Sodium Amide
Overview
Sodium amide (NaNH2) is a greyish-white powder with a slight ammonia odor that reacts violently
with water, acids and halogenated compounds. Sodium amide can ignite spontaneously in moist
air or dry air above 842 F. It is highly corrosive
to eyes, skin and mucous membranes. Water and conventional ABC fire
extinguishers can intensify a fire involving sodium amide and should never be
used. Sodium amide will form shock sensitive peroxides capable of exposive decomposition when exposed to air, heat or stored for extended periods of time. Disposed of unused and unneeded quantities immediately.
Emergency Procedures
Skin/Eye Contact: Brush
off any visible solids. Rinse with copious amounts of water
for at least 15 minutes. Seek medical attention as needed. Thoroughly
clean clothing before reuse.
Ingestion:
Will react immediately with saliva to cause serious burns and possible local combustion and even explosion of hydrogen in the mouth or esophagus. Do not induce vomiting. Drink 2-3 glasses of water and seek medical
attention immediately.
Inhalation:
Causes severe burns to mucuous membranes. Risk of death from pulmonary edema. Move to fresh air immediately. Do not administer mouth to mouth resuscitation. Seek medical attention immediately
Fire: Use
Class D extinguisher such as Met-L-X or smother the fire
with dry sand and/or soda ash. Do not use water, carbon dioxide or halogenated
extinguishing agents.
Spill: Control
all sources of ignition. Wearing personal protective equipment,
cover the spill with sand. Scoop spilled materials with spark-resistant
tools and place in a container for disposal. DO NOT USE WATER
or combustible materials, such as saw dust.
Handling
Wear safety glasses, impervious gloves and a fire-retardant laboratory
coat.
Control ignition sources and avoid dust formation. Avoid contact with
water or moisture. Keep a supply of dry sand available in the
work area and ensure there is a Class D extinguisher immediately available.
When large quantities of sodium amide will be used, work under an
inert gas, such as nitrogen or argon, in a fume hood or glove box. Avoid
contact with air, water or moisture.
Sodium amide is incompatible with oxygen, carbon dioxide, halogens and halogenated solvents, alcohols, oxidizing
agents, hydrated salts, acids and a wide variety of other materials. Sodium amide reacts violently
on contact with powerful oxidizers and water.
Do not grind sodium amide or heat it. Upon contact with water, acids
or alcohols, potassium produces an exothermic reaction involving release
of
flammable hydrogen gas. Peroxidized sodium amide may explode upon handling.
Storage
Keep compound under dry inert gas such as nitrogen or argon. Store in tightly sealed containers in a cool dry place, separate from
combustible materials.
Discard unused portions that will not be needed for extended periods of time (> 1 year)
Disposal
Store wastes in tightly sealed containers under dry inert gas. Used reagent can be deactivated under controlled environments. Dispose as hazardous
waste. CONTAINERS OF SODIUM AMIDE THAT HAVE FORMED PEROXIDES MUST NOT BE HANDLED. Yellow or brown colored solids are evidence of contamination with peroxides. Contact James Boehlert (EHS) at 8-7882 immediately.
