Example text
A common explosive composition called C4, is a mixture containing about 96% RDX, and about 4% plasticizer. It should be noted that inert fillers like plasticizers are added to secondary explosives to make uniform compositions with specific physical properties—all depending upon certain environmental conditions. One such example is demonstrated by high velocity explosive projectiles—such that as artillery shells, and tank fired projectiles. High velocity explosive compositions require a high degree of stability combined with long-term storage ability.
Carbon tetrachloride is insoluble in water, but miscible with alcohol, benzene, chloroform, ether, and carbon disulfide. Carbon tetrachloride is a potential poison, and inhalation, ingestion, and skin absorption should be avoided at all cost. Carbon tetrachloride may be a carcinogen. It is prepared on an industrial scale by the chlorination of methane, but can be conveniently prepared by reacting chlorine with carbon disulfide in the presence of iron fillings; the carbon tetrachloride is recovered by distillation.
Acetonitrile is toxic by inhalation or skin absorption. Acetyl chloride Acetyl chloride Acetyl chloride is a colorless, flammable liquid with a pungent irritating odor. It has a melting point of –112 Celsius, and a boiling point of 52 Celsius. The liquid is highly irritating to the eyes. It decomposes violently with water or alcohol. Acetyl chloride is miscible with benzene, chloroform, ether, glacial acetic acid, and petroleum ether. It can be prepared by treating sodium acetate with sulfuryl chloride, or by the action of phosphorus trichloride upon glacial acetic acid, and distilling the resulting mixtures.
