Sulfuric Acid 98%
Sulfuric acid is an inorganic compound with the formula H2SO4 and is the most important oxygenated acid of sulfur. Pure sulfuric acid is a colorless oily liquid, crystallized at 10.36 ° C, and its various aqueous solutions of different concentrations are usually used, which are obtained by tower method and contact method. The former is crude dilute sulfuric acid, the mass fraction is generally about 75%; The latter produces concentrated sulfuric acid with a mass fraction of 98.3%, a boiling point of 338℃ and a relative density of 1.84.
Sulfuric acid is a strong inorganic acid that can react with most metals. High concentration of sulfuric acid has a strong water absorption, can be used as a dehydrating agent, carbonizing wood, paper, cotton and linen fabrics and biological flesh and other carbohydrate-containing substances. When mixed with water, a large amount of heat energy is also released. It has strong corrosive and oxidizing properties, so it needs to be used with caution. It is an important industrial raw material, which can be used in the manufacture of fertilizers, drugs, explosives, pigments, detergents, batteries, etc., and is also widely used in the industry of purifying petroleum, metal smelting and dyes. It is commonly used as a chemical reagent and can be used as a dehydrating agent and sulfonating agent in organic synthesis.
