Hydrazinium perchlorate monohydrate

Anhydrous hydrazinium perchlorate N2H5CIO4 has been prepared by the neutralization of N2H4 H2O (99.5%) with 60% perchloric acid at 0°C [4]. Hydrazinium perchlorate monohydrate (N2H5CIO4 H2O) and hydrazinium perchlorate hemihydrate (N2H5CIO4 O.5H2O) are prepared by the reaction of ammonium perchlorate with hydrazine hydrate [6] ... 

Hydrazinium perchlorate monohydrate is a white crystalline solid that melts at around 137°C to a colorless liquid. Anhydrous hydrazinium perchlorate N2H5CIO4 is also prepared by the dehydration of N2H5CIO4 O.5H2O kept in an air oven at 100 °C for 5h.

Hydrazine perchlorates are of interest due to their possible use as solid propellant oxidizers. Hydrazine forms two different perchlorates, depending on the degree of protonization. Hydrazinium (l-E) perchlorate (N2H5CIO4) forms N2H5CIO4 monohydrate and hemihydrate. The divalent (2-I-) perchlorate forms hydrazonium perchlorate, N2H6(C104)2. Because both salts are high explosives, their preparation has to proceed with extreme precaution. Hydrazinium perchlorates can be sublimed under vacuum without decomposition.
