Technical sulphuric acid is a colourless liquid with no smell. It violently dissolves in water releasing large amounts of heat. Sulphuric acid has so high affinity to water, that is a good dehydrating agent. Sulphuric acid is produced through a contact process by sulphur dioxide oxidation in air in the presence of vanadium catalyst to sulphur trioxide through its absorption in water or diluted sulphuric acid. Sulphuric acid is a highly caustic liquid causing dangerous and difficult to heal burns.
Used in the chemical, pharmaceutical, plastics and agricultural industries. Used in the production of inorganic and organic chemical compounds including fertilizers; catalytic processes; pH adjustment; as a dehydrating agent; in mineral and ore extraction and processing; surface etching and cleaning; electrolytic processes; gas production and absorption processes; production cells containing sulphuric acid; as a chemical reagent; for industrial cleaning.
Technical sulphuric acid Kt I should be stored in tanks or cisterns or specially adapted containers, in conditions which protect the product from freezing. Storage room temperature should be above 50C.
