- Conclusions:
- The test substance showed endothermic effects in the temperature ranges 35 -80 °C, 225 -270 °C (double peak) and 305 - 320 °C and no exothermal effects up to the maximum test temperature of 400 °C
- Executive summary:
Thermal stability of was determined according to a guideline study, using differential scanning calorimetry (Mettler-Toledo TA8000).The test substance and the standard reference substance were heated up from room temperature to the final temperature (360°C) in closed glass crucible at a constant heating rate (3K/min) under nitrogen. The quantity of heat absorbed or given off was measured and recorded. Approximately 11 mg of the test substance was used. The test substance showed endothermic effects in the temperature ranges 35 -80°C, 225 -270°C (double peak) and 305 - 320°C and no exothermal effects up to the maximum test temperature of 400°C ( Smeykal, 2008)
Reference
Individual Results
ThermalStability(DSC): Two DSC-measurements in closed glass crucibles with the test substance showed endothermic effects in the temperature ranges 35 - 80°C, 225 -270°C (double peak) and 305 -320°C and no exothermal effects upto the maximum test temperature of 400°C. Graphical presentations of the DSC runs No.28037 and No.28038 are given on page 7 (figure1).
Description of key information
The test substance showed endothermic effects in the temperature ranges 35 -80 °C, 225 -270 °C (double peak) and 305 - 320 °C and no exothermal effects up to the maximum test temperature of 400 °C.
Additional information
The thermal stabilty and stability in air of the test substance was determined using the differential scanning calorimetry according to OECD guideline 113 (Franke, 2002).
Justification for classification or non-classification
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).
