Ammonium sulfide Usage And Synthesis
Chemical Properties yellow to orange fuming liquid
Chemical Properti
es
Ammonium sulfide is a yellow crystalline (sugar or sand-like) material, commonly found in
liquid solution, which is flammable. Solution has an odor of rotten eggs.
Chemical Properties The distinct ammonical/sulfurous odor of ammonium sulfide makes it a valuable flavor ingr
edient. It is used in baked goods, meat products, condiments and gravies.
Physical properties Unstable, decomposes at ambient temperature; forms yellow crystals below -18°C; hygros
copic; soluble in water and alcohol, very soluble in liquid ammonia.
Uses To apply patina to bronze, in photographic developers, in textile manufacture, in trace met
al analysis.
General Descriptio
n
Ammonium sulfide aqueous solution is a colorless to yellow liquid, with an odor of rotten e
ggs or ammonia. Material in aqueous from the hydrosulfide which with acid forms H2S. A
mmonium sulfide may be irritating to skin, eyesand mucous membranes and may cause il
lness from skin absorption. Ammonium sulfide may burn and/or emit toxic fumes if heated
to high temperatures.
Air & Water Reactio
ns
Readily oxidized to be pyrophoric in air [Bretherick 1979 p. 120]. Ammonium sulfide is slo
wly decomposed by moisture giving off hydrogen sulfide, a flammable gas. Heat is genera
ted when the pure compound is first dissolved in water.
Reactivity Profile AMMONIUM SULFIDE SOLUTION is a strongly alkaline aqueous solution. Reacts with ac
ids to generate toxic gaseous hydrogen sulfide. Reacts with bases to release gaseous am
monia. May react vigorously with oxidizing agents, including inorganic oxoacids, organic p
eroxides and epoxides. Special Hazards of Combustion Products: Toxic hydrogen sulfide
gas is released when solution is heated. If ignited, this will form irritating sulfur dioxide gas
[USCG, 1999].
Health Hazard Inhalation of 500 ppm for 30 min. produces headaches, dizziness, bronchial pneumonia; 6
00 ppm for 30 min. can cause death. Ingestion causes severe irritation of mucous membr
anes and stomach. Contact with liquid causes severe burns of eyes and severe skin irritati
on. May be absorbed through skin and cause hydrogen sulfide poisoning.
Fire Hazard Special Hazards of Combustion Products: Toxic hydrogen sulfide gas is released when sol
ution is heated. If ignited, this will form irritating sulfur dioxide gas.
Industrial uses Ammonium sulfide (NH4)2S is a liquid with an obnoxious odor and because of this, it is not
normally used in mineral processing. However, this is the most effective depressant for bo
rnite and covellite. Essentially, (NH4)2S dissolves excess sulfur from the mineral surface, t
hat allows other depressants to adsorb onto the mineral surface. In copper–lead separatio

n, from a bulk concentrate containing covellite and bornite, (NH4)2S can effectively be use
d together with cyanide.
Potential Exposure It is used in photographic developers, synthetic flavors, coloring metals (i.e., to apply patin
a to bronze); and to make textiles.

Incompatibilities Vapor form explosive mixture with air Incompatible with oxidizers (chlorates, nitrates, pero
xides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause f
ires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacid
s, epoxides. Evolves poisonous ammonia on contact with strong bases. Contact with acid
or acid fumes releases hydrogen sulfide. Keep away from moisture.
Waste Disposal Add to a large volume of ferric chloride solution with stirring. Neutralize with soda ash. Flu
sh to drain with water.
