Fabricante bonum Price N, N-Dimethylformamide (DMF) CAS 68-12-2
descriptio
Nomen est ex eo quod est in substitutione formamide (acidum formica) et methyl coetus sunt sita in N (NITROGENIUM) Atom. N, N-Dimethylformamid est summus ferventis Suspendisse (Hydrophilic) Aprotic solvendo et chemicalbook libri potest promovere SN2 reactionem mechanism. N, N-Dimethylormamid est produci per formic acidum et Dimethylamine. N, n-Dimethylformamid est inconstans (praesertim ad altum temperatus) in praesentia fortis bases ut sodium hydroxide vel fortis acidis ut hydrochloric acidum et sulphuric acida et hydrochloric acidum et Dimethylamine. Est stabilis in aere et cum calefacta ferveret. Cum temperatus est altior quam CCCL ℃, perdet aqua et generate carbon monoxide et Dimethylamine. N, N-Dimethylformamid est bonum subsidiosum solutam solvendo, quod potest dissolvere maxime organicum et inorganicis substantiis, et miscible cum aqua, alcohols, aldeheohols hydrocarbons, etc. Et positive praecepit finis N, n-Dimethylformamid moleculo circumdatur a methyl coetibus, formatam a steric impedimentum, ut negative ions non potest accedere, sed solum positivum ions non possunt, sed solum positivum ions sunt consociata. Nudus anio multo magis activae quam solvated anion. Many ionic reactions are more easily carried out in N,N-DIMETHYLFORMAMID than in general protic solvents, for example, the reaction of carboxylates with halogenated hydrocarbons in N,N-DIMETHYLFORMAMID at room temperature , can generate high-yield esters, especially suitable for et synthesis sterically impediebat esters.

Applications de DMF
DMF est bonum solvent pro varietate alta polymers ut polyethylene, polyvyl chloride, polyacrylonitrile, polyamide, etc., et potest adhiberi pro infectum spheadica fibris ut PolyacryLonitrile fibris et synthesim; Est usus ad plastic film faciens; Potest etiam esse sicut pingunt DENUDATOR ad removere pingere; Potest etiam solvere aliquid humilis-solubility pigmenta, ut pigmentis habere proprietates dyes. DMF adhibetur ad aromaticum extractionem et separationem et convaluisset de butadiene a C4 fractiones et Isoprene a C5 fractionum, et potest esse quod efficax accidit ad separationem non-hydrocarbon components ex paraffin. Hoc est bonum selectivity ad solubility isophthaic acid et Terephthaic acid: isophthaica acid est solutum in DMF quam Terephthaalzation acidum, solvendo extractionem vel partialis crystallization, duo separari potest. In petrochemical industria, dmf potest adhiberi ut a Gas absorbent ut separate et conflentur gasorum. Sicut curing agente ad baptismata chemicalbook in polyurethane industria, quod maxime usus est in productio infectum Saccharum zonam; Sicut solvendo in acrylic alimentorum fibra industria, id est maxime in aridam spheara productio of acrylic alimentorum fibra; In electronic industria ut a extinguatur de stagni-patella partes et circuitu tabulas alii industries includit carriers de periculo vapores, solvents pro medicamento crystallization, adhesives, non solum ut solvendo in reactionem, nisi Etiam an maximus medium in organicum synthesis. In pesticide industria, quod potest esse ad producendum Ciprofloxacin; in the pharmaceutical industry, it can be used to synthesize iodine, doxycycline, cortisone, vitamin B6, iodine, quercetin, pyrantel, N-formylsarcomin, Oncoline, methoxyfen, benzodiazepine, cyclohexyl nitrosourea, furoflurouracil, hemostatic acid, bepartame, MEGESTROL, BILEVITIS, Chlorpheniramine, Sulfonamides productio. DMF habet a catalytic effectus in reactiones hydrogenation, dehydrogenation, siccitatibus et dehydrohalogenation, ut reactionem temperatus est deposuit et uber puritas est melius.
I. Non est optimum organicum solvendo, usus est ut solvendo pro Polyurethane, PolyacryLonitrile et polyovinyl chloride, et quoque usus est in extractu, sicut rudis materia et medicamina et pesticides.
II. Usus est analyticae Reagent et solvendo pro Vinyl resinam et acetylene
III. Non solum a chemical rudis materia cum amplis usus, sed etiam optimum solvendo cum amplis usus. DMF est bonum solvent pro varietate alta polymers ut polyethylene, polyvyl chloride, polyacrylonitrile, polyamide, etc., et potest adhiberi pro infectum spheadica fibris ut PolyacryLonitrile fibris et synthesim; Est usus ad plastic film faciens; Potest etiam esse sicut pingunt DENUDATOR ad removere pingere; Potest etiam solvere aliquid humilis-solubility pigmenta, ut pigmentis habere proprietates dyes. DMF adhibetur ad aromaticum extractionem et separationem et convaluisset de butadiene a C4 fractiones et Isoprene a C5 fractionum, et potest esse quod efficax accidit ad separationem non-hydrocarbon components ex paraffin. Hoc est bonum selectivity ad solubility isophthaic acid et Terephthaic acid: Isophthaalum acidum est solutum in DMF quam TerePhthaal acid, solvendo extraction est in Dimethylized, duo possunt separari. In petrochemical industria, dmf potest adhiberi ut a Gas absorbent ut separate et conflentur gasorum. In organicum reactiones, DMF non solum late solebat sicut solvendo ad reactionem, sed etiam momenti intermedii in organicum synthesim. In pesticide industria, quod potest esse ad producendum Ciprofloxacin; In pharmaceutical industria, quod potest esse in synthesize Iodum, Doxycycline, cortisone, Vitaminum B6, iode, quercetin, pyrantel, n-formylsarcomin, tumorine, pyrantel, nitrosourea, tumorine, cyclohexyl, bian Nitrogen, Hemostatic acidum, bian Nitrogen, hemostatic acidum, bian Nitrogen, Hemostatic acidum, bian Nitrogen, Hemostatic acidum, bian Nitrogen, Hemostatic acidum, bian Nitrogen, hemostatic acidum, bian Nitrogen, hemostatic acidum, bian Nitrogen, hemostatic acidum, bian Nitrogen, Hemostatic acidum, bian Nitrogen, Hemostatic Acidum, Bepartam: MEGESTROL, Bilevitamin, chlorpheniramine, etc. DMF habet a catalytic effectus in reactiones Hydrogenation, Dehydrogenation, siccitatibus et dehydrohalogenation, ita quod motus temperatus est deposuit et uber castitatem est melius.
IV. Non aqueum titrationis solvente. Solvent enim Vinyl et acetylene. Photometric determinatio. Gas chromatographic stabilem solution (maximum operating temperatus L ℃, solvendo est methanolum), separationem chemicalbook Analysis C2 ~ C5 hydrocarbons, et potest separare normalis, isobutene et Cis, trans-II-butene. Pesticide residuum analysis. Organicum synthesis. Peptide synthesis. Ad photographic industria.
