Quality standards: GB/T534-2014 Proportion：1.84（98%：20℃）
Physical properties：It is a colourless, transparent and oily liquid. The boiling point and crystallization temperature vary with the content of sulphuric acid. When the content is 98%, the crystallization temperature is 0.1 ℃, and the boiling point is 332.4 ℃ (0.1 MPa). Sulfuric acid is soluble in water and emits a lot of heat. Concentrated sulphuric acid has strong water absorption and can be used as a desiccant.
Chemical Properties: Sulfuric acid is a strong acid, which can neutralize with alkali, react with metal oxides, many metals. Concentrated sulfuric acid has strong dehydration, and has a strong destructive effect on organic substances and human skin.
Uses: Sulfuric acid is widely used in chemical fertilizers, synthetic fibers, coatings, detergents, refrigerants, feed additives and petroleum, iron and steel, medicine and chemical industries.
Packaging, Storage and Transportation: Concentrated sulfuric acid has little corrosiveness to iron equipment, so it is shipped in iron tankers or barrels. Dilute sulfuric acid corrodes metal seriously, so it is packed in rubber-lined steel or plastic containers.
