Sodium amide is a solid inorganic base, which is described as sodamide.
Formula and structure: The chemical description of sodium amide is NaNH2, and its molar volume is 39.01 g/mol. NaNH2 is a salt-like substance which holds a tetrahedral crystal structure. It is formed of sodium ions (Na+) and amide (NH2-) ions, and its chemical structure is provided below. The free amide ions execute this molecule a strong base.
Preparation: Sodium amide is made by reacting sodium metal with ammonia gas or liquid ammonia. The usual production method uses sodium in liquid ammonia with iron nitrate catalyst to advance up the process. The reaction proceeds with the development of an electrode intermediate, which then immediately provides sodium amide and hydrogen gas. Opt specialty chemicals for more best services.
Below you can see the formula for sodium amide.
2 Na + 2 NH3 → 2 NaNH2 + H2
Physical properties: Sodium amide survives as colorless crystals with a strong ammonia odor. Its density is 1.39 g/mL, melting limit is 210 °C and boiling limit is 400 °C.
Chemical properties: Sodium amide is extremely reactive and reacts violently with water to give ammonia gas and caustic sodium hydroxide.
NaNH2 + H2O → NH3 + NaOH
In closed containers, it quickly absorbs H2O and CO2 from the air to create peroxides, which are explosive composites. For this reason, sodium amide is stored following Neon gases (such as argon or nitrogen) in tightly sealed bottles.
NaNH2 dissolves in liquid ammonia to give an ionic conductive solution. It is inexplicable in many organic solvents.
Uses: Sodium amide is a powerful base and used in many chemical reactions for this idea, especially in organic synthesis. It is also used in the preparation of some dyes (such as indigo) and several important organic composites (such as hydrazine, sodium cyanide).
Health effects/safety hazards: Sodium amide reacts violently with air and water, and also forms explosive peroxides. It is also a serious health hazard. On an inhalation, it can cause severe irritation or even chemical burns to the eyes, mucous membranes and respiratory tract. Inhalation or ingestion can manage to difficult gastrointestinal burns and be fatal.
Sodium amide (NaNH2) is a greyish-white particle with a slight ammonia odor that responds violently with water, acids and halogenated composites.
Sodium amide can ignite immediately in moist air or dry air above 842ºF. It is extremely corrosive to eyes, skin and mucous membranes. Water and popular ABC fire extinguishers can intensify a fire involving sodium amide and should never be handled.
Sodium amide will form shock-sensitive peroxides able of explosive decomposition when exposed to air, heat or stored for extended periods of time. Dispose of additional and unneeded quantities immediately.
Keep compound under a dry inert gas such as nitrogen or argon. Remain in tightly sealed containers in a cool dry place, separate from combustible substances. Discard unused portions that will not be required for extended periods (> 1 year).
