2024年12月6日 · Sulfuric acid, dense, colorless, oily, corrosive liquid; one of the most important of all chemicals, prepared industrially by the reaction of water with sulfur trioxide. In one of its most familiar applications, sulfuric acid serves as the electrolyte in lead-acid storage batteries.
More sulphuric acid is produced than any other chemical in the world. In Western Europe in 1997 over 19 million tonnes were produced, the total production world-wide being estimated at around 150 million tonnes. About half of this output is produced in North America, Western Europe and Japan [20], [21].

sulfuric acid: Production of Sulfuric Acid | Infoplease
There are two major processes (lead chamber and contact) for production of sulfuric acid, and it is available commercially in a number of grades and concentrations. The lead chamber process, the older of the two processes, is used to produce much of the acid used to make fertilizers; it produces a relatively dilute acid (62%–78% H 2 SO 4 ).
