Type of method:
differential scanning calorimetry
Atm. press.:
ca. 1 013 hPa
Decomp. temp.:
ca. 165 °C
Remarks on result:
other: the decomposition is autocatalysed for pure and technical product

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.


Analytical grade

Technical grade

Decomposition temperature /°C



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.
