- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry
- Atm. press.:
- ca. 1 013 hPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 165 °C
- Remarks on result:
- other: the decomposition is autocatalysed for pure and technical product
Reference
Preliminary tests showed significant exothermic process. The decomposition corresponding to an exothermic process began at about 165 °C for pure grade and the technical grade. The both exothermic processes were found to be auto-catalytic.

There are no values given for pressure but assumed to be measured at normal pressure (1013 hPa).
Description of key information
decomposition temperature: ca. 165 °C at ca. 1013 hPa
Key value for chemical safety assessment
Additional information
The boiling point for the test item could not be determined due to decomposition at ca. 165 °C. The decomposition is autocatalysed for pure and technical product. Differential scanning calorimetry according to OECD Guideline 103 was used.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
