Uruganda Igiciro Cyiza N, N-DIMETHYLFORMAMIDE (DMF) CAS 68-12-2
ibisobanuro
Izina rituruka ku kuba ari dimethyl isimbuza formamide (amide ya acide formique), kandi amatsinda yombi methyl aba kuri atome ya N (azote).,N, N-DIMETHYLFORMAMID ikorwa hifashishijwe aside ya formic na dimethylamine.N.Irahagaze neza mumuyaga kandi iyo ishyushye kubira.Iyo ubushyuhe burenze 350 ℃, buzabura amazi kandi butange karubone monoxide na dimethylamine.N.Impera yuzuye neza ya N, N-DIMETHYLFORMAMID molekile ikikijwe nitsinda rya methyl, ikora inzitizi ikomeye, kuburyo ion mbi idashobora kwegera, ariko ion nziza gusa zirahuzwa.Anion yambaye ubusa irakora cyane kuruta anion ikemutse.Imyitwarire myinshi ya ionic ikorwa muburyo bworoshye muri N, N-DIMETHYLFORMAMID kuruta mubisanzwe muri protic solique, urugero, reaction ya carboxylates hamwe na hydrocarbone ya halogene muri N, N-DIMETHYLFORMAMID mubushyuhe bwicyumba, irashobora kubyara ester zitanga umusaruro mwinshi, cyane cyane zibereye synthesis ya esters ikumirwa.

Porogaramu ya DMF
DMF ni umusemburo mwiza kuri polymers zitandukanye nka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, nibindi, kandi irashobora gukoreshwa mukuzunguruka kwizunguruka ya fibre synthique nka fibre polyacrylonitrile, hamwe na synthesis ya polyurethane;Ikoreshwa mugukora firime ya plastike;irashobora kandi gukoreshwa nkumurangi wo gusiga irangi;irashobora kandi gushonga pigment zimwe na zimwe zidafite imbaraga, kugirango pigment igire ibiranga amarangi.DMF ikoreshwa mugukuramo aromatiya no gutandukana no kugarura butadiene ivuye mu bice bya C4 na isoprene ivuye mu bice bya C5, kandi irashobora no gukoreshwa nka reagent nziza yo gutandukanya ibice bitari hydrocarubone na paraffine.Ifite uburyo bwiza bwo guhitamo acide isophthalic na acide terephthalic: aside isophthalic irashobora gushonga cyane muri DMF kuruta aside terephthalic, gukuramo ibishishwa cyangwa igice cya Crystallisation, byombi birashobora gutandukana.Mu nganda zikomoka kuri peteroli, DMF irashobora gukoreshwa nkimashini ya gaze kugirango itandukane kandi inoze imyuka.Nkumuti ukiza wo koza igitabo cya chimique munganda za polyurethane, gikoreshwa cyane cyane mugukora uruhu rutose;nk'umusemburo mu nganda za fibre acrylic, ukoreshwa cyane cyane mukuzunguruka kwumye kwa fibre acrylic;mu nganda za elegitoronike nko kuzimya ibice bikozwe mu mabati no ku mbaho z’umuzunguruko Izindi nganda zirimo abatwara imyuka iteje akaga, umusemburo wo korohereza ibiyobyabwenge, imiti, n'ibindi. nanone intera ikomeye hagati muri synthesis.Mu nganda zica udukoko, irashobora gukoreshwa mu gutanga ciprofloxacin;mu nganda zimiti, irashobora gukoreshwa muguhuza iyode, doxycycline, cortisone, vitamine B6, iyode, quercetin, pyrantel, N-formylsarcomin, Oncoline, mikorerexyfen, benzodiazepine, cyclohexyl nitrosourea, furoflurouracil, hemostatic meide, aside chlorpheniramine, sulfonamide Umusaruro.DMF igira ingaruka za catalitiki mu myitwarire ya hydrogenation, dehydrogenation, dehydrasi na dehydrohalogenation, ku buryo ubushyuhe bwa reaction bugabanuka kandi ubuziranenge bwibicuruzwa bugahinduka.
1. Numuti mwiza cyane wumuti, ukoreshwa nkumuti wa polyurethane, polyacrylonitrile, na chloride polyvinyl, kandi ukanakoreshwa nkibikuramo, nkibikoresho fatizo byimiti yica udukoko.
2. Ikoreshwa nka analytique reagent na solvent kuri vinyl resin na acetylene
3. Ntabwo ari ibikoresho fatizo byimiti gusa hamwe nuburyo butandukanye bwo gukoresha, ahubwo ni umusemburo mwiza ufite uburyo bwinshi bwo gukoresha.DMF ni umusemburo mwiza wa polymers zitandukanye nka polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, nibindi, kandi irashobora gukoreshwa mukuzunguruka neza kwa fibre synthique nka fibre polyacrylonitrile, hamwe na synthesis ya polyurethane;Ikoreshwa mugukora firime ya plastike;irashobora kandi gukoreshwa nkumurangi wo gusiga irangi;irashobora kandi gushonga pigment nkeya-solubile pigment, kugirango pigment igire ibiranga amarangi.DMF ikoreshwa mugukuramo aromatic no gutandukana no kugarura butadiene ivuye mubice C4 na isoprene ivuye mubice C5, kandi irashobora no gukoreshwa nka reagent nziza yo gutandukanya ibice bitari hydrocarubone na paraffine.Ifite uburyo bwiza bwo guhitamo acide isophthalic na acide terephthalic: acide isophthalic irashobora gushonga cyane muri DMF kuruta aside terephthalic, gukuramo ibishishwa bikorwa muri acide ya dimethyl chimique acide formamide Cyangwa igice kimwe, byombi birashobora gutandukana.Mu nganda zikomoka kuri peteroli, DMF irashobora gukoreshwa nkimashini ya gaze kugirango itandukane kandi inoze imyuka.Mubisubizo kama, DMF ntabwo ikoreshwa cyane nkigisubizo cyibisubizo, ahubwo ni intera ikomeye muri synthesis.Mu nganda zica udukoko, irashobora gukoreshwa mu gukora ciprofloxacin;mu nganda zimiti, irashobora gukoreshwa mugushushanya iyode, doxycycline, cortisone, vitamine B6, iyode, quercetin, pyrantel, N-formylsarcomin, Tumorine, sinapi ya Methoxyfen, sinapi ya Bian azote, cyclohexyl nitrosourea, furoflurouracil, hemostatic acide , bilevitamine, chlorpheniramine, nibindi DMF igira ingaruka za catalitiki muguhindura hydrogenation, dehydrogenation, dehidrasi na dehydrohalogenation, kuburyo ubushyuhe bwibisubizo bugabanuka kandi ubuziranenge bwibicuruzwa bugahinduka.
4. Amashanyarazi adafite amazi.Umuti wa vinyl na acetylene.Kwiyemeza gufotora.Gazi ya chromatografi ihagaze neza (ubushyuhe ntarengwa bwo gukora 50 ℃, solvent ni methanol), gutandukanya Isesengura ryibitabo bya Chemical C2 ~ C5 hydrocarbone, kandi irashobora gutandukanya ibisanzwe, isobutene na cis, trans-2-butene.Isesengura ry'imiti yica udukoko.Synthesis.Peptide synthesis.Inganda zifotora.
