course of the DSC curve suggests that at approximately 150 °C the small hole was clogged.
The second measurement was therefore performed in an "open" crucible with a pierced lid. The sample had lost approximately 64.9 % of of its mass at the end of the second measurement with a dark brown residue on the bottom of the crucible.
Description of key information
No boiling point could be determined. The substance decomposes at temperatures >= 180 °C.
Key value for chemical safety assessment

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
