Et-NENA has a highly positive ΔHf. The NENAs utilize both nitramines and nitroesters as sources of their energy. They have been demonstrated to enable propellants to exhibit high burn rates yet retain low flame temperatures.

Interpretation of results:
study cannot be used for classification
Conclusions:
The substance Et-NENA has a differential scanning calorimetry (DSC) exotherm of 210ºC and a heat of formation (ΔHf) of 784 kJ/mol.
