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 ni polarike itetse cyane (hydrophilique) aprotic solvent, kandi Igitabo cya Chemical gishobora guteza imbere uburyo bwa SN2. 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 molekile ya N, N-DIMETHYLFORMAMID ikikijwe nitsinda rya methyl, ikora inzitizi ikomeye, kuburyo ion mbi idashobora kwegera, ariko ion nziza gusa zirahuzwa. Anion yambaye ubusa irakora cyane kuruta anion ikemuwe. Imyiyerekano myinshi ya ionic ikorwa muburyo bworoshye muri N, N-DIMETHYLFORMAMID kuruta mumashanyarazi rusange ya protic, kurugero, reaction ya carboxylates hamwe na hydrocarbone ya halogene muri N, N-DIMETHYLFORMAMID mubushyuhe bwicyumba, irashobora kubyara ester zitanga umusaruro mwinshi, cyane cyane zikwiranye na synthesis ya ester ikumirwa cyane.

Porogaramu ya DMF
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: 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 Shimi mu nganda 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 hamwe n’imbaho z’umuzunguruko Izindi nganda zirimo abatwara imyuka iteje akaga, umusemburo wo korohereza ibiyobyabwenge, imiti, n'ibindi. Mu nganda zica udukoko, irashobora gukoreshwa mu gukora ciprofloxacin; mu nganda zimiti, irashobora gukoreshwa muguhuza iyode, doxycycline, cortisone, vitamine B6, iyode, quercetin, pyrantel, N-formylsarcomin, Oncoline, vitokxyfen, benzodiazepine, cyclohexyl nitrosourea, furoflurouracil, hemostatic me, acide hemostatike, Umusaruro wa sulfonamide. DMF igira ingaruka za catalitiki mubitekerezo bya hydrogenation, dehydrogenation, dehydrasi na dehydrohalogenation, kuburyo ubushyuhe bwibisubizo bugabanuka kandi ubuziranenge bwibicuruzwa bugahinduka.

2. Ikoreshwa nka analytique reagent na solvent kuri vinyl resin na acetylene
3. Ntabwo aribikoresho bya chimique gusa bifite imiti myinshi ikoreshwa, ahubwo ni umusemburo mwiza cyane hamwe nuburyo 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 muguhuza iyode, doxycycline, cortisone, vitamine B6, iyode, quercetin, pyrantel, N-formylsarcomin, Tumorine, sinapi Methoxyfen, sinapi ya Bian azote, cyclohexyl nitrosourea, furoflurouracil, hemostatic aside n'ibindi.
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.
