Mugadziri Akanaka Mutengo N, N-DimethylfMide (DMF) CAT 68-12-2
Tsananguro
Iro zita rinobva pane chokwadi kuti ndiyo dimethyl kutsiva kweFortamide (endege of mafomu (uye maviri methyl mapoka ari paN (nitrogen) atomu. N-n-dimethylformid idhodhi yakakwira (hydrophilic) Aprotic Solvent, uye kemakemikari inogona kusimudzira iyo Sn2 Reaction Mechanism. N, n-dimethylformid inogadzirwa uchishandisa mafomu acid uye dimethylamine. N, n-dimethylformid haina kugadzikana (kunyanya pakupisa kwakanyanya) pamberi pezvikepe zvakashata senge hydrochloric acid, uye hydrolyzir acid uye dimethylamine. Iyo yakagadzikana kwazvo mumhepo uye kana ichipiswa kuti itadzike. Kana tembiricha yakakwira kupfuura 350 ℃, icharasikirwa nemvura uye inoburitsa kabhoni monoxide uye dimethylamine. N-n-dimethylformid yakanaka yekuparadza solvent, iyo isinganyanye nemvura, uye inokanganisa mvura, makona, esters hydrocarbons uye inonhuhwirira hydrocarbons, nezvimwe. Iyo yakanaka inopiwa mugumo weN, N-DIMETHELFORMID mapoka methyl Anonhuwa asina kusimira anonyanya kushanda kupfuura iyo yakagadziriswa nalvan. Zvakawanda IONIC iyo synthesis yekudzivisa kushamisika esters.

Zvikumbiro zveDMF
DMF ishoma solvent yemhando dzakasiyana-siyana dzePolythers dzakadai saPolyethyl chloride, polyvinyl chloride, polywireshlene Iyo inoshandiswa kune epurasitiki yemafirimu kugadzira; Inogona zvakare kushandiswa sependi stripper yekubvisa pendi; Izvo zvinogona zvakare kugumbura zvimwe-pigment-solubility pigmenti, zvekuti iyo pigment ine maitiro emakadhi. DMF inoshandiswa kurwiswa kweiyo inonhuhwirira uye kupatsanurwa uye kupora kweButtione kubva kuC4 Zvikamu zveC5 Iyo ine sarudzo yakanaka yeiyo solubility ye istophaal acid uye terephthaal acid: isophthalal acid pane terephthalic. Muindasitiri wepeturu, DMF inogona kushandiswa segasi inobata kupatsanura uye kunatsiridza magasi. Semumiriri kurapa kwekushambidza kemichbook muPolyurethane indasitiri, inonyanya kushandiswa mukugadzirwa kweiyo yakanyorova yeganda; Semunhu solvent muAcrylic fier indasitiri, inonyanya kushandiswa mune yakaoma spinning kugadzirwa kweAcrylic fiber; Mune indasitiri yemagetsi sekutsvuka kwetini-yakarongedzwa mabhodhi mamwe maindasitiri anosanganisira maindasitiri emagasi ane njodzi, etc. Mugadziri esimba chete, asi Zvakare zvakakosha pakati mu organic synthesis. Muindasitiri ye pesticide, inogona kushandiswa kuburitsa ciprofloxacin; muindasitiri yechechi, inogona kushandiswa kuSynthescline, Doxycycline, Cortamin, vitindia, Nzira yeNyika, Highaticaracil, Hepofic Bilevita, Clevheriramine, kugadzirwa kweSarufoniides. DMF ane chekuita nehurongwa hwekuita hydrogenation, kushomeka, kushomeka uye dehydroharogenational
1. Iyo inzvimbo yakanaka kwazvo, inoshandiswa solvent ye polyurethane, polyacrylonitrile, uye yakashandiswawo seyeti, sechinhu chakabikwa chemishonga nemishonga yekuuraya zvipuka.
2. Inoshandiswa sekuongorora auyemast uye solvent ye vinyl resin uye acetylene
3. Haisi chete Chemical SRAW zvinyorwa zvine huwandu hwakawanda hwekushandisa, asi zvakare solvent yakanakisa neyakawandisa yekushandisa. DMF ishoma solvent yemhando dzakasiyana-siyana dzePolythers dzakadai saPolyethyl chloride, polyvinyl chloride, polywireshlene Iyo inoshandiswa kune epurasitiki yemafirimu kugadzira; Inogona zvakare kushandiswa sependi stripper yekubvisa pendi; Izvo zvinogona zvakare kugumbura zvimwe-pigment-solubility pigmenti, zvekuti iyo pigment ine maitiro emakadhi. DMF inoshandiswa kurwiswa kweiyo inonhuhwirira uye kupatsanurwa uye kupora kweButtione kubva kuC4 Zvikamu zveC5 Iyo ine sarudzo yakanaka yeiyo solubility yeisiophthalal acid uye terephthaal acid: isophthalic acid yemaptiki, solvething Muindasitiri wepeturu, DMF inogona kushandiswa segasi inobata kupatsanura uye kunatsiridza magasi. Muchiitiko chesangano, DMF haina kungo shandiswa zvakanyanya sechigadzika chekuita, asi zvakare chakakosha pakati mu orghic synthesis. Muindasitiri ye pesticide, inogona kushandiswa kuburitsa ciprofloxacin; muindasitiri yemisheni, inogona kushandiswa kuSynthescline, Doxycycline, Cortamin, Vitinini, Nitroxyl Meletrol, Bilevithamini, Clorpheriramine, etc. DMF ine maitiro ehuswa mune hydrogenation, kushomeka uye kushomeka kwekutsiva kwakaderedzwa uye kuchena kwechigadzirwa kunovandudzwa.
4. Kwete-kuseri kwegumi solvent. Solvent ye vinyl uye acetylene. Zveshuwa. Gasi Chromatographic Somiganhu Solitional Soliturity (Maximum Inoshanda tembiricha 50 ℃, Solvent Chemicalbook Ongorora C2 ~ C5 Hydrocarbons, uye isobutencarbons, uye isobutene uye isobutene uye Cis, trans-2-butene.
