Ibirango by'ibicuruzwa

Ikoreshwa:Dimethylamide (DMF) ni igikoresho cy'ingenzi cya shimi kandi gifite ubushobozi bwo gusukura, gikoreshwa cyane cyane mu nganda nka polyurethane, acrylic, imiti, imiti yica udukoko, amarangi, ibikoresho by'ikoranabuhanga, nibindi. Nk'umuti woza no gukaraba mu nganda za polyurethane, ikoreshwa cyane cyane mu gukora uruhu rw'ubukonje; Nk'umuti ukoreshwa mu nganda zikora imiti, ikoreshwa cyane mu gukora imiti ya doxycycline, cortisone, na sulfonamide; Nk'umuti ukoreshwa mu nganda zikora fibre za acrylic, ikoreshwa cyane cyane mu gukora imigozi ya acrylic yumye; Ikoreshwa mu nganda zikora imiti yica udukoko mu gukora imiti yica udukoko ikora neza kandi ifite uburozi buke; Ikoreshwa nk'umuti ukoreshwa mu nganda zikora amarangi; Kuzimya ibice by'amabati no gusukura ibyuma bikoreshwa mu nganda zikora ibikoresho by'ikoranabuhanga; Izindi nganda zirimo gutwara imyuka ihumanya, imiti ikoreshwa mu gukaraba imiti, kole, nibindi.

Izina ry'imiti: N, N-dimethylacetamide

Dimethylacetamide ni solvent ikomeye ya polar non protonated ishobora gushonga ibintu bitandukanye kandi ikavangwa burundu n'amazi, ether, ketones, esters, nibindi. Ifite ubushobozi bwo gushyuha cyane, irwanya hydrolysis nkeya, irangirika nkeya, kandi ifite uburozi bukeya. Ifite ubushobozi bwo gushonga neza kuri resin zitandukanye, cyane cyane polyurethane resin na polyimide resin, kandi ishobora gukoreshwa nk'umusemburo ku migozi ya sintetike idashyuha, filime za pulasitiki, irangi, imiti, na acrylonitrile spinning. Dimethylacetamide, nk'umusemburo muto, umusemburo mwinshi, hamwe n'umusemburo mwinshi wa polarity non proton solvent na chemical intermediate, ikoreshwa cyane mu bintu nk'ibikoresho bya sintetike, imiti, imiti yica udukoko, imigozi ya shimi, gutunganya peteroli, n'ibimera by'umwimerere.

Ni iyihe mikoreshereze y'ingenzi ya dimethyl formamide?

01ikoreshwa nk'ikintu gisesengura kandi kigatuma habaho umuti wa ethylene resin na acetylene

02ni umuti mwiza cyane ukoreshwa mu gushonga polyurethane, polyacrylonitrile, na polyvinyl chloride, ndetse no mu bikoresho fatizo bikoreshwa mu gusohora imiti, imiti n'imiti yica udukoko nka imidacloprid.

03Dimethylformamide si ibikoresho fatizo bikoreshwa cyane gusa, ahubwo ni solvent nziza ifite akamaro kanini. Dimethylformamide ni solvent nziza ku ma polymer menshi nka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, nibindi. Ishobora gukoreshwa mu kuzunguruka imigozi ya sintetike nka polyacrylonitrile no gukora polyurethane; Ikoreshwa mu gukora filime ya pulasitiki; Ishobora kandi gukoreshwa nk'umuti ukuraho irangi mu gukuraho irangi; Ishobora kandi gushonga amarangi amwe na amwe adashonga neza, ikayaha imiterere y'irangi. Dimethylformamide ikoreshwa mu gukuramo hydrocarbon ihumura neza, ndetse no gutandukanya no kugarura butadiene mu gice cya C4 na isoprene mu gice cya C5. Ishobora kandi gukoreshwa nk'umuti mwiza mu gutandukanya ibice bitari hydrocarbon na parafini. Ifite ubushobozi bwiza bwo guhitamo aside isophthalic na aside terephthalic: gushonga kwa aside isophthalic muri dimethylformamide ni byinshi kuruta uko biri muri aside terephthalic. Gukuramo ibintu bishongesha cyangwa gushushanya igice cyabyo muri dimethylformamide bishobora gutandukanya byombi. Mu nganda zikora peteroli, dimethyl formamide ishobora gukoreshwa nk'ikintu gikurura umwuka mu gutandukanya no gutunganya imyuka. Mu nganda zikora ibikomoka ku bimera, dimethylformamide ntikoreshwa cyane nk'ikintu gishongesha umwuka gusa, ahubwo ikoreshwa kandi nk'ikintu cy'ingenzi mu gukora organic synthesis. Ishobora gukoreshwa mu gukora chlorpyrifos mu nganda zirwanya udukoko; Mu nganda zikora imiti, ishobora gukoreshwa mu gukora pyrimidine iyode, doxycycline, cortisone, vitamine B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, aside antineoplastic, methoxyaromaine, bianzapine, cyclohexanone nitrourea, furfouracil, aside hemostatic, Fenfenmethasone, medroxyprogesterone, biliveratrol, chlorpheniramine, n'ibindi. Dimethylformamide igira uruhare mu gukurura umwuka mu kongera umwuka, gukuraho umwuka mu mubiri, kubura umwuka mu mubiri, no gukuraho umwuka mu mubiri, ikagabanya ubushyuhe bw'ibintu bishongesha umwuka no kunoza ubuziranenge bw'ibicuruzwa.

04Ikoreshwa mu gupima amazi ritari amazi, ikoreshwa mu gupima ethylene resin na acetylene, ikoreshwa mu gupima organic synthesis, fotometri, gaz chromatography stationary phase (ubushyuhe ntarengwa bwo gukora 50 ℃, solvent methanol), gutandukanya no gusesengura hydrocarboni C2-C5, hamwe n'ubushobozi bwo gutandukanya normal, isobutene, cis, na trans butene. Isesengura ry'ibisigazwa by'imiti yica udukoko. Ikoreshwa mu gupima organic. Ikoreshwa mu gufotora.
