Igama leKhemikhali: N, N-dimethylacetamide
I-Dimethylacetamide yi-solvent eyomeleleyo ye-polar non protonated ekwazi ukunyibilika iikhompawundi ezahlukeneyo kwaye ixutywe ngokupheleleyo ngamanzi, ii-ethers, ii-ketones, i-esters, njl.Inokunyibilika okulungileyo kwiintlaka ezahlukeneyo, ngakumbi i-polyurethane resin kunye ne-polyimide resin, kwaye inokusetyenziswa njengesinyibilikisi kwimicu yokwenziwa ekwazi ukumelana nobushushu, iifilimu zeplastiki, izambatho, amayeza, kunye ne-acrylonitrile spinning.I-Dimethylacetamide, njengetyhefu ephantsi, iqondo eliphezulu lokubilisa, kunye ne-polarity ephezulu engeyiyo i-proton solvent kunye ne-chemical intermediate, isetyenziswa ngokubanzi kwimimandla efana nemathiriyeli yokwenziwa, amayeza, izibulali-zinambuzane, imicu yemichiza, ukusetyenzwa kwepetroleum, kunye ne-organic pigments.
Loluphi usetyenziso oluphambili lwe-dimethyl formamide?
01isetyenziswe njenge-reagent yohlalutyo kunye ne-solvent ye-ethylene resin kunye ne-acetylene
02sisinyibilikisi se-organic esigqwesileyo esisetyenziswa njenge-solvent ye-polyurethane, i-polyacrylonitrile, kunye ne-polyvinyl chloride, kunye ne-raw material ye-extractants, amayeza, kunye nezitshabalalisi ezifana nemidacloprid.
03I-Dimethylformamide ayiyona nje into esetyenziswa ngokubanzi yeekhemikhali, kodwa kunye ne-solvent egqwesileyo enoluhlu olubanzi lokusetyenziswa.I-Dimethylformamide iyisisombululo esihle kwiipolymers ezahlukeneyo eziphezulu ezifana ne-polyethylene, i-polyvinyl chloride, i-polyacrylonitrile, i-polyamide, njl.Isetyenziselwa ukwenza ifilimu yeplastiki;Inokusetyenziswa kwakhona njengento yokususa ipeyinti yokususa ipeyinti;Isenokunyibilikisa ii-pigments ezithile ze-solubility ephantsi, ibanike iimpawu zedayi.I-Dimethylformamide isetyenziselwa ukutsalwa kwe-hydrocarbon enevumba elimnandi, kunye nokwahlula kunye nokubuyisela i-butadiene kwiqhezu le-C4 kunye ne-isoprene kwiqhezu le-C5.Isenokusetyenziswa njengesixhobo esisebenzayo sokwahlula amalungu angeyiyo i-hydrocarbon kwiparafini.Inokukhethwa okulungileyo kwi-solubility ye-isophthalic acid kunye ne-terephthalic acid: i-solubility ye-isophthalic acid kwi-dimethylformamide inkulu kune-terephthalic acid.I-solvent extraction okanye i-crystallization eyingxenye kwi-dimethylformamide inokwahlula ezi zimbini.Kwishishini lepetrochemical, i-dimethyl formamide ingasetyenziselwa ukufunxa igesi ukwahlula kunye nokucokisa iigesi.Ekuphenduleni kwezinto eziphilayo, i-dimethylformamide ayisetyenziswanga nje ngokubanzi njenge-solvent, kodwa iyindawo ebalulekileyo ephakathi kwi-organic synthesis.Ingasetyenziselwa ukuvelisa i-chlorpyrifos kwishishini le-pesticide;Kumashishini amayeza, ingasetyenziselwa ukwenza i-pyrimidine iodide, i-doxycycline, i-cortisone, i-vitamin B6, iodoside, i-Qubijing, i-thiapyrimidine, i-N-formyl sarcolysin, i-antineoplastic acid, i-methoxyaromaine, i-bianzapine, i-cyclohexanone i-nitrouran, i-progesterone, i-nitrourane, i-progesterone , biliveratrol, chlorpheniramine, njalo njalo.I-Dimethylformamide idlala indima ebalulekileyo kwi-hydrogenation, dehydrogenation, dehydration, kunye ne-dehalogenation reactions, ukunciphisa ubushushu bokuphendula kunye nokuphucula ukucoceka kwemveliso.
04Isisombululo esingenamanzi se-titration reagent, i-solvent ye-ethylene resin kunye ne-acetylene, i-organic synthesis, i-photometry, i-gas chromatography isigaba sokumisa (ubushushu obuphezulu bokusebenza kwe-50 ℃, i-solvent methanol), ukwahlukana kunye nohlalutyo lwe-hydrocarbons ye-C2-C5, kunye nokukwazi ukwahlula okuqhelekileyo, i-isobutene. , cis, kunye ne trans butene .Uhlalutyo lwentsalela ye-pesticide.Ukuhlanganiswa kwezinto eziphilayo.I-Peptide synthesis.Isetyenziswa kwishishini lokufota.
