Chemische Eigenschaften
Ammonium sulfamate is a white to yellow
crystalline solid.
Verwenden
Ammonium sulfamate (AMS) is an inorganic herbicide used for control of woody plants and herbaceous perennials.
Allgemeine Beschreibung
Ammonium sulfamate is a white crystalline solid. Ammonium sulfamate 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 is used to flameproof fabrics and papers, in weed or brush killing products, and for other uses.
Air & Water Reaktionen
Water soluble. Hot water [Note: Elevated temperatures cause a highly exothermic reaction with water (in the presence of acid)] .
Reaktivit?t anzeigen
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).] .
Hazard
Hot acid solutions when enclosed may
explode.
Health Hazard
Inhalation causes irritation of nose and throat. Ingestion causes gastrointestinal disturbances. Dust irritates eyes.
Brandgefahr
Special Hazards of Combustion Products: Toxic oxides of nitrogen may form in fires.
Sicherheitsprofil
Moderately toxic by
ingestion and intraperitoneal routes.
Somewhat explosive when heated or by
spontaneous chemical reaction in a hot acid
solution. A powerful oxidizer. When heated
to decomposition it emits very toxic fumes
of NH3, NOx, and SOx. See also
SULFONATES and SULFAMIC ACID.
m?gliche Exposition
Ammonium sulfamate is used as a
herbicide and in compositions for retarding flame in textiles
and paper products; a softener for paper, cotton textiles.
Carcinogenicity
The oral LD50 values were 3900 mg/kg for
rats and 5760 mg/kg for mice.
Versand/Shipping
UN3077 Environmentally hazardous substances,
solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous
material, Technical Name Required.
l?uterung methode
Crystallise it from water at room temperature (1mL/g) by adding EtOH and cooling. [Sisler & Audrieth Inorg Synth II 180 1946.]
Inkompatibilit?ten
Strong oxidizers, potassium, potassium
chlorate, sodium nitrite, metal chlorates, and hot acid solutions.
Elevated temperatures cause a highly exothermic
reaction with water.
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.
