7782-92-5 - Physical and Chemical Properties:

Sodium Amide (CAS: 7782-92-5), Unstable in air, easy to oxidation. Heating oxidation of sodium hydroxide, sodium nitrite and ammonia. Decomposition begins at 400℃, and rapidly decomposes at 500-600℃. Deliquescence, and water intense reaction to generate ammonia and sodium hydroxide. Decomposition in hot alcohol. Decomposition to nitrogen, sodium, hydrogen and ammonia was achieved by heating to 300-330℃ in a vacuum. Toxic! Flammable and explosive. Corrosive.

7782-92-5 - Application:

Sodium Amide (CAS: 7782-92-5) is widely used in organic chemical synthesis. 1. Sodium Amide can be used as the condensation accelerator in organic chemical reactions. It is raw material in synthesis of vitamin A. Sodium Amide can be also used as dehydrating agent, dehalogenating agent, alkylating agent, ammoniated agent. In liquid ammonia, the dissociation of NHf in liquid ammonia can be used as initiator of anionic polymerization producting polyvinyl chloride ion. Sodium Amide is also used in the manufacture azides, cyanide, hydrazine, and indigo. 2. Sodium Amide can be used as condensation-accelerating agent in organic synthesis, dehydration and the like. 3. For making NaCN, organic synthesis and pharmaceutical manufacturing. 4. In the production of indigo and hydrazine. Intermediate in the preparation of sodium cyanide. In ammonolysis reactions, in Claisen condensations, alkylation of nitriles and ketones, synthesis of ethynyl Compounds, acetylenic carbinols. 5. Sodium Amide is a powerful reducing agent. Reacts violently with oxidizing agents.

7782-92-5 - Preparation Method:

High temperature method: sodium metal is melted at 97~100℃, dehydrated liquid ammonia is slowly introduced, and the reaction is carried out at 350~360℃ to form sodium amino acid and hydrogen, and the reaction time is 6.5 hours, when it was checked that there was no metallic sodium present, the ammonia flux was stopped and the reaction was completed. After the reaction, it was cooled, condensed into thin slices, and then crushed to obtain sodium amino acid product, which was vacuum packed.
Low-temperature synthesis: the raw material is the same as the high-temperature method, and the reaction temperature is -30℃., which is synthesized in the presence of a metal catalyst.

7782-92-5 - Safety:

Outside the package, there shall be clearly marked_wet flammable solid-"toxic" text and icons, as well as the provisions of the goods must be written description. Store in a cool, dry warehouse. Should avoid contact with air, water, fire, in order to avoid explosion and fire. It should be kept in a closed form and protected from moisture. Storage time should not be too long. Handling is to be careful to handle, so as not to damage the package. Cover with tarpaulin during transportation in case of sun and rain.

Hazards and protection: dust is toxic, can cause corrosive burns, can seriously stimulate the eyes, skin and respiratory system. Wear gas masks and gloves when disposing of the escaping materials, mix them with dry sand and send them to an open place, and release them to the wastewater system after reacting with a large amount of water. Water should also be applied to the contaminated ground; Skin contact, eye irritation, should be immediately washed with water; Wrong in the mouth, should immediately rinse, drinking water and vinegar or 1% acetic acid, then the patient was sent to the hospital for treatment. After working in a high dust environment, take a bath and change clothes, store protective equipment separately, and often change. In case of fire, it can be controlled by dry sand, dry powder, carbon dioxide fire extinguishing or asbestos cloth.
