for receiving different mineral acids and salts;
in production of chemical fibers, dyes, smoke - generating and explosive substances;
in oil, metalworking, textile, tanning, etc. industries;
in the food industry — it is registered as food additive of E513 (emulsifier);
in industrial organic synthesis in reactions:
dehydrations (receiving diethyl ether, esters);
hydrations (ethanol from ethylene);
sulphonations (synthetic detergents and intermediate products in production of dyes);
alkylations (receiving isooctane, polyethyleneglycol, caprolactam), etc.
For recovery of pitches in filters on production of distilled water.
World production of sulphuric acid apprx. 160 million tons per year. The largest consumer of sulphuric acid — production of mineral fertilizers. On 1 t of P₂O ₅ phosphoric fertilizers 2,2 - 3,4 t of sulphuric acid, and are spent for 1 t (NH ₄) ₂ by SO ₄ — 0,75 t of sulphuric acid. Therefore vitriol plants aim to build in complex with plants on production of mineral fertilizers.
