Sulfuric acid is an inorganic compound with the chemical formula H2SO4, the most important oxyacid of sulfur. Pure sulfuric acid is a colorless oily liquid that crystallizes at 10.36°C. Its aqueous solutions of various concentrations are usually used and prepared by tower method and contact method. The former is crude dilute sulfuric acid, with a mass fraction of about 75%; the latter can be obtained with a mass fraction of 98.3% concentrated sulfuric acid, with a boiling point of 338°C and a relative density of 1.84.
Sulfuric acid is the most active binary inorganic strong acid, which can react with most 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 flesh. When mixed with water, it will release a lot of heat energy. It is highly corrosive and oxidizing and should be used with caution. It is an important industrial raw material, which can be used to manufacture fertilizers, medicines, explosives, pigments, detergents, batteries, etc., and is also widely used in industries such as purification of petroleum, metal smelting, and dyes. It is often used as a chemical reagent, and can be used as a dehydrating agent and a sulfonating agent in organic synthesis.
Sulfuric acid or sulphuric acid, known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula H₂SO₄. It is a colorless, odorless, and viscous liquid that is miscible with water.
Package:
Sulfuric acid is usually packaged in plastic drums or glass bottles, each with a capacity of 25 liters or 50 liters. During transportation, sulfuric acid should avoid mixing with other substances, and avoid high temperature and direct sunlight exposure. The transportation of sulfuric acid should comply with relevant national regulations and standards.
