General Description
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 Reactions
Water soluble. Hot water [Note: Elevated temperatures cause a highly exothermic reaction with water (in the presence of acid)] .
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).] .
Hazard
Hot acid solutions when enclosed may
explode.
Health Hazard
Inhalation causes irritation of nose and throat. Ingestion causes gastrointestinal disturbances. Dust irritates eyes.
Safety Profile
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.
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.
Carcinogenicity
The oral LD50 values were 3900 mg/kg for
rats and 5760 mg/kg for mice.
Shipping
UN3077 Environmentally hazardous substances,
solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous
material, Technical Name Required.
Purification Methods
Crystallise it from water at room temperature (1mL/g) by adding EtOH and cooling. [Sisler & Audrieth Inorg Synth II 180 1946.]
Incompatibilities
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.
Check Digit Verification of cas no
The CAS Registry Mumber 7773-06-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,7 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7773-06:
(6*7)+(5*7)+(4*7)+(3*3)+(2*0)+(1*6)=120
120 % 10 = 0
So 7773-06-0 is a valid CAS Registry Number.
