Sodium amide: HSNO Approval: HSR004679 Approved with controls

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.

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]

SODIUM AMIDE is a powerful reducing agent. Reacts violently with oxidizing agents. Reacts violently with steam and water to form caustic NaOH and NH3 vapors [Bergstrom et al., Chem. Reviews, 12:6 1932]. May form explosive compounds in the presence of water and carbon dioxide [Handling Chemicals Safely 1980 p 826]. Liable to deflagration upon heating and friction. Forms an explosive peroxide on storage. When sodium amide and chromic anhydride are mixed together a vigorous reaction results; the same occurs with other oxidizing agents including dinitrogen tetraoxide, potassium chlorate, sodium nitrite. [Mellor 11:234 1946-47]. Reaction with 1,1-diethoxy-2- chloroethane produces sodium ethoxyacetylide, which is extremely pyrophoric [Rutledge 1968 p. 35]. Reactions with halogenated hydrocarbons may be violently explosive. Sodium amide forms toxic and flammable H2S gas with CS2. (714).
