Sodium-Methoxide

Characteristics of Sodium Methoxide

It is well-known that Sodium methoxide is a routinely used base in organic chemistry, applicable to the synthesis of numerous compounds, ranging from pharmaceuticals to agrichemicals.
Liquid Sodium methoxide can get high concentration of Sodium methoxide, low Free alkali , and it can remove the impurities of alcohol types. For this reason concentration of Na2CO3 in this method is lower than that of alkali method, it can get higher quality and yield.
Sodium methoxide in powder form is mainly used in pharmaceutical industry, such as the manufacture of Vitamin A1, Vitamin BI, Sulfamethoxypyridazine, Sulfadiazine, trimethoprim and so on. It also can be applied as edible catayst and analytical reagent.
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.
In the meantime, Xiangbang attaches great importance to the quality of products and services, and makes efforts to combine the technology and various resources effectively in order to improve the producing processes and the quality of products continuously, and to satisfy the demands of all users in every aspect.

Application field of diethyl malonate

Diethyl malonate is a colorless liquid with a sweet ether odor. It is a compound of the hydroxyl group in the two carboxyl groups of malonic acid, which is substituted by ethoxyl, and the molecular formula is CH2(COOC2H5)2. Diethyl malonate is influenced by two carbonyl groups and has high activity. It can produces sodium salt with sodium glycol, and then reacts with halogenated hydrocarbon to produce diethyl malonate, which is substituted for one or two alkyls.Diethyl malonate condensation reaction with carbonyl compounds, produce unsaturated compounds RCH = C (COOC2).Diethyl malonate can be used as raw material for medicine. Its other functions are as follows:
1.It is used as the intermediate of sulfonamide and barbiturate, as well as the intermediate of spices and dyes.
2. GB 2760 a 96 provides for the use of edible spices. Mainly used in the preparation of pear, apple, grape, cherry and other fruit flavors.
3. Diethyl malonate is an important intermediate for the preparation of 2-amino-4, 6-dimethoxypyrimidine, as well as the plasticizer 4 and diethyl malonate of nitric acid cellulose, which is an organic synthesis intermediate. Ethyl ester can be used for nitrification, and further the principle is to produce diethyl amine malonate, which is an important intermediate for synthesizing amino acids.
4. Check ammonia and potassium, for resin and nitrocellulose solvent, plasticizer.

Sodium methoxide’s preparing process

Sodium methoxide is a kind of alcohol salt produced by methanol. Its chemical formula is CH3ONa, which is a strong base commonly used in organic synthesis. Liquid sodium is colorless or yellow viscous, it is corrosive and flammable. Solid sodium methoxide is a colorless and amorphous powder, which can be decomposed into methanol and sodium hydroxide when water is encountered.
Alkaline method sodium methoxide is composed of solid sodium hydroxide and sodium methanol according to certain proportion, stir to dissolve obtained after precipitate removal of solid impurities, clear liquid pump in treating dehydration reaction, pure methanol steam continuous dehydration reaction, from the bottom to join in tower from the bottom of products. The methanol steam containing water comes out from the top of the tower and enters the distillation system´╝îmethoxide with no water return to use.
Sodium method sodium methoxide is made up of metallic sodium and methanol as raw materials, the use of industrial methanol pump to methanol metering tank, 120 kg of sodium metal into the reaction kettle, into the nitrogen to the reaction kettle, add water and methanol to react. Reaction 2~3h to no bubble generation, can be made by adding the mixed storage tank.
Sodium methanol is more than alkali and is more stable, which can improve product quality and utilization.If you have the demand for this product, please contact us – Xiangbang Sodium Methoxide Co.Ltd

The Application of Sodium Borohydride

As we all known, Sodium Borohydride is used as water soluble reductant. It is reductant of carbonyl compound (aldehyde, ketone, acid, acid amide, acid anhydride, acid halogen, ester,enol ester, imide , lactone), carbonitriding chemicals (azide, diazo salts, hydrazone, imine, nitrile, oxime, nitro compound), peroxide and hydroperoxide.
Sodium Borohydride also can be used to remove color, smell of organic chemicals, used to control pollution and recycle noble metals, the production of drug and fine chemicals, or used in the production and recovery of catalyst.
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.
