Product Description

Product Description
Dimethylformamide (DMF) is a colorless, transparent liquid that is compatible with water and most organic solvents. Pure Dimethylformamide have a special odour, while industrial or spoiled Dimethylformamide have a fishy odor due to the presence of a dimet hylamine impurity. The name comes from the fact that it is a dimethyl substitute for formamide (the amide of for mic acid) , and both methyl groups are on the N (nitrogen) atom. It is a common solvent for chemical reactions. As a polar (hydrophilic) Protic solvent with high The boiling point, it facilitates The SN2 reaction mechanism. The Dimethylformamide is made from me thyl formate and dimeth ylamine. The Dimethylformamide is unstable in the presence of strong alkalis such as sodium  hydroxide or strong acids such as hydroch loric acid or sulfuric acid (especially at high temperatures) and hydrolyzes to for mic acid and dimeth ylamine,
APPLICATION
1,Used as analytical reagent and solvent of vinyl resin and acetylene.
2,It is an excellent organic solvent. It is used as a solvent for polyurethane, polyacrylonitrile and polyvinyl chloride, as well as As as an extractant, pharmaceutical and pesticide raw material for chlordi meform.
3,Dimethylformamide is not only an extremely versatile chemical raw material, but also an excellent solvent with a wide range of uses. It can be used for wet spinning of polyacrylonitrile fiber and other synthetic fibers, synthesis of polyurethane, plastic film, paint removal agent, and some pigments with low solubility, give the pigment the character of a dye. The Dimethylformamide can be used for aromatics extraction and for the recovery of Butadiene from C _ 4 and C _ 5 fractions, as well as for the recovery of isoprene 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 of terephthalic acid, solvent extraction in Dimethylformamide or partial crystallization, the two can be separated. In petrochemistry, Dimethylformamide is used as a gas absorbent to separate and refine gases. In organic reactions, Dimethylformamide are widely used not only as solvents but also as important intermediates in organic synthesis. The pesticide industry can be used to produce chlordim eform; In the pharmaceutical industry, it can be used to synthesize sulfadi azine, Doxyc ycline, cort isone, vitamin B6, iodic glycoside, vermicullin, thiopyrimidine, n-formylsarcomycin, antineoplastic acid, methoxyaromatic mustard, biannitrogen mustard, cyclohexanitrosourea, furosemide, tranexamic acid, pemetasone, medroxyprogesterone, Doxy cycline, chlorpheniramine, etc. . The Dimethylformamide is used as a catalyst in hydrogenation, dehydrogenation, dehydration and dehalogenation reactions, resulting in lower reaction temperature and higher purity of the product.
4,Reagent for non-aqueous solution titration, solvent of vinyl resin and acetylene, organic synthesis, photometric determination, gas chromatography stationary liquid (maximum temperature 50 ° C, solvent is me thanol) , separation and analysis of C2-C5 hydrocarbons, and can separate N-, isobutene-[1] and cis-, trans-butene-[2] . Analysis of pesticide residues. Organic synthesis. Synthesis of peptides. For the photographic industry.
