Sodium methoxide applied in Medicine

Posted in General | 11:34

Sodium methoxide also known as alcoholate, methoxide and sodium methylate. It is a versatile chemical reagent used for many decades in various industries to produce high-value end products like pharmaceuticals, food ingredients, pigments and crop protecting agents. Sodium methoxide is a routinely used base in organic chemistry, applicable to the synthesis of numerous compounds, ranging from pharmaceuticals to agrichemicals. Sodium Methoxide is mainly used for condensation agent, strong alkaline catalyst, and methoxy agent. It also applied in producing drugs such as vitamin B1 and A, sulfadiazine and minor uses of pesticides production. Xiangbang Sodium Methoxide Co.Ltd is one of the largest domestic manufacturers of sodium methoxide and sodium methylate solution in China, Our company is one of the "National New & High Technological Enterprises" and "Backbone Enterprises of Fine and Special Chemicals Industrial Base", one of the National Torch Projects.

Hazards of Methylparaben

Posted in General | 14:07

Methylparaben and propylparaben are considered generally recognized as safe (GRAS) for food and cosmetic antibacterial preservation, for example, dairy products, pickles, beverage, fruit juice/jelly and confectionery. It does not appear to be irritating when used topically, although some people may show cross-sensitivity in people allergic to local anesthetics that are metabolized to para-aminobenzoic acid. Cases of local contact dermatitis have been reported. All parabens have similar structure to estrogen. Studies conducted in the early 2000s located traces of parabens in breast tumors, but evidence has not linked parabens with breast cancer. Nanjing Jiancheng Chemical Industrial Co.Ltd founded in 1998, is one of the largest preservative manufacture in China. The Factory mainly produces all kinds of preservatives, which widely applied in cosmetics, medicine, and food industry. Our main products are Diazolidinyl urea, Imidazolidinyl urea, Methylparaben, Ethylparaben, Propylparaben, Butylparaben, Bronopol, Allantoin, Germall Plus, JMB, JMC, JMBP and so on. Our products are well exported to all over the world, such as North America, Europe and Southeast Asia. Contact Us Add: LI Shui Economic and Technological Development Area, Nanjing, Jiangsu.

Chemical reaction of Sodium Sulphite

Posted in General | 09:57

Sodium sulphite forms a bisulfite adduct with aldehydes, and with ketones forms a sulfonic acid. It is used to purify or isolate aldehydes and ketones. Sulfite oxidation of sulfur in +4, which could rise or lower, so the sulfurous acid root there are both oxidizing and reducing Sodium sulfite is easily weathered and oxidized to sulfate in air.And it will lose crystal water at 150 degrees. Reheat melting as a mixture of sodium sulfide and sodium sulfate. Sodium Sulphite is also used as a preservative to prevent dried fruit from discoloring, and for preserving meats, and is used in the same way as sodium thiosulfate to convert elemental halogens to their respective hydrohalic acids. Established in 1954, Kaixiang Chemical Factory specializes in producing Sodium Bicarbonate, sodium metabisulphite. Manufacturing equipment of Sodium Bicarbonate ,sodium metabisulphite,caustic soda, caustic soda flakes, Sodium Thiosulphate, sodium Thiosulfate Pentahydrate ,Sodium Bisulfite, Sodium Sulfite has experienced four big reforms and manufacturing technique has experienced many technical innovations.

An introduction to Sodium thiosulfate

Posted in General | 09:38

Sodium thiosulfate is a colorless, crystalline solid with a melting point of 48 degrees C. It is freely soluble in water. In analytical chemistry, sodium thiosulfate is used for the determination of the strength of a given solution of iodine. Sodium thiosulfate is preferred in iodometric analysis due to the fact that sodium thiosulfate is oxidized by iodine. It is also used to determine the strength of many oxidizing agents, such potassium dichromate, potassium permanganate and copper sulfate, which, on reacting with excess KI (potassium iodide) solution, liberate iodine. The liberated iodine is titrated with a standard solution of sodium thiosulfate. Established in 1954, Kaixiang Chemical Factory specializes in producing Sodium Bicarbonate, sodium metabisulphite. Manufacturing equipment of Sodium Bicarbonate ,sodium metabisulphite,caustic soda, caustic soda flakes, Sodium Thiosulphate, sodium Thiosulfate Pentahydrate ,Sodium Bisulfite, Sodium Sulfite has experienced four big reforms and manufacturing technique has experienced many technical innovations.

Use of Tungsten trioxide

Posted in General | 14:50

Tungsten trioxide is mainly used for making reduction of tungsten powder and tungsten carbide powder, and its also used in the production of cemented carbide products, such as tool and die manufacturing. Generally Tungsten trioxide is used in industry to manufacture tungstates for xray screen phosphors, for fireproofing fabrics and in gas sensors. Due to its rich yellow color, Tungsten trioxide is also used as a pigment in ceramics and paints. In recent years, tungsten trioxide has been employed in the production of electrochromic windows, or smart windows. These windows are electrically switchable glass that change light transmission properties with an applied voltage. This allows the user to tint their windows, changing the amount of heat or light passing through. Bouling Chemical Co., Limited was founded in 1988 and it is a national advanced and new technical enterprise so it's the only one standard enterprise which produce the series products of Vanadium Pentoxide including vanadium pentoxide 98% , vanadium pentoxide 99.5%, vanadium pentoxide 99.7%, vanadium pentoxide 99%,vanadium pentoxide 99.9%, Vanadium Pentoxide Flake, tungsten and molybdenum including sodium molybdate, Barium Molybdate, Ammonium Dimolybdate, Ammonium Tetramolybdate, Ammonium Heptamolybdate, molybdenum disulfide, molybdenum trioxide, Ammonium Molybdate in Anhui province.
