Product Description

N,N-Dimethylformamide with CAS 68-12-2
DMF is a transparent liquid that can dissolve with water and most organic solvents. It is a common solvent for chemical reactions. Pure dimethylformamide has a special odor, while industrial or spoiled dimethylformamide has a fishy smell because it contains impurities of dimethylamine. The name comes from the fact that it is a dimethyl substitute for formamide (formic acid's amide), and both methyl groups are on N (nitrogen) atoms. Dimethylformamide is a polar (hydrophilic) non-proton solvent with high boiling point, which can promote the mechanism of SN2 reaction. Dimethylformamide is made from methyl formate and dimethylamine. Dimethylformamide is unstable (especially at high temperature) in the presence of strong bases such as sodium hydroxide or strong acids such as hydrochloric acid or sulfuric acid and is hydrolyzed to formic acid and dimethylamine. HCON + H2O (CH3) 2 - (CH3) 2 nh + HCOOH.

[purpose 1] as analytical reagent and solvent for ethylene resin and acetylene [2].
[purpose 2] it is an excellent organic solvent, used as a solvent for polyurethane, polyacrylonitrile and polyvinyl chloride, and as a raw material for extraction agent, medicine and pesticide chloramidine.
[purpose 3] dimethylformamide is not only a kind of chemical material with wide application, but also a kind of good solvent with wide application. It can be used for the synthesis of wet spinning and polyurethane of polyacrylonitrile fiber and other synthetic fibers. Used in plastic film making; It can also be used as paint remover. It also dissolves certain pigments with low solubility, making them characteristic of dyes. Dimethylformamide can be used for aromatics extraction and for the separation and recovery of butadiene from carbon quarts and isoprene from carbon pentads. It can also be used as an effective reagent for the separation of non-hydrocarbon components from paraffin wax. It has good selectivity to the solubility of m-benzoic acid and p-terephthalic acid: m-benzoic acid has a higher solubility in dimethylformamide than p-terephthalic acid, and can be separated by solvent extraction or partial crystallization in dimethylformamide. In the petrochemical industry, dimethylformamide is used as a gas absorber to separate and refine gases. In organic reaction, dimethylformamide is not only widely used as the solvent of reaction, but also an important intermediate of organic synthesis. Chloramidine can be produced in the pesticide industry.  Dimethylformamide catalyzes the hydrogenation, dehydrogenation, dehydrogenation and dehalogenation of hydrogen.

[use] nonaqueous solution titration reagent, vinyl resin and acetylene solvent, organic synthesis, photometry, gas chromatographic stationary liquid (highest use temperature 50 ℃, the solvent of methanol), C2 and C5 hydrocarbon separation analysis, and can and isobutylene - [1] is suitable butene and anti - [2]. Analysis of pesticide residues. Organic synthesis. Peptide synthesis. For the photographic industry.
