Product Description Product DescriptionSulfamic AcidCapacity: 90000 tons per yearMolecular Formula: H3NO3SMolecular Weight: 97.09CAS NO. 5329-14-6HS CODE: 2811199090--White orthorhombic crystal. Nonvolatile, nonhygroscopic, odorless. High stability at normal temperature and can maintain original quality for several years. Freely soluble in water and liquid ammonia, strongly acidic in water solution.--Slightly soluble in methanol, insoluble in ethanol and ether. Characteristics of double functional group of amidogen and sulphonic radical, may go on chemical reaction with many matters.--Melting point is 205oC, decomposing temperature is 209oC.ApplicationMainly used as cleaning agent of descaling, clearing away oxidize surface, slightly corrosive to metal. It can be used in water treatment sterilization, bleach fiber, wood and paper; Acidification process, removing nitrite in tobacco, sludge treatment in oil mines; Manufacturing of Dyes, Pigments; Fire retardant; Curing agent in plastic industry; Chlorine Stabilization; Electroplating and Electro-refining; Raw material for pesticide intermediate, ramification of sulfamic acid etc..White rhombic crystal system flake crystal, colorless, tasteless, odorless, non-volatile, non-hygroscopic, flammable, low toxicity. The property is very stable, stored at room temperature for many years without change. The relative density is 2.126, the specific gravity is 2.126, the melting point is 205oC, the decomposition begins at 209oC, and the decomposition at 260oC releases SO2, SO3, N2, water and other trace products. Refractive index α type 1.553, β type 1.563, γ type 1.568, dissociation constant 1.10×10-2, refraction coefficient (25±3oC) 1.553 ~ 1.568, heat of formation is 685.9kJ/mol. Soluble in water and liquid ammonia, the pH value of 1 aqueous solution is 1.18, the solubility in water at 0oC is 14.68g/100g water, and at 80oC is 47.08g/100g water. Slightly soluble in methanol, insoluble in ethanol and ether, insoluble in carbon disulfide and liquid sulfur dioxide. Sulfamic acid aqueous solution has the same strong acidity as sulfuric acid and hydrochloric acid. All common salts (except calcium, barium, and lead salts) are insoluble in water. It is soluble in formamide and insoluble in other organic solvents.Product ParametersTest itemsunitTest standardTest resultsAppearance-colorless or white crystalswhite crystalNH2SO3H%≥99.599.75SO42-%≤0.05<0.03Fe%≤0.0050.00034Water insoluble matter%≤0.020.003moisture%≤0.10.035Pb%≤0.001<0.001CHLORIDE(CL)%≤0.002<0.002AMMONIA%≤0.0002<0.0002 Test itemsunitTest standardTest resultsAppearance colorless or white crystalswhite crystalNH2SO3H%≥99.599.59SO42-%≤0.05<0.05Fe%≤0.0050.001Water Insoluble Matter%≤0.020.01Moisture%≤0.10.04Pb%≤0.001<0.001 Test itemsunitTest standardTest resultsAppearance Colorless or white crystallineWhite crystallineNH2SO3H%≥99.599.85Sulfate (SO42- )%≤0.05<0.02Lose on drying%≤0.10.01Fe%≤0.0050.0006(Pb)Heavy Metal%≤0.001<0.001Insoluble Water Substance%≤0.020.010 PH Value(1%) 1.0-1.41.2 Packaging & ShippingPacking: Knitting bags with plastic liners, Compound Kraft paper; PE bag, Valve Bags, Jumbo bag; 25kg, 500kg, 600kg, 750kg, 800kg, 1000kg per bag.Storage :Stored in dry and cool place.
