| Hazard Information | Back Directory | [General Description]
AMMONIUM SULFITE(10196-04-0) is a colorless crystalline solid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. AMMONIUM SULFITE(10196-04-0) is used in the manufacture of other chemicals, in medicine, and photography. | [Reactivity Profile]
AMMONIUM SULFITE is a reducing agent. Emits toxic sulfur dioxide and oxides of nitrogen when heated to decomposition [USCG, 1999]. | [Air & Water Reactions]
Soluble in water. | [Health Hazard]
Inhalation of dust causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Dust irritates eyes. | [Potential Exposure]
Ammonium sulfite is used in medicines,
metal lubricants; explosives, photography, hair wave
solutions; and to make other chemicals. It is also used as a
preservative, and for treating agricultural grain. | [Fire Hazard]
Special Hazards of Combustion Products: Toxic sulfur dioxide and oxides of nitrogen may form in fires. | [First aid]
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration
with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with running
water for at least 20 minutes. For minor skin contact,
avoid spreading material on unaffected skin. Keep victim
warm and quiet. Effects of exposure (inhalation, ingestion,
or skin contact) to substance may be delayed. Ensure that
medical personnel are aware of the material(s) involved
and take precautions to protect themselves. Medical observation
is recommended for 24 to 48 hours after breathing
overexposure, as pulmonary edema may be delayed. As first
aid for pulmonary edema, a doctor or authorized paramedic
may consider administering a drug or other inhalation
therapy. | [Shipping]
UN2693 Bisulfites, inorganic, aqueous solutions,
n.o.s., Hazard class: 8; Labels: 8-Corrosive material.
UN3077 Environmentally hazardous substances, solid, n.o.
s., Hazard class: 9; Labels: 9-Miscellaneous hazardous
material, Technical Name Required. | [Incompatibilities]
A strong reducing agent. Reacts violently
with strong oxidizers (chlorates, nitrates, peroxides,
permanganates, perchlorates, chlorine, bromine, fluorine,
etc.); contact may cause fires or explosions. Keep away
from alkaline materials, strong bases, strong acids, oxoacids,
epoxides. | [Chemical Properties]
Ammonium sulfite is a colorless to yellow crystalline
(sand-like or sugar-like) solid, normally sold or used
in a 40% solution. | [Chemical Properties]
Colorless to white crystals that are soluble in water (NH4)2S03H20 is used both as a reducing agent and in photography. This compound is a salt that can form from the reaction of ammonia and sulfur dioxide or hydrogen sulfide. This product is frequently found in the overhead of crude distillation units and can be quite corrosive to steel equipment. Chemical corrosion inhibitors are often used to control corrosion from ammonium sulfite and other ammonium salts
| [Waste Disposal]
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator
equipped with an afterburner and scrubber. All federal,state, and local environmental regulations must be
observed. May be buried in a chemical waste landfill in
accordance with federal, state, and local statutes; or, if oxidized
and neutralized, it may be sent to a municipal sewage
treatment plant for biological treatment Incineration. | [Physical properties]
Colorless monoclinic crystals. Soluble in water, its aqueous solution is alkaline. Slightly soluble in alcohol. Insoluble in acetone and carbon disulfide. It is easily oxidized to ammonium sulfate in air. It can be decomposed into ammonia and sulfur dioxide when heated. | [Uses]
Ammonium Sulfite is an additive used in the production of
caramel. | [Definition]
ChEBI: Diammonium sulfite is a p-block molecular entity and a sulfite salt. | [Preparation]
In the ATS process, sulfur dioxide is absorbed from incinerated Claus tail gas in aqueous ammonia to produce ammonium sulfite and ammonium bisulfite in solution. |
