Details

Sulfuric acid is an inorganic compound with the chemical formula H2SO4, which is the most important oxygen-containing acid of sulfur. Pure sulfuric acid is a colorless oily liquid. Sulfuric acid is the most active binary inorganic strong acid that can react with the vast majority of metals. High concentration sulfuric acid has strong water absorption and can be used as a dehydrating agent to carbonize carbohydrate containing substances such as wood, paper, cotton and linen fabrics, and biological skin and meat. When mixed with water, a large amount of heat energy is also released. It has strong corrosiveness and oxidation, so it needs to be used with caution. It is an important industrial raw material that can be used to manufacture fertilizers, drugs, explosives, pigments, detergents, batteries, etc. It is also widely used in industries such as purifying petroleum, metal smelting, and dyes. Commonly used as a chemical reagent, it can be used as a dehydrating agent and sulfonating agent in organic synthesis.

purpose
Laboratory important reagents, mainly used as analytical reagents and neutralizing agents. Widely used in hospitals, scientific research, universities, battery industry, electronics industry, pharmaceutical industry, etc.
Industrial use
Sulfuric acid is used in the metallurgical industry and metal processing, especially in the production process of non-ferrous metals. For the refining of certain precious metals, sulfuric acid is also required to dissolve and remove impurities from other metals. Before cold rolling, cold drawing, and stamping processes are carried out in the steel industry, sulfuric acid must be used to remove iron oxide from the surface of the steel. In rolling thin plates, cold drawn seamless steel pipes, and other steel products with high quality requirements, it is necessary to wash them with sulfuric acid every time they are rolled. In addition, welded steel pipes, thin iron sheets, iron wires, etc. must be pickled with sulfuric acid before galvanizing.
In the production process of petroleum products such as gasoline and lubricants in the petroleum industry, concentrated sulfuric acid refining is required to remove sulfur compounds and unsaturated hydrocarbons.
