- Test substance thermally stable:
- no
- Remarks:
- The unsteady base line and inconstant thermal effects wihin the DTA/DSC could be interpreted as decomposition of the test item.
- Operating temp.:
- >= 25 - <= 450 °C
- Conclusions:
- The unsteady base line and inconstant thermal effects within the DTA/DSC could be interpreted as decomposition of the test item.
- Executive summary:
A thermal stability study according to OECD 113 was performed. HPP 12879 -1 was heated up from 25 °C to 450 °C (heating rate 5 K/min) in a DTA/DSC-system. The substance is thermally not stable.
Two endothermic effects were visible between approx. 30 °C and 95 °C indicating a large melting range.
Between approx. 230 °C and 320 °C and approx. 330 °C and 450 °C further endothermic effects were observed. The unsteady base line and inconstant thermal effects within the DTA/DSC could be interpreted as decomposition of the test item.
Reference
At room temperature the substance is solid.
Between 25 °C and 450 °C no definite melting could be observed. In the same temperature range no definite boiling point was detectable.
Two endothermic effects were visible between approx. 30 °C and 95 °C indicating a large melting range.
Between approx. 230 °C and 320 °C and approx. 330 °C and 450 °C further endothermic effects were observed. Since no steep endothermic signal could be detected there is no indication for a definite boiling point. The unsteady base line and inconstant thermal effects could be interpreted as decomposition of the test item.
Description of key information
The unsteady base line and inconstant thermal effects within the DTA/DSC could be interpreted as decomposition of the test item.
