Inganda Igiciro cyiza n, N-Dimethylformamide (DMF) kas 68-12-2
ibisobanuro
Izina riva ko ari ugusimbuza Dimethyl ya Dimethyl (ufite acide ya formatike), kandi amatsinda yombi ya Metyyl aherereye kuri n (atomeran) atom. N, N-DimeetHiDiD ni polar yo hejuru (hydrophilic) umudengeri, kandi imiti irashobora guteza imbere uburyo bwo gukora SN2. N, N-Dimeetlformamid Yakozwe ukoresheje aside ya pictic na dimethyhemine. N, N-DimeetHimImid idahindagurika (cyane cyane ku bushyuhe bwinshi) imbere yibanze nka sodium hydroxide cyangwa aside ikomeye kuri aside ya hydrochloric cyangwa aside ya hydrochloric cyangwa aside ya hydrochloric cyangwa aside sulfuric kuri acide na dimethylamine. Birahamye cyane mu kirere kandi iyo ashyushye guteka. Iyo ubushyuhe burenze 350 ℃, izatakaza amazi kandi ikabyara monoxide monoxide na dimethylamine. N, N-DimeetHiDimid ni porolar nziza ya aprotique, ishobora gusesa ibintu byinshi kandi bidashoboka, kandi bidashoboka, esters, hydrocarbone na hydrocarbone na hydrocarbone, nibindi. Iherezo rya N, N-DimeetLformid Molekid akikijwe nitsinda rya methyl, rikora imbogamizi ya methic, kugirango ion mbi idashobora kwegera, ariko ion nziza gusa ifitanye isano. Anion yambaye ubusa irakora cyane kuruta anion ikennye. Ibisubizo byinshi bya Ionic bikorwa byoroshye muri n, N-Dimethylformamid Kurenzabiga, urugero, reaction ya Cardonamiste ifite Hydrocarbone muri N, N-DimecarLamid ya Hydrocarbone muri N, N-Dimerifformamid ya Hydrocarbone muri N, N-DimecarLamid ya Hydrocarbone muri N, N-Dimerifmu. synthesis yo kubuzwa gukabije.

Gusaba DMF
DMF ni ikintu cyiza cyane kuri polymers zitandukanye nka polyide, polyintle, polyacrylonike, nibindi. Ikoreshwa mu gukora firime ya plastike; Irashobora kandi gukoreshwa nkumurongo urangi kugirango ukureho irangi; Irashobora kandi gushonga pigment yoroheje, kuburyo pigment ifite ibiranga kuri dyes. DMF ikoreshwa mugukuramo impumuro no gutandukana no kugarura Butadiene kuva C4 Ibice bya C5 na ISoprene muri C5 Ibice bya C5, kandi birashobora kandi gukoreshwa nkuburyo bwiza bwo gutandukanya ibice bitari Hydrocarbon kuva kuri Parafrocan. Ifite uburyo bwiza bwo kukecururizwa na aside ya isophthalic hamwe na acide terephthalic: aside ya isophtha. Mu nganda za Petrochemil, DMF irashobora gukoreshwa nka gaze ikurura kandi igatunganya imyuka. Nkumukozi wo gukinisha gukaraba igitabo munganda cya Polinethane, gikoreshwa cyane cyane mu musaruro wuruhu rwa synthetic; Nkumuco mu nganda za fibre ya acrylic, zikoreshwa cyane mu musaruro wumye wa fibre ya acrylict; Mu nganda za elegitoroniki nko kwizihiza ibice hamwe no ku mbuga z'umuriro izindi nganda zirimo abatwara imiti iteye ubwoba, ibiti byo guhagarika ibiyobyabwenge, ibiyobyabwenge, ibi n'ibindi ntabwo bikoreshwa cyane, ariko Kandi kandi byingenzi muri synthesis kama. Mu nganda zica udukoko, irashobora gukoreshwa mu gukora ciprofloxacin; Mu nganda za farumasi, irashobora gukoreshwa muguhindura iyode, doxycycline, cortisone, vidamine, Bilevita, Chlorlophendemine, umusaruro wa Sulfonamide. DMF ifite ingaruka za kataletitique mubisubizo bya hydrognation, umwuma uvanaho, umwuma no kurwara amazi, kugirango ubushyuhe bugabanurwe, kugirango ubushyuhe bugabanuke kandi ibicuruzwa bitunganijwe bitera imbere.
1.
2. Ikoreshwa nk'isesengura rya reagent kandi ukemuke kuri vinyl resin na acetylene
3. Ntabwo ari ibikoresho fatizo gusa bifite uburyo bunini bwo gukoresha, ariko nanone udukoko ryiza hamwe nuburyo bunini. DMF ni ikintu cyiza cyane kuri polymers zitandukanye nka polyide, polyintle, polyacrylonike, nibindi. Ikoreshwa mu gukora firime ya plastike; Irashobora kandi gukoreshwa nkumurongo urangi kugirango ukureho irangi; Irashobora kandi gushonga pigment yoroheje, kuburyo pigment ifite ibiranga kuri dyes. DMF ikoreshwa mugukuramo impumuro no gutandukana no kugarura Butadiene kuva C4 Ibice bya C5 na ISoprene muri C5 Ibice bya C5, kandi birashobora kandi gukoreshwa nkuburyo bwiza bwo gutandukanya ibice bitari Hydrocarbon kuva kuri Parafrocan.

Mu nganda za Petrochemil, DMF irashobora gukoreshwa nka gaze ikurura kandi igatunganya imyuka. Mubyitwaramo kama, DMF ntabwo ikoreshwa cyane nkigisubizo cyo kubyakira, ariko nanone hagati muri synthesis kama. Mu nganda zica udukoko, irashobora gukoreshwa mu gukora ciprofloxacin; Mu nganda za farumasi, irashobora gukoreshwa muguhindura iyode, doxycycline, cortisone, kaclothesin, umubyimba, froranlsearcominami, qurransfate ya sinapi, furoflsiroar, acide, acide, Mestrol, BilevItamin, Chlorlophendemine, nibindi DMF ifite ingaruka za kataletike mubisubizo bya hydrogenation, umwuma uvanaho, kuburyo ubushyuhe bugabanuka, kugirango ubushyuhe bugabanuke, kubwubushyuhe butera imbere.
4. Gukemura vinyl na acetylene. Kwiyemeza. Gazi ya chromatografiya (ubushyuhe ntarengwa bwa 50 ℃, Solven ni Methanol), kandi irashobora gutandukanya ibisanzwe c2 ~ c5 hydrocarbone, kandi irashobora gutandukanya ibisanzwe, isobutene na ci-butune.
