Product Description


Sulfamic Acid/Sulphamic Acid

Molecular Formula: NH2SO3H. Molecular weight:97.09

Sulfamic acid appears extra pure crystalline at normal temperatures. Its solution in water is a strong acid equivalent to hydrochloric acid and sulfuric acid. It’s known as solid sulfuric acid, non-volatile and non-hygroscopic. It decomposes at 205 ℃, the specific gravity is 2.126. The water solution of sulfamic acid is high ignitable substance; with its PH value is lower than that of formic acid, phosphoric acid and oxalic acid. 


Sulfamic acid, as a kind of important chemicals, is mainly used as a raw material to produce sweeteners Sodium Cyclamate and Acesulfame-k. It’s also widely used as herbicide, fireproofing agent, the cleaner of Ceramics and metals, soften agent and bleacher for paper and textile, catalyze for urea-formaldehyde, nitride remover in azoprotein dyestuff producing, stabilizer of chlorination and bleacher solution in the swimming pool. In analytical chemistry it can be used as primary reagent for the acid base titration.

(1). Sulfamic acid can be used for herbicide, fire retardant, paper and textile softener, metal cleaning agent;


(2). Sulfamic acid can be used for fireproof preparation, fabric and anti synthetic organic herbicides;


(3). Sulfamic acid can be used for fibers shrinkproof, bleaching, softening agent, cleaning agent, metal and ceramics, catalyst for the synthesis of urea formaldehyde resin.


(4). Sulfamic acid also can be used for the pickling of dyes and metal pickling, Bleaching auxiliaries.


(5). Sulfamic acid can reduce or eliminate the catalytic role of heavy metal ions in the drift, so that the quality of bleach can be guaranteed, and can reduce the oxidation and degradation of metal ions on the fiber.


(6). Sulfamic acid can prevent the peeling reaction of the fiber, improve the strength of the pulp, whiteness.

Attention can not be put into the use of floating liquid, and the first dissolved in water and then into the bleach.


(7). In the swimming pool, Sulfamic acid can be used for chlorination and bleaching of the stabilizer, etc..

Reference reagent for acid base titration in analytical chemistry.
