Versuchsvorschrift

Hydrazine nitrate (HN) was prepared by reacting anhydrous hydrazine with an equivalent amount of ammonium nitrate. Formation took place by displacement of the ammonia as a gas. In production the ammonia would be scavenged by passing it through an aqueous nitric acid solution trap to form ammonium nitrate, which could then be used to prepare more HN. The HN product was purified by crystallization from methanol. This process was quite safe because it eliminated the need to neutralize the hydrazine with nitric acid. The procedure used is as follows.
