Uses as the major chemical raw material of the production of caustic soda, soda ash, widely used in alkali industry. As a semiconductor silicon doping source, it can be used for preparation of high purity boron and organic boron compound. Trona is mainly used for making soda ash, caustic soda, soda, and other products. Soda ash is an important industrial raw material, widely used in glass, chemicals, light industry, textile, dyeing, metallurgy, petroleum processing, pharmaceuticals, food and so on. Caustic soda is mainly used for rayon, paper, dyes, soap, plastics, pharmaceuticals, agricultural chemicals and so on. Baking soda is mainly used in food, plastics, rubber, pharmaceutical, printing and dyeing, tanning, soaking seeds and other areas. As a dopant materials of semiconductor, catalyst, intermediate and brominated agent of organic synthesis, It is a raw material for producing high purity boron and other organic boron compound. Used in organic synthesis and preparation for high purity boron. As catalyst, intermediates and Brominating agents for organic synthesis, raw materials for manufacturing high purity boron and other organic boron compound. Boron Tribromide is used as a reagent in the synthesis of 8-hydroxyquinolato compounds used as electron transport materials in EL devices. It is also used in the demethylation of aryl methyl ethers by boron tribromide. manufacture of diborane; ultra high purity boron. Reagent for cleavage of ethers, amines, thiols; addition of allenes and alkynes. Catalyst in manufacture of diborane, ultrahigh-purity boron, and semiconductors
Production method Direct synthesis is putting the dried powder of boron into the reaction tube of a tubular reactor, to make the reaction can be carried out sufficiently, a certain amount of filler should be placed in the reaction tube, the filler material is the same as the inner wall of the reaction tube. The reaction tube was heated to 850 ℃, also bromine in the bromine vessel was heated to a boil, then poured into reaction tube. The boron tribromide liquid produced with activated carbon, zinc and aluminum scrap together in debromination vessel heated to reflux until boron bromide produced is a colorless, and then by crude distillation, distillation, obtained completely colorless bromide boron products. 2B + 3Br2 → 2BBr3 Salt Lake alkaline mineral general uses open-pit mining, ancient alkaline mineral general uses underground dissolution mining law. Mining process 1. open-pit mining 2. underground dissolution method
