Sulfamic acid

CAS number : 5329-14-6

Molecular weight :97.09

Molecular formula/chemical symbol :NH2SO3H

Description :

Apearances: White powder, at room temperature, kept dry in contact with water, the amino acid of the solid non-hygroscopic, is relatively stable. An aqueous solution of sulfamic acid having the same strongly acidic with hydrochloric acid, sulfuric acid, etc., and therefore alias known as solid sulfuric acid, it has a non-volatile, no odor and minimal toxicity to the human body Apearanceistics. The aqueous solution of sulfamic acid is slower effect of iron corrosion products, can be added some sodium chloride, so that to produce hydrochloric slowly, thereby effectively dissolved iron scale. An aqueous solution of sulfamic acid to remove surface scale and corrosion of materials such as iron, steel, copper, stainless steel equipment manufactured product. Further, it is the only can be used as the acid cleaning of the surface of the galvanized metal. Cleaning using an aqueous solution of sulfamic acid, the temperature control in general does not exceed 66 ° C (in case of the amino sulfonic acid decomposition), the concentration does not exceed 10%.

USES :

Ammonia is a sulfonic acid is an important fine chemical products widely used in a variety of industrial equipment for metal and ceramic manufacturing and commercial cleaning agents, oil and processing and cleaning agent, the electroplating industrial agent electrochemical polishing agent, asphalt emulsifier etching agent, dyes, pharmaceuticals and pigments industrial sulfonating agent, dyeing agent, effective bleaching agents, fibers, paper with flame retardants, softeners, resins, crosslinking accelerators, herbicides, anti-cumyl agents and standard analytical reagents. fields. Simple the sulfamate production process, the reaction is easier to control, raw materials and equipment are relatively easy to solve, the wastewater can be handled easily by-products can be used effectively. The product can be used instead of sulfuric acid, packaging, storage, transportation is very convenient.
