Isicelo
Ulwelo olungenambala olucacileyo okanye olutyheli olukhanyayo olunevumba lentlanzi
1. Yinto egqwesileyo ye-organic solvent, esetyenziswa njenge-solvent ye-polyurethane, i-polyacrylonitrile, kunye ne-polyvinyl chloride.Ikwasetyenziswa njengemathiriyeli ekrwada kwi-extractants, amayeza kunye nezitshabalalisi.
2. Isetyenziswe njenge-reagent yokuhlalutya kunye ne-solvent ye-vinyl resin kunye ne-acetylene
3. I-Dimethylformamide ayisiyiyo kuphela imveliso yeekhemikhali esebenza ngeendlela ezininzi, kodwa kunye ne-solvent egqwesileyo esebenza ngeendlela ezininzi.I-Dimethylformamide i-solvent efanelekileyo kwiindidi ze-polymers ezifana ne-polyethylene, i-polyvinyl chloride, i-polyacrylonitrile, i-polyamide, njl., kwaye ingasetyenziselwa ukujikeleza okumanzi kwee-synthetic fibers ezifana ne-polyacrylonitrile fiber, kunye ne-synthesis ye-polyurethane;Isetyenziselwa ukwenza ifilimu yeplastiki;inokusetyenziswa njengesixhobo sokususa ipeyinti ukususa ipeyinti;inokunyibilikisa ezinye ii-pigments ezinyibilikayo ezisezantsi, zinike ii-pigments iimpawu zedayi.I-Dimethylformamide isetyenziselwa ukukhutshwa kwe-aromatics kunye nokwahlula kunye nokubuyiselwa kwe-butadiene kwi-C4 iqhezu kunye ne-isoprene kwi-C5 iqhezu.Isenokusetyenziswa njengesixhobo esisebenzayo sokwahlula amacandelo angeyo-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-Chemicalbook yenza i-solvent extraction okanye i-crystallization ye-partial inokwahlula ezimbini.Kwishishini le-petrochemical, i-dimethylformamide ingasetyenziselwa i-gas absorbent ukwahlula kunye nokucokisa igesi.Ekuphenduleni kwezinto eziphilayo, i-dimethylformamide ayisetyenziswanga ngokubanzi njenge-solvent ye-reaction, kodwa kunye ne-intermediate ebalulekileyo kwi-organic synthesis.Kwishishini lokubulala izitshabalalisi, inokusetyenziselwa ukuvelisa izibulali-zinambuzane;kwishishini lamachiza, ingasetyenziselwa ukwenza iodosamine, doxycycline, cortisone, vitamin B6, iodoside, ququjing, pyrantel, N-formyllysar Onumaric acid, methoxy mustard, chlorambucil, nitrosourea, furfurouracil, tranexamic, chooretha, feges, feges i-chlorpheniramine, njl. I-Dimethylformamide inempembelelo ye-catalytic kwiimpendulo ze-hydrogenation, i-dehydrogenation, i-dehydration kunye ne-dehydrohalogenation, eyanciphisa ubushushu bokuphendula kunye nokuphucula ukucoceka kwemveliso.
4.I-Titration yezinyibilikisi ezingenamanzi.I-solvent ye-vinyl resin kunye ne-acetylene.Ukuzimisela kweFotometric.Ulwelo olumileyo lwerhasi yechromatographic (ubushushu obona buninzi buyi-50 ℃, i-solvent yi-methanol), i-Chemicalbook eyahlukileyo ukuhlalutya i-C2-C5 hydrocarbons, kwaye inokwahlula eqhelekileyo kunye ne-isobutene kunye ne-cis kunye ne-trans-2-butene.Uhlalutyo lweentsalela zezibulali zinambuzane.I-Organic Synthesis.Ukwenziwa kweepeptides.Kushishino lweefoto.
