Ammoniumsulfamaat

Ammoniumsulfamaat, or ammonium sulfamate, is the ammonium salt of sulfamic acid. It is a white to off-white crystalline solid that readily dissolves in water. The compound is typically prepared by neutralizing sulfamic acid with an ammonium base such as ammonium hydroxide or an ammonium salt.

Properties of ammoniumsulfamaat include its high water solubility, stability at room temperature, and sensitivity to strong oxidizers and heat. On heating, it can decompose, releasing volatile products such as ammonia and sulfur-containing oxides. It is commonly handled as a dry solid or as an aqueous solution in industrial settings.

Applications of ammoniumsulfamaat are varied. It has been used as a non-selective herbicide in some agricultural and horticultural contexts, where it aids in weed control. In chemical synthesis, it serves as a source of the sulfamate functional group for certain reactions and as an intermediate in various preparations. The regulatory status and acceptance of its uses vary by country and application.

Safety and handling guidelines emphasize that ammoniumsulfamaat can irritate the skin, eyes, and respiratory tract. Protective equipment such as gloves and eyewear should be used, and exposure should be minimized. It should be stored in a cool, dry place away from incompatible materials, particularly oxidizers. In case of spills, containment and proper disposal according to local regulations are advised. Environmentally, concentrated solutions can be toxic to aquatic life; degradation in soil and water depends on conditions and exposure levels.
