What You Need To Know About Sodium Amide?

Sodium amide -1H2 is a valuable catalyst for decomposing NH3 into H2 and N2, but -1H2, which is commercially available, is all present and usually contains impurities of NaOH (< 2%).

Sodium amide Formula

Sodium amide, also referred to as sodamide, is a solid inorganic base.

Formula and structure:-1H2 and 39,01 g / mol of its molar mass are the sodium chemicals amide. -1H2 is a salt-like, tetrahedral-crystal-like material. The chemical structure is shown below and contains sodium (Na+) and amid (NH2-) ions. This molecule is made up of free amide ions.

Preparation: Sodium amide is made with ammonia gas or liquid ammonia by means of a sodium metal reaction. In fluid ammonia with iron nitrate catalyst, the common method of production uses sodium for accelerating the process. The reaction begins with the formation of an intermediate electrode, which gives sodium amide and hydrogen gas quickly.

Below is the formula 

2 Na + 2 NH3 → 2 NaNH2 + H2

Physical characteristics: Sodium amide has strong ammonia odour as colorless crystals. The density of the melting is 1.39 g / mL, 210 ° C and 400 ° C boiling.

Chemicals: Sodium amide is highly reactive and strongly reacts to the production of ammonia gas and caustic sodium hydroxide with water.

They easily absorb H2O and carbon dioxide from air into peroxides that are explosive compounds in closed containers. Sodium amide is therefore contained in tightly sealed containers in inert gasses (e.g., argon or nitrogen). To give an ionic conductive solution, -1H2 dissolves in liquid ammonia. In many organic solvents it is insoluble. Sodium hydride and sodium amide are related to each other. And they have their inter relation which are made with their own formula.

Uses: Sodium amide is a strong basis and is used for this purpose in many chemical reactions, especially organic syntheses. It is also used in certain dyes (e.g. indigo) and a variety of essential organic compounds (e.g. hydrazine, sodium cyanide).

Safety / Health Effects: Sodium amide has a strong air / water reaction and is also explosive peroxides. It also constitutes a serious health risk. During inhalation, the skin, mucous membranes and respiratory tract may be extremely irritated or even chemical burned. Inhalation or ingestion can lead to serious and fatal gastrointestinal burns.
