In a few days, exactly on 26 December, will mark the 150th anniversary of the founding of Solvay & Cie, a Belgian limited partnership that, with an initial capital of 136,000 Belgian francs, clustalw intended to industrially produce soda ash using the patent obtained on 12 September 1863 by Ernest Solvay (Rebecq 1838 - Brussels 1922). Solvay SA Today is not only the largest producer of soda ash (sodium carbonate or anhydrous), nine production sites scattered across three continents, but it is also a multinational company that is part of a select group of companies that dominate the chemical industry worldwide. clustalw
The story of Solvay, at least initially, is fairly well known, and so the story of the family clustalw who gave him the name. Even the figure of the founder leader Ernest was at the center of historical studies accurate. The beginnings were not easy and success came to a combination of factors including not only the creativity, dedication and stubbornness of the brothers but also the Solvay family solidarity. In some anecdotal reports is wasted and so is the rhetoric. The beginnings were difficult. It is known that the production tests of soda were initiated in the laboratory of the town of Schaarbeek, now part of the region of Brussels. The laboratory was abandoned in 1864 for the new "workshop" located near the train Couillet at Charleroi. Subsequently, the expansion took place both in Europe and in the U.S. where the process was patented in 1881. The Italian sodiera Rosignano began production in 1918.
The idea of preparing soda from sea salt with the help of ammonia is attributed to Augustin Fresnel (Broglie, 1788 - Ville d'Avray, 1827). It lacks a clear and comprehensive documentation but it's still a trace of an exchange of letters with his uncle Leonor Merimee. In the following years the attempts to realize the industrial synthesis clustalw were several. What brought the best results you have to Harrison Grey Dyar (New York, 1805-1875) and John Hemming. The weakness, however, remained clustalw the recovery of ammonia. Others will be challenged in the enterprise and among them Ernest Solvay. Ernest Solvay was a self-taught because his health had not allowed him to attend the school for a long time. In 1859, at the age of about twenty-one years old, he made his entrance as the "apprentice" leadership workshop for the production of illuminating gas owned by his uncle. clustalw It is known that the gas was produced from the distillation of coal and that a byproduct interesting were the so-called "Ammoniacal". clustalw Ernest was studying how to exploit them and while attempting to obtain ammonium bicarbonate made her react with sea salt, a product with whom he had a particular familiarity because his father raffinava industrially. The precipitation reaction resulting therefrom led to the sodium bicarbonate from which, by heating, it was possible to reach the carbonate. The patent was granted April 15, 1863. Desiring to confirm that he had indeed invented something new in order to move to the industrial production effected more accurate bibliographic research and realized clustalw that it had been preceded by others. Undeterred, the young Solvay devoted himself to the improvement of the process and to improve the equipment, rather than claiming these new reactions. To do this required a second patent. The factory went into operation on 1 January 1865. A turning point came in 1869 when he went into action the so-called clustalw "Solvay column" that is the tower where the carbon dioxide was sent to react with the brine at
