GLP compliance:
yes (incl. QA statement)
Type of method:
differential scanning calorimetry
Decomposition:
yes
Remarks:
The unsteady base line and inconstant thermal (approx. 230 °C and 450 °C) effects could be interpreted as decomposition (> 230 °C) of the test item.
Decomp. temp.:
> 230 °C
Remarks on result:
other: could be interpreted as decomposition

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.

Conclusions:
Since no steep endothermic signal could be detected for HPP 12879-1 there is no indication for a definite boiling point. The unsteady base line and inconstant thermal (approx. 230 °C and 450 °C) effects could be interpreted as decomposition (> 230 °C) of HPP 12879-1.
Executive summary:

A Differential Thermal Analysis (DTA) / Differential Scanning Calorimetry (DSC) was used to determine the boiling point of HPP 12879 -1. Between approx. 230 °C and 320 °C and approx. 330 °C and 450 °C 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 (approx. 230 °C and 450 °C) effects could be interpreted as decomposition (> 230 °C) of HPP 12879 -1.

Description of key information

Since no steep endothermic signal could be detected for HPP 12879-1 there is no indication for a definite boiling point. The unsteady base line and inconstant thermal (approx. 230 °C and 450 °C) effects could be interpreted as decomposition (> 230 °C) of HPP 12879-1.
