The company was founded as Nihon Soda Kogyo Co., Ltd., a producer of soda ash in 1918 by Katsujiro Iwai. It changed name in 1936 to Tokuyama Soda Co., Ltd. and in 1994 to its present name. [4] It is listed on the Tokyo Stock Exchange and is a component of the Nikkei 225 stock index. [5]
Solvay Process Company office building around 1889. The Solvay Process Company was a joint venture between Belgian chemists Ernest and Alfred Solvay, who owned the patent rights to the Solvay process, and Americans William B. Cogswell and Rowland Hazard II.
The Solvay process or ammonia–soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3). The ammonia–soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. [ 1 ]
American Natural Soda Ash Corporation (ANSAC) operates as the international distribution arm for three US manufacturers of natural soda ash produced from trona [1] deposits in Green River, Wyoming, the trade name for sodium carbonate Na 2 CO 3, is an essential raw material used in the manufacture of glass, detergents, and several sodium-based chemicals.
The British and Kenyan soda ash businesses of ICI were segregated from the rest of the ICI in 1991 and then demerged from ICI as Brunner Mond Holdings Limited. In 1998, this company acquired the soda ash production capabilities of Akzo Nobel in The Netherlands to form Brunner Mond B.V. [ 6 ]
The Leblanc process was an early industrial process for making soda ash (sodium carbonate) used throughout the 19th century, named after its inventor, Nicolas Leblanc.It involved two stages: making sodium sulfate from sodium chloride, followed by reacting the sodium sulfate with coal and calcium carbonate to make sodium carbonate.
The soda ash plant used salt from the St Kilda lagoons which was (normally) harvested in autumn and piped as a saturated brine solution under the Port River to the plant, and limestone from its Angaston quarry was transported to the plant by the Penrice Stone Train. Using ammonia, these raw materials were converted to soda ash by the Solvay ...
Barium carbonate is made commercially from barium sulfide by treatment with sodium carbonate at 60 to 70 °C (soda ash method) or, more commonly carbon dioxide at 40 to 90 °C: In the soda ash process, an aqueous solution of barium sulfide is treated with sodium carbonate: [5] BaS + H 2 O + CO 2 → BaCO 3 + H 2 S
