Observed thermic processes:
The test item also shows a glass transition at about -88°C followed by the exothermic recrystallization at about -10°C peak
temperature (Test 1).
In order to survey the thermic behaviour of the test item a preliminary DTA/TG-test (non-GLP) was run up to 700°C.
An endothermic peak starting at about 100°C with the weight loss up to 100% shows the vaporization / decomposition of the test item.
The estimated accuracy is ± 1°C.
Description of key information
The melting point of N,N'-bis(3-aminopropyl)ethylenediamine is -5 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -5 °C
