(1742 – 1806)

(Born: Issoudun, France, 1742; Died: St. Denis, France, 10 January 1806) French chemist.

French chimist which developed a process preparation of the sodium carbonate which bears its name.E N 1780, Nicolas Leblanc became surgeon on behalf of the duke of Orleans. It is in 1786, thanks to its work on the crystallization, which it became famous. In 1789, it discovered a method of preparation of the sodium carbonate (soda), and allowed the development of the mineral chemical industry. It opened in 1791, close to Saint-Denis, thanks to the financial support of the duke of Orleans, a factory using this new process. Ruined, it committed suicide in Saint-Denis, in 1806.Leblanc became interested in the large-scale manufacture of soda because of the offer of a prize. He developed a process for making soda ash (sodium carbonate) from common salt, making possible the large-scale manufacture of glass, soap, paper, and other chemicals. The factory he set up with others was confiscated during the French Revolution, and he later committed suicide.
