Magaca kiimikada: N, N-dimethylacetamide
Dimethylacetamide waa dareere xooggan oo aan lahayn protonated polar ah kaas oo milmi kara iskudhisyo kala duwan isla markaana si buuxda ula milmi kara biyaha, ethers, ketones, esters, iwm. Waxay leedahay xasillooni kuleyl oo sareysa, iska caabin hydrolysis oo hooseeya, daxal hoose, iyo sunta yar. Waxay leedahay milmi wanaagsan oo loogu talagalay resins kala duwan, gaar ahaan resin polyurethane iyo resin polyimide, waxaana loo isticmaali karaa dareere ahaan fiilooyinka synthetic-ga ee u adkaysta kulaylka, filimada balaastikada ah, dahaarka, daawooyinka, iyo wareegga acrylonitrile. Dimethylacetamide, oo ah sunta yar, dhibic karkaraya oo sareysa, iyo dareere aan proton ahayn oo sareeya iyo dhexdhexaad kiimiko ah, ayaa si weyn loogu isticmaalaa beeraha sida walxaha synthetic-ga, daawooyinka, sunta cayayaanka, fiilooyinka kiimikada, farsamaynta batroolka, iyo midabada dabiiciga ah.
Waa maxay isticmaalka ugu muhiimsan ee dimethyl formamide?
01loo isticmaalo sidii falanqayn falanqayn iyo dareere loogu talagalay ethylene resin iyo acetylene
02waa dareere dabiici ah oo aad u fiican oo loo isticmaalo dareeraha polyurethane, polyacrylonitrile, iyo polyvinyl chloride, iyo sidoo kale walxo cayriin ah oo loogu talagalay soosaarayaasha, daawooyinka, iyo sunta cayayaanka sida imidacloprid
03Dimethylformamide ma aha oo kaliya walxo kiimiko ceeriin ah oo si weyn loo isticmaalo, laakiin sidoo kale waa dareere aad u fiican oo leh isticmaallo badan. Dimethylformamide waa dareere wanaagsan oo loogu talagalay polymers-ka kala duwan ee sare sida polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, iwm. Waxaa loo isticmaali karaa wareejinta qoyan ee fiilooyinka synthetic-ga sida fiilooyinka polyacrylonitrile iyo isku-darka polyurethane; Waxaa loo isticmaalaa sameynta filimada balaastikada ah; Waxaa sidoo kale loo isticmaali karaa sidii ka-saarista rinjiga si looga saaro rinjiga; Waxay sidoo kale milmi kartaa midabyo gaar ah oo milmi kara oo hooseeya, taasoo siinaysa astaamaha midabaynta. Dimethylformamide waxaa loo isticmaalaa soo saarista hydrocarbon-ka udgoonka leh, iyo sidoo kale kala soocida iyo soo celinta butadiene ee jajabka C4 iyo isoprene ee jajabka C5. Waxa kale oo loo isticmaali karaa sidii reagent wax ku ool ah si loo kala saaro qaybaha aan hydrocarbon ahayn iyo paraffin. Waxay leedahay xulasho wanaagsan oo loogu talagalay milmida isophthalic acid iyo terephthalic acid: milmida isophthalic acid ee dimethylformamide way ka weyn tahay tan terephthalic acid. Soo saarista dareeraha ama qayb ka mid ah kristantalka dimethylformamide ayaa kala saari kara labada. Warshadaha batroolka kiimikada, dimethyl formamide waxaa loo isticmaali karaa sidii dareere gaas ah oo loogu talagalay kala soocidda iyo sifaynta gaasaska. Falcelinta dabiiciga ah, dimethylformamide si weyn looguma isticmaalo oo keliya dareere ahaan, laakiin sidoo kale waa dhexdhexaad muhiim ah oo ku jira isku-darka dabiiciga ah. Waxaa loo isticmaali karaa in lagu soo saaro chlorpyrifos warshadaha cayayaanka dila; Warshadaha dawooyinka, waxaa loo isticmaali karaa in lagu sameeyo pyrimidine iodide, doxycycline, cortisone, fitamiin B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, antineoplastic acid, methoxyaromaine, bianzapine, cyclohexanone nitrourea, furfurouracil, hemostatic acid, Fenfenmethasone, medroxyprogesterone, biliveratrol, chlorpheniramine, iwm. Dimethylformamide wuxuu door ka ciyaaraa falgalka hydrogenation, dehydrogenation, fuuq-baxa, iyo falgalka dehalogenation, isagoo yareynaya heerkulka falcelinta iyo hagaajinta daahirnimada badeecada.
04Reagent-ka xalka aan biyaha lahayn ee titration, dareeraha resin ethylene iyo acetylene, synthesis organic, photometry, gaaska chromatography marxaladda taagan (heerkulka ugu badan ee hawlgalka 50 ℃, methanol dareeraha), kala soocida iyo falanqaynta hydrocarbons-ka C2-C5, iyo awoodda lagu kala saaro caadiga ah, isobutene, cis, iyo trans butene. Falanqaynta haraaga sunta cayayaanka. Isku-darka dabiiciga ah. Isku-darka Peptide. Waxaa loo isticmaalaa warshadaha sawir-qaadista.
