Sulfuric Acid Used in the Agriculture Industry
In the agricultural fertiliser sector, sulfuric acid is the largest consumer–used primarily in producing phosphoric acid and ammonium sulphate, for dissolving phosphate rock and supplying sulphur as a key nutrient.
Sulfuric Acid Used in the Metallurgical Industry
Sulfuric acid is used in leaching processes to extract metal ores, including copper, zinc, and aluminium. In metallurgy, it also serves as an oxidising agent and flux.
Sulfuric Acid Used in the Battery Industry
Sulfuric acid is used as battery electrolyte in lead-acid storage systems, typically at 30%–40% concentration.
Sulfuric Acid Used in the Pharmaceutical Industry
Sulfuric acid is used in the synthesis of antibiotics, sulfonamide pharmaceuticals, and vitamins.
Sulfuric Acid Used in the Electric Industry
High-purity sulfuric acid (electronic grade) is used in wafer cleaning, photoresist stripping, and etching, with extremely low metal ion content requirements (G1–G5 grades).
Sulfuric Acid Used in the Water Treatment Industry
Sulfuric acid is used in water treatment (pH adjustment and ion exchange resin regeneration), as well as in leather tanning and papermaking.
Sulfuric Acid Used in the Laboratory
Sulfuric acid is commonly used in laboratories as a dehydrating agent, drying agent, and sulfonating agent.
Sulfuric Acid Used in the Textile Industry
Sulfuric acid is used in the textile industry as a decolourising agent for dyes and fibres. It removes pigments and impurities from fibres, improving the effectiveness of dyeing and bleaching processes.
Sulfuric Acid Used in the Energy Industry
Sulfuric acid serves as a catalyst in the synthesis of fuel ethanol and butanol, promoting reactions and improving yield and purity.
Sulfuric Acid Used in the Food Industry
Sulfuric acid serves as an acidity‑adjusting agent and decolourising agent for food‑processing applications. It is utilised in the manufacturing of jellies, pickled goods and sauces for pH adjustment and colour removal during production.
Sulfuric Acid Used in the Metalworking Industry
Sulfuric acid is used as a pickling agent to remove dirt and oxides from metal surfaces. In electroplating, it also serves as a desalting agent to eliminate salt deposits on metal surfaces.
Sulfuric Acid Used in the Chemical Manufacturing Industry
Sulfuric acid is a key feedstock for producing other chemicals, such as ammonium sulphate, barium sulphate, and copper sulphate. It also serves as a reaction medium or reactant in synthesising compounds like sulphate esters and sulfonyl chlorides.
