Regulatory Information
Chemical: Sodium amide (Na(NH2))
Status: Active Update: 25-10-2022 https://echa.europa.eu/registration-dossier/-/registered-dossier/11165
Sodium amide: HSNO Approval: HSR004679 Approved with controls
DOT LabelDangerous When Wet
Fire HazardsSpecial Hazards of Combustion Products: Toxic and irritating ammonia gas may be formed. (USCG, 1999)
Fire Potential
FLAMMABLE, DANGEROUS FIRE RISK.
The reduction with 1,1-diethoxy-2-chloroethane in the presence of ammonia produces sodium ethoxyacetylide, which is extremely pyrophoric. Sodium amide reacts violently with water and frequently bursts into flame.
Health HazardsAmmonia gas formed by reaction of solid with moisture irritates eyes and skin. Solid causes caustic burns of eyes and skin. Ingestion burns mouth and stomach in same way as caustic soda and may cause perforation of tissue. (USCG, 1999)
Hazards Summary
Emergency treatment: Corrosives- alkaline; [HSDB] Reacts violently with water producing sodium hydroxide and ammonia; Oxidation products after air exposure may be highly explosive; A severe skin, eye, and mucous membrane irritant; [Merck Index] A strong reducing agent; An explosive peroxide may be produced on storage; May cause caustic burns to skin and eyes; [CAMEO] Reacts violently with water evolving highly flammable gases; Explosive on contact with oxidizing substances; A highly corrosive substance that can cause injury to the skin, eyes, and respiratory tract; Inhalation may cause chemical pneumonitis; [Alfa Aesar MSDS]

응용 분야
용도Sodium Amide is widely used in organic chemical synthesis as a strong base in reactions such as in the preparation of phenylacetylene from 1,2-dibromophenylethane. Also used in the synthesis of 2,6-diamination of substituted pyridines as initiator of heterogeneous chichibabin reaction.
일반 설명Odorless colorless solid. Denser than water.
제조 방법
Sodium amide is prepared by passing dry ammonia gas over sodium metal at 350°C: 2Na + 2NH3 → 2NaNH2 + H2Also, it may be prepared by reacting sodium metal with liquid ammonia in the presence of a catalyst such as iron(III) nitrate. The compound must be stored in well-sealed containers free from air or moisture.
