Results and discussion

Melting / freezing point
Melting / freezing pt.:
85 °C

Any other information on results incl. tables

Study was performed without adjustment of atm. pressure.

Observed thermic processes:

A reproducible glass transition was found at -51 °C in the 2nd heating.

In order to survey the thermic behaviour of the test item one determination was run up to 500°C. Exothermic decomposition was not observed.

One endothermic peak starting at about 250°C (determination "Test"), with the registered loss of mass shows the vaporization of the test item.

The estimated accuracy is +/- 2°C.
