Consuetudinem:Dimethylamide (DMF) magna est materia chemica rudis et summus effectus solvens, maxime adhibitus in industriis ut polyurethanis, acrylicis, pharmaceuticis, pesticidis, fucis, electronicis, etc. Sicut lavatio et curatio agentis in industria polyurethane, maxime est. usus est in productione synthetica corio humido;Sicut syntheticum pharmacum medium in industria pharmaceutica, late adhibetur in productione doxycyclina, cortisone et sulfonamide medicamenta;Cum solvendo in acrylico fibrarum industria, maxime adhibita est ad productionem fibrarum acrylicarum aridorum lanarum;In pesticide industria usus est ad synthesisandam noxiam efficientem et humilem toxicitatem pesticidarum;Tinctura idoneus in tinctura usus est industria;Restinguere tinctae partes et purgatio tabularum in ambitu electronicarum industriae;Aliae industries includunt vehicula ancipitia gasorum, menstrua medicamentorum crystallizationis, adhaesivarum, etc.

Nomen chemicum: N, N-dimethylacetamide

Dimethylacetamida est fortis polaris non protonata solvens quae varias compositiones dissolvere potest et cum aqua, aethere, ketonibus, estersis penitus miscibilia est, etc. Habet stabilitatem thermarum altam, resistentiam hydrolysis humilem, corrosionem humilem, et toxicitatem humilem.Solubilitatem bonam habet ad varias resinas, praesertim resinam polyurethanam et resinam polyimidem, ac uti potest solvendo pro fibris syntheticis caloris repugnantibus, membrana plastica, tunicas, pharmaceuticas et acrylonitriles lanas.Dimethylacetamide, ut humilis toxicitas, alta fervens, et alta verticitas protonia non solvens et chemica media, late in campis adhibetur ut materia synthetica, pharmaceutica, pesticides, fibrae chemicae, processus petrolei, et pigmenta organica.

Quae sunt usus principalis dimetriae formamide?

01usus est in analytica reagens et solvendo pro ethylene resina et acetylene

02optimum organicum solvens adhibitum ut solvens pro polyurethane, polyacrylonitrile et chloride polyvinyl, nec non materia rudis extractantibus, pharmaceuticis et pesticidis ut imidaclopridis.

03Dimethylformamide non solum late usus est materia chemica rudis, sed etiam optima solvens cum amplis usuum amplis.Dimethylformamideum est bonum solvendo variis polymerorum altis, ut polyethylene, chloridi polyvinyl, polyacrylonitrile, polyamide, etc. Adhiberi potest pro umida nere fibrarum syntheticorum ut polyacrylonitrilium fibrarum et synthesis polyurethani;Pelliculae faciendae ad usum plasticum;Potest etiam adhiberi ut remouens fucus ad pingendum tollendum;Potest etiam quaedam vilia pigmenta solubilitatem dissolvere, eis notas colorum dans.Dimethylformamide adhibetur pro hydrocarbon extractione aromatica, tum pro butadiene a fractione C4 et isoprene ab C5 fractione separando et recipiendo.Potest etiam adhiberi ut reagens efficax ad separandum componentes hydrocarbon a paraffin non.Solubilitatem acidi isophthalici et acidi terephthalici bonum habet selectivity: maior est solubilitas acidi isophthalici in dimethylformamide quam in acido terephthalico.Extractio solvenda vel crystallizationis partialis in dimethylformamide duas separare potest.In industria petrochemical, dimethyl formamide uti potest sicut gas absorbens ad gasorum separandos et expoliendos.In reactionibus organicis dimethylformamide non solum late ut solvendo adhibetur, sed etiam medium magni ponderis in synthesi organica.Adhiberi potest chlorpyrifos in pesticide industria;In pharmaceutica industria, ad synthesisandam pyrimidinem iodidam, doxycyclinam, cortisonem, vitaminum B6, iodoside, Qubijing, thiapyrimidinem, N-formyl sarcolysin, acidum antineoplasticum, methoxyaromaine, bianzapinum, cyclohexanonem nitrourea, hencos, acidium, medroxya- nmethastrem. biliveratrol, chlorpheniramine, et sic porro.Dimethylformamide munus catalyticum agit in hydrogenatione, dehydrogenatione, siccitatibus, et reactionibus dehalogenationis, reducendo reactionem temperatam et puritatem producti melioris.

04Non aquea solutio titrationi reagens, solvendo pro resina ethylene et acetylene, synthesi organica, photometria, gasi chromatographia stationaria (maxima temperatura 50 , methanolum solvendum), separationem et analysis hydrocarbonum C2-C5, et facultas dividendi normalem, isobutenam. , cis et trans butene .Residuum analyseos pesticide.Synthesis organica.Peptide synthesis.Usu in consequat parturient.
