Guideline:

OECD Guideline 113 (Screening Test for Thermal Stability and Stability in Air)

Version / remarks:

DIN 51007

Principles of method if other than guideline:

Measurement by DSC with a heating rate of 2.5°C/min

GLP compliance:

yes (incl. QA statement)

Test substance thermally stable:

yes

The decomposition energy at 210°C was observed a value of 30 J/g. This small reaction energy could be affected by impurities.

1st reaction:

Onset temperature: 210°C

Peak temperature: 270°C

Energy release: 30 J/g

2nd reaction:

Onset temperature: 420°C

Peak temperature: 439°C

Energy release: 40 J/g

No exothermic effect on test substance found below 150 °C.Thus the test substance is considered to be stable at room temperature based on the criteria as outlined in the OECD Guideline 113.

Conclusions:

The test substance is thermally stable at room temperature.

Description of key information

Thermally stable at room temperature

Additional information

The determination was performed by DSC according to DIN 51007.

No thermal effect on test substance found below 150 °C thus the test substance is considered stable at room temperature based on the criteria as outlined in the OECD Guideline 113.
