	Nicolas Leblanc Summary
		The Leblanc process was crucial to industrial-chemical progress in the nineteenth century, as economical supplies of soda ash were necessary for the widespread manufacture of both soap and glass.
		Leblanc was unable to raise the necessary capital, and the settlement of his claims against the French government in 1805 was much less than he had hoped for.
		The prize was awarded to Nicolas Leblanc for a process which used sea salt and sulfuric acid as the raw materials.

	The Ammonia Soda Process
		In the ease of the Leblanc process, this expenditure of fuel is large, and is chiefly used in carrying out the reactions in the salt-cake and the fl-ash furnaces.
		In the ammonia process the principal reactions are exothermic, but some fuel is consumed by the calcination of the precipitated bicarbonate and in the preparation of the quicklime used in the ammonia recovery and for generating carbon dioxide.
		Although less fuel is used than in the Leblanc process, the practical economy of the ammonia process is not so great as would at first appear; for all the chlorine is lost, together with a large part of the original salt used.

	Baking Soda: How Products are Made
		Named after Nicolas Leblanc, the French chemist who invented it, the Leblanc process was the earliest means of manufacturing soda ash (Na), from which sodium bicarbonate is made.
		In the Solvay process, carbon dioxide and ammonia are passed into a concentrated solution of sodium chloride.
		The theoretical yield from the process, according to the Church and Dwight Company, is between 90 and 95 percent, and the baking soda manufactured is more than 99 percent pure.

	ALKALI MANUFACTURE - Online Information article about ALKALI MANUFACTURE
		Nicolas Leblanc (q.v.) about 1790, begins with the decomposition of sodium chloride by sulphuric acid, by which sodium sulphate and hydrochloric acid are produced.
		Weldon's later attempts at superseding his classical process by other inventions which utilize a larger proportion of the chlorine, introduced as hydrochloric acid, have not been successful in the long run, although some of them were aided by the great technical skill of A.
		process, by employing the active oxygen of manganese dioxide to convert hydrochloric acid into free chlorine, and he employed the atmospheric oxygen only indirectly, for the recovery of manganese dioxide from the manganese chloride formed.

	SODA,
		The Leblanc process was superseded by the less expensive Solvay process, invented by the Belgian chemist Ernest Solvay, in an attempt to utilize the ammonia obtained as a by-product in the coke industry.
		In the Solvay process sodium chloride is treated with ammonia gas and then with carbon dioxide, resulting in the formation of sodium bicarbonate, NaHCO3, and ammonium chloride.
		The compound is used medicinally to neutralize excessive acid in the stomach and industrially to moderate the alkalinity of sodium carbonate.

	Industrial Chemistry, Inorganic - The chemical industry, Sources of inorganic raw materials
		The introduction of the Leblanc process in the northwest of England led to a general public outcry against the dark and corrosive smoke that covered the surrounding countryside.
		The Solvay process had enormous advantages over the Leblanc process: It did not generate as much waste and pollution; its raw materials, brine and ammonia, were readily available (the latter from gasworks); less fuel was used, and no sulfur or nitrate was involved.
		In the Solvay process, calcium carbonate and sodium chloride are used to produce calcium chloride and sodium carbonate with ammonia (which is recycled) as a medium for dissolving and carbonating the sodium chloride and calcium hydroxide for precipitating calcium chloride from the solution.

		These vessels, as well as all others which are used in the process, are not open to the air, but communicate with it through washers in which fresh salt solution is employed for retaining any escaping vapours of ammonia.
		Diaphragm process is probably the only one employed at present for the decomposition of potassium chloride, and it is also used for sodium chloride.
		The latter dissolves the sodium as it is formed and carries it to an outer compartment where by the action of water the sodium is converted into caustic soda, while the lead returns to the inner compartment.

	sulfuric acid. The Columbia Encyclopedia, Sixth Edition. 2001-05
		In both processes sulfur dioxide is oxidized and dissolved in water.
		A process for its synthesis by burning sulfur with saltpeter (potassium nitrate) was first used by Johann Glauber in the 17th cent.
		The contact process was originally developed c.1830 by Peregrine Phillips in England; it was little used until a need for concentrated acid arose, particularly for the manufacture of synthetic organic dyes.

		In the fall, the stalks stand 7' to 10' tall and grow 1" to 1-1/2" in diameter, it is cut and transported to mills where it is piled in great heaps awaiting the grinding process.

		Croll's process, however, we get an increased yield of salts on the acid used, as follows: The experiments were made with sulphuric acid of the specific gravity of 1838, or nearly concentrated oil of vitriol; and the quantity used was 8 ounces in each experiment.

	Leblanc, Nicolas (Site not responding. Last check: )
		In the Leblanc process, salt was first converted into sodium sulphate by the action of sulphuric acid, which was then roasted with chalk or limestone (calcium carbonate) and coal to produce a mixture of sodium carbonate and sulphide.
		Leblanc devised his method of producing soda ash to win a prize offered 1775 by the French Academy of Sciences, but the Revolutionary government granted him only a patent (1791), which they seized along with his factory three years later.
		He had no money left to re-establish the process when the factory was handed back to him by Napoleon in 1802.

	Soap - its earthly origin
		Until the "continuous process" began being used in the 1930's, the "kettle process," or "boiling process" enabled by development of the Leblanc process in 1791, for creating sodium hyroxide, was used.
		The answer is that it comes from the same industrially-produced (by the Haber process) synthetic ammonia that is used in producing the sodium hydroxide (via the Solvey process) that is used in soap making, and that is used as a source of plant-food nitrogen.
		That is, once fats are split into fatty acids and glycerine (using zinc soap made from previous batches of fatty acids), ammonia is used both to (1) create the sodium hydroxide that is used to produce soap from the fatty acids, and (2) to create explosives from the glycerine.

	It was all about alkali
		The process that bore his name, however, would provide the basis for the development of the world’s industrial chemical industry, becoming the most important method of producing chemicals for almost a century.
		Leblanc was forced to disclose all the details of his patented process to the government, which published them for anyone to use.
		A modified version of the Leblanc process was used on a small scale, however, to prepare alkali from sodium sulfate mined in Wyoming.

	Soda ash, Solvay style
		Within 20 years after the Leblanc process had been introduced in 1791, the goal of finding a better way to make soda ash began to attract the interest of chemists.
		The heart of his process was a cylindrical iron-carbonizing tower in which rising carbon dioxide mixes with a spray of ammonia brine.
		Later, Mond developed a process for refining nickel ores by treating them with carbon monoxide to form nickel carbonyl, which is easily decomposed to pure nickel.

	Handmade Soap, Secret Wimmins Business
		The Leblanc process yielded quantities of good quality, inexpensive soda ash.
		Also important to the advancement of soap technology was the mid-1800s invention by the Belgian chemist, Ernest Solvay, of the ammonia process, which also used common table salt, or sodium chloride, to make soda ash.
		Solvay's process further reduced the cost of obtaining this alkali, and increased both the quality and quantity of the soda ash available for manufacturing soap.
