DMF(N,N-Dimethylformamide  CAS 68-12-2 ). A compound formed by substituting the hydroxyl group of formic acid with aN N Dimethylformamide for sale - Yuanfarchemicals dimethylamine group, HCON(CH3)2. It is a colorless and transparent liquid with high boiling point, which can cause combustion and explosion in case of open fire and high heat. It can react violently with concentrated sulfuric acid and fuming nitric acid and even explode. It is soluble with water and most organic solvents. It is a common solvent for chemical anti - Chemicalbook. Pure dimethylformamide is odorless, but industrial-grade or spoiled dimethylformamide has a fishy smell because it contains impurities of dimethylamine. DMF can be mixed arbitrarily with most organic solvents and water, and has good solubility in organic and inorganic compounds

Dimethylformamide is not only a chemical raw material with a wide range of uses, but also an excellent solvent with a wide range of uses. Dimethylformamide is a good soluble Chemicalbook agent for a variety of polymers such as polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide and so on. It can be used for wet spinning of synthetic fibers such as polyacrylonitrile fiber and the synthesis of polyurethane. Used for plastic film making; Can also be used as paint remover; It can also dissolve some low solubility pigments, pigments with dye characteristics.

Method Of Manufacturing DMF:

For the first time since 1899, with formic acid reaction with dimethylamine synthesis of dimethyl formamide, developed in different raw material for synthesis of dimethyl formamide process methods, such as dimethylamine carbon monoxide method, formamide dimethylamine, hydrogen cyanide acid - methanol, acetonitrile - methanol method, methyl formate - dimethylamine, chloral - dimethylamine and so on. However, dimethylamine - carbon monoxide is still the main method for industrial production abroad. 1. Methyl formate-dimethylamine method by formic acid and methanol esterification to generate methyl formate, and then with dimethylamine gas reaction to generate dimethylformamide, and then Chemicalbook by distillation to recover methanol and unreacted methyl formate after decompression distillation to get the finished product. Dimethylamine - carbon monoxide method by dimethylamine and carbon monoxide under the action of sodium methoxide, direct reaction. The reaction conditions were 1.5-2.5MPa and 110-150℃. The coarse product is rectified to produce the finished product. 3. Methyl formate is synthesized by carbonyl synthesis of carbon monoxide and methanol under high pressure and 80-100℃ temperature, and then reacts with dimethylformamide to generate dimethylformamide, and the finished product is obtained after rectification. 4 trichloroacetaldehyde method by trichloroacetaldehyde and dimethylamine reaction.China DMF - Yuanfarchemicals

Recently, the increase of DMF in The Chinese market is quite obvious, and the chart below is more clear,

The average price of DMF market rose this week compared with the week before the holiday. After the National Day, the supply of goods in the market was tight, and the main factory became

Hand in the price continues to rise, market businesses actively follow up. East China market for example, this week's average price of 15917 yuan/ton, sequential

Rose 8.77%. Market news before the National Day hualu Hengsheng a 100,000-ton production line temporarily stopped, Shaanxi Xinghua  HENan Jun chemical devices are not started, in addition, after the holiday related varieties of methylamine rise and profit are good, enterprises increase production intention

The corresponding OUTPUT of DMF decreases, resulting in tight supply of DMF. The downstream slurry is in demand forget, and the social inventory is low

After the emissary factory transaction prices continue to rise, businesses also actively follow up.
