Additional information

EEA-NH4 is a white, odourless powder. The melting point is 95.8 °C, the boiling point is 181.0 °C and the density is 1355 kg.m-3at 20 °C.

The vapour pressure is 1.63 x 10-5mmHg, the log Kowis 1.18 and the water solubility is 516 mg.L-1(all software predictions).

The surface tension is 59.1 mN.m-1at 21 °C at a concentration of 90% in distilled water. The self-ignition temperature of the substance is > 400 °C (no exothermic activity was observed). The substance is not flammable and does not have explosive and oxidising properties.

Determination of the granulometry showed that:

10% of material is < 236.831 µm

50% of material is < 716.488 µm

90% of material is < 1416.196 µm

0.47% by volume of sample was seen to be < 10.00 µm.


All physical and chemical properties have been tested by Chilworth Technology Ltd (2008).
