Product description
Dimethylformamide (DMF) is a colorless transparent liquid that can be miscible with water and most organic solvents. Pure dimethylformamide has a special odor, while industrial or deteriorated dimethylformamide has a fishy odor because it contains impurities of dimethylamine. The source of the name is because it is a dimethyl substitute of formamide (formamide), and both methyl groups are located on N (nitrogen) atom. It is a common solvent for chemical reactions.

Application
1. Used as an analytical reagent and solvent for ethylene resin and acetylene.
2. It is an excellent organic solvent used as a solvent for polyurethane, polyacrylonitrile, and polyvinyl chloride, as well as as as a raw material for extractant, medicine, and pesticide chlorpyrifos.
3. Dimethylformamide is not only a widely used chemical raw material, but also an excellent solvent with a wide range of uses. Can be used for wet spinning of synthetic fibers such as polyacrylonitrile fibers and the synthesis of polyurethane; Used for plastic film making; It can also be used as a paint remover for removing paint; It can also dissolve certain low solubility pigments, giving them the characteristics of dyes. Dimethylformamide can be used for aromatic hydrocarbon extraction, as well as for separating and recovering butadiene from C4 fraction and isoprene from C5 fraction. It can also be used as an effective reagent for separating non hydrocarbon components from paraffin. It has good selectivity for the solubility of isophthalic acid and terephthalic acid: the solubility of isophthalic acid in dimethylformamide is greater than that in terephthalic acid. Solvent extraction or partial crystallization in dimethylformamide can separate the two. In the petrochemical industry, dimethyl formamide can be used as a gas absorbent for separating and refining gases. In organic reaction, dimethylformamide is not only widely used as a solvent, but also an important intermediate in organic synthesis. It can be used to produce chlorpyrifos in the pesticide industry; In the pharmaceutical industry, it can be used to synthesize sulfadiazine, doxycycline, cortisone, vitamin B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, antineoplastic acid, methoxyaromaine, bianzapine, cyclohexylidene nitrourea, furfurouracil, hemostatic acid, Fenfenmethasone, medroxyprogesterone, biliveratrol, chlorpheniramine, and so on. Dimethylformamide plays a catalytic role in hydrogenation, dehydrogenation, dehydration, and dehalogenation reactions, reducing reaction temperature and improving product purity.
4. Reagents for non aqueous solution titration, solvents for ethylene resin and acetylene, organic synthesis, photometry, gas chromatography stationary phase (maximum operating temperature 50 ºC, solvent methanol), separation and analysis of C2-C5 hydrocarbons, and the ability to separate normal and isobutene - [1], cis and trans butene - [2]. Pesticide residue analysis. Organic synthesis. Peptide synthesis. Used in the photography industry.
