Sulfuric acid for industrial use in various industrial sectors are widely used, mainly fertilizer industry, metallurgical industry, petroleum industry, machinery industry, pharmaceutical industry, production of detergents, military industry, nuclear industry and the aerospace industry. Also used in the production of dyes, pesticides, chemical fiber, plastics, coatings, and a variety of basic organic and inorganic chemical products. Early sulfuric acid industry have adopted nitration, low intensity of production equipment, product concentration only 60 to 76%. Since the 20th century, gradually replaced by nitration contact method. Production of sulfuric acid raw materials are sulfur, pyrite, non-ferrous metal smelting smoke, gypsum, hydrogen sulfide, sulfur dioxide and sulfuric acid and other waste. Sulfur, pyrite and smelt smoke are three main ingredients. Sulfuric acid: sulfuric acid (chemical formula?? H SO), sulfur oxyacid most important. Anhydrous sulfuric acid is a colorless, oily liquid sulfuric acid corrosion, 10.36 ℃ crystallization, usually using aqueous solutions of different concentrations of it, taking the contact with the tower law and the rule of law. Former income as a crude sulfuric acid, mass fraction is generally about 75%; the latter can be obtained 98.3% of the mass fraction of pure concentrated sulfuric acid, boiling point 338 ℃, relative density of 1.84. Sulfuric acid is one of the most active agricultural use binary inorganic acid and sulfuric acid, the reaction can occur and many metals. High concentrations of sulfuric acid has strong water absorption, can be used as a dehydrating agent, carbonized wood, paper, cotton and linen fabrics and biological flesh and other carbohydrate-containing substances. Sulfuric acid when mixed with water industrial risks, will release a lot of heat. It has a strong resistance and oxidation resistance, so use it with caution. Is an important industrial raw material, can be used to manufacture fertilizers, drugs, explosives, paints, detergents, batteries, etc., are also widely used in the purification of oil, metal smelting and other industrial dyes. Commonly used as a chemical reagent, it can be used as a dehydrating agent and sulfonating agent in organic synthesis.
