Ammonium sulfamate Chemical Properties,Usage,Production

Description

Ammonium sulfamate (or ammonium sulphamate) 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.

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.

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.

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.

Fire Hazard

Special Hazards of Combustion Products: Toxic oxides of nitrogen may form in fires.

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.
