Application:
Tetramethylammonium Hydroxide Pentahydrate (CAS: 10424-65-4) (generally contains 3 or 5 crystal waters in each molecular). Easily deliquesces and absorbs carbon dioxide in air. Decomposed into methanol and trimethylamine at 130℃. Normally made 10%, 25% solution in water and crystalline. Strong organo-alkali. A supporting electrolyte in polarography, a developer for photoresists, and no residue catalyst in organosilicon polymerization processes. Tetramethylammonium Hydroxide Pentahydrate is organic base, it has very wide range of uses in the field of industrial research. Domestic tetramethylammonium hydroxide is mainly used as organic silicon products, such as the catalyst of synthesizing silicone oil, silicone rubber, silicone resin, although the amount is not big, but the yield and quality of the product is greatly affected. Foreign tetramethylammonium hydroxide is mainly used for polyester-based polymers, textiles, plastics, food, leather, wood processing, electroplating, and other microorganisms. At present, this product has came into the advanced technology areas, such as in printed circuit board manufacturing and microscopic sheets, it can be used as cleaning agent in integrated circuit and anisotropic etchant in semiconductor microfabrication technology of the Si-SiO2 interface. With the development of science and technology, the requirement of this type of chemical is increasing, the quality and quantity of tetramethylammonium hydroxide have put forward higher requirements. It can be used as additive of silicone rubber, methyl silicone oil and polarographic analysis reagents. In terms of organosilicone, it can be used as catalyst of dimethyl silicone oil, phenylmethyl silicone oil, a silicone oil diffusion pump, solvent-free silicone molding compound, silicone resin, silicone rubber or the like. In the analysis, it can be used as polarography agent, in the purification of the product it can be used as non-gray base to precipitate many metal elements, it can be used as silicon computer face brightener, cleaning agents and the like engraved touch in the production of organic silicon. The advantage of tetramethylammonium hydroxide as catalyst is that after the reaction when heat, it can decompose into gas and disappear, and it does not remain in the product.Sufficient Capacity: Sufficient facilities and technicians
