| Hazard Information | Back Directory | [General Description]
AMMONIUM SULFAMATE(7773-06-0) is a white crystalline solid. AMMONIUM SULFAMATE(7773-06-0) is soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. AMMONIUM SULFAMATE(7773-06-0) is used to flameproof fabrics and papers, in weed or brush killing products, and for other uses. | [Reactivity Profile]
AMMONIUM SULFAMATE is incompatible with the following: Acids, hot water [Note: Elevated temperatures cause a highly exothermic reaction with water (in the presence of acid).] . | [Air & Water Reactions]
Water soluble. Hot water [Note: Elevated temperatures cause a highly exothermic reaction with water (in the presence of acid)] . | [Hazard]
Hot acid solutions when enclosed may
explode.
| [Health Hazard]
Inhalation causes irritation of nose and throat. Ingestion causes gastrointestinal disturbances. Dust irritates eyes. | [Potential Exposure]
Ammonium sulfamate is used as a
herbicide and in compositions for retarding flame in textiles
and paper products; a softener for paper, cotton textiles. | [Fire Hazard]
Special Hazards of Combustion Products: Toxic oxides of nitrogen may form in fires. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at
least 15 minutes, occasionally lifting upper and lower lids.
Seek medical attention immediately. If this chemical
contacts the skin, remove contaminated clothing and
wash immediately with soap and water. Seek medical
attention immediately. If this chemical has been inhaled,
remove from exposure, begin rescue breathing (using
universal precautions, including resuscitation mask) if
breathing has stopped and CPR if heart action has
stopped. Transfer promptly to a medical facility. When
this chemical has been swallowed, get medical attention.
Give large quantities of water and induce vomiting.
Do not make an unconscious person vomit. | [Shipping]
UN3077 Environmentally hazardous substances,

material, Technical Name Required. | [Incompatibilities]
Strong oxidizers, potassium, potassium
chlorate, sodium nitrite, metal chlorates, and hot acid solutions.
Elevated temperatures cause a highly exothermic
reaction with water. | [Description]
Ammonium sulfamate (or ammonium sulphamate) (7773-06-0) is a white crystalline solid, readily soluble in water. It is a salt formed from ammonia and sulfamic acid. Based on its good performance, it is widely used in industrial production and scientific research. Ammonium sulfamate is used as a herbicide, a composting accelerator in horticultural settings, a flame retardant, and so on.
| [Chemical Properties]
Ammonium sulfamate is a white to yellow
crystalline solid. | [Chemical Properties]
white crystalline powder | [Waste Disposal]
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations governing
storage, transportation, treatment, and waste disposal.
Dilute with water, make neutral with acid or base and flush
into sewer with more water. | [Application]
Ammonium sulfamate could be widely used in pesticides, printing and dyeing, tobacco, building materials, textiles, and other industries. It could used as an analytical reagent. It could also used in the manufacture of fire-retardant compositions, for flameproofing textiles and paper products, and in the manufacture of weed-killing compositions. It is also used in electroplating solutions and could used for the generation of nitrous oxide gas. | [Uses]
Ammonium sulfamate (AMS) is an inorganic herbicide used for control of woody plants and herbaceous perennials. | [Uses]
In the manufacture of fire-retardant compositions, for flameproofing textiles and paper products; in the manufacture of weed killing compositions; in electroplating solutions; for the generation of nitrous oxide gas. | [Uses]
Manufacture of weed-killing compounds
and fire-retardant compositions | [Definition]
ChEBI: Ammonium sulfamate is an organic molecular entity. | [Preparation]
Ammonium sulfamate is prepared continuously, starting from ammonia and sulfur trioxide, in which liquid sulfur trioxide and liquid ammonia are introduced in a molar ratio NH3 /SO3 greater than 2.0:1 into a pressure reactor containing the reaction product in the molten state, excess ammonia being removed continuously from the reactor and the liquid sulfur trioxide being introduced into the melt.
| [Carcinogenicity]
The oral LD50 values were 3900 mg/kg for
rats and 5760 mg/kg for mice. | [Purification Methods]
Crystallise it from water at room temperature (1mL/g) by adding EtOH and cooling. [Sisler & Audrieth Inorg Synth II 180 1946.] |
