Hydrazine (anhydrous) exhibits flammable, explosive, and toxic properties. It is a flammable liquid and bums in air with a violet flame the closed cup flash point is 38°C ( 100°F). The vapors of hydrazine form explosive mixtures with air over a very wide range, between 4.7 and 100% by volume in air. It ignites spontaneously when brought in contact with many porous substances, such as earth, wood, or cloth. Ignition occurs on contact with many metal oxide surfaces and on mixing with oxidizers such as nitric acid or hydrogen peroxide. It forms shock-sensitive explosive products when combined with metal perchlorates, alkali metals, or their dichromates. Spontaneous ignition occurs with fluorine, chlorine, bromine vapors, or nitrous oxide. 

The specific gravity of liquid explosives must be greater than 1.2, so that the treatment after failure detonation could be facilely finished and the water solubility is also good. The specific gravities of liquid explosives with main oxidizers of urea perchlorate, hydrazine nitrate, and hydrazine perchlorate are listed in Table 1.4. Metal perchlorates are also main components for liquid explosives [31, 32]. 

Method II Magnesium perchlorate hydrazine can also be prepared by the reaction of stoichiometric quantities of magnesium powder with ammonium perchlorate dissolved in hydrazine hydrate (1 2 2 ratio, respectively) at room temperature. Magnesium metal dissolves exothermically with the evolution of hydrogen. The solid compound is obtained by the addition of alcohol ( 96% yield) ... 

Transition metal perchlorate, nitrate, and azide hydrazines are explosives. They are sensitive to friction and impact. Nickel perchlorate hydrazine is reported to be explosive even under water. Metal hydrazine complexes of azide and nitrate are highly sensitive to impact and friction and so decompose violently. Table 6.5 summarizes the impact sensitivities of these complexes as determined by the drop weight method [9]. 

Numerous explosives are based on hydrazine and its derivatives, including the simple azide, nitrate, perchlorate, and diperchlorate salts. These are sometimes dissolved in anhydrous hydrazine for propeUant appUcations or in mixtures with other explosives (207). Hydrazine transition-metal complexes of nitrates, azides, and perchlorates are primary explosives (208). 

Metal compounds containing both coordinated ammonia, hydrazine, hydroxylamine or similar nitrogenous donors, and coordinated or ionic perchlorate, chlorate, nitrate, nitrite, nitro, permanganate or other oxidising groups will decompose violently under various conditions of impact, friction or heat [1,2]. From tabulated data for 17 such compounds of Co and Cr, it is considered that oxygenated A-coordinated compounds, (particularly those which are oxygen balanced) cover... 

Perchloryl fluoride is a non corrosive gas with a sweet taste. It has a melting point of -148 Celsius and a boiling point of -47 Celsius. Perchlorly fluoride is a very stable gas at room temperature. Explosions will result if perchloryl fluoride is treated with reducing agents such as amides, powdered metals, hydrides, sulfites, phosphites, phosphides, or hydrazines or when treated with alcohols. Avoid skin contact and inhalation.
