98%sulfuric acid
Product Introduction:
Sulfuric acid(chemical formula:H?SO?)is the most important oxygen-containing acid of sulfur.Anhydrous sulfuric acid is a colorless oily liquid that crystallizes at 10.36¡æ.Various concentrations of its aqueous solution are commonly used to prepare it using tower and contact methods.The former produces crude dilute sulfuric acid,with a mass fraction generally around 75%;The latter can obtain pure concentrated sulfuric acid with a mass fraction of 98.3%,boiling point of 338¡æ,and relative density of 1.84.
Sulfuric acid is the most reactive binary inorganic strong acid that can react with many 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.When mixed with water,a large amount of heat energy is also released.It has strong corrosiveness and oxidizing properties,so it should be used with caution.It is an important industrial raw material that can be used to manufacture fertilizers,drugs,pigments,detergents,batteries,etc.It is also widely used in industries such as petroleum purification,metal smelting,and dyes.Commonly used as a chemical reagent,it can be used as a dehydrating agent and sulfonating agent in organic synthesis.
