Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO 3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade, which is more stable in storage, is the usual form of what is described as "concentrated sulfuric acid".
Among the most important of his early achievements in this field was the introduction, in 1746, of leaden condensing chambers for the manufacture of sulfuric acid. [ 1 ] [ 2 ] Together with Samuel Garbett , in 1749 he built a factory at Prestonpans , in Scotland, for the production of the acid , and for some years they enjoyed a monopoly.
1746: The lead chamber process, for producing sulfuric acid in large quantities, invented by John Roebuck (1718–1794). c. 1760-c. 1840: Pioneers of the Industrial Revolution – Isambard Kingdom Brunel (1806–1859); Abraham Darby I (1678–1717); Abraham Darby II (1711–1763); Abraham Darby III (1750–1789); Robert Forester Mushet (1811 ...
1650 – Turquet de Mayerne obtains a gas or "inflammable air" by the action of dilute sulphuric acid on iron. 1662 – Boyle's law (gas law relating pressure and volume). 1670 – Robert Boyle produces hydrogen by reacting metals with acid. 1672 – "New Experiments touching the Relation between Flame and Air" by Robert Boyle.
This was the first practical production of sulphuric acid on a large scale. [12] Ward was in many ways quite generous to those living in poverty. He opened hospitals for the poor in Westminster and the City of London, and the clinics did not charge people for their service. It is estimated that he gave around the sum of £3,000 to charity.
He was instrumental in building the chemical supply business in the U.S. The specialty materials business of Honeywell traces its roots back to a small sulfuric acid company he started in 1870. Nichols was one of the original founders of the American Chemical Society, serving as president in 1918 and 1919.
The contact process is a method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum was originally used as the catalyst for this reaction; however, because it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium(V) oxide (V 2 O 5) has since been preferred.
In his Methods of Chemical Nomenclature (1787), Lavoisier invented the system of naming and classification still largely in use today, including names such as sulfuric acid, sulfates, and sulfites. In 1785, Berthollet was the first to introduce the use of chlorine gas as a commercial bleach.
