I-Dimethylformamide (isifinyezo se-DMF), ekwaziwa ngokuba yi-N,N-dimethylformamide, yindawo ye-dimethylformamide, kwaye omabini amaqela e-methyl abekwe kwi-athomu ye-N (nitrogen), ngoko ke ligama. Njengomathiriyeli obalulekileyo weekhemikhali kunye ne-solvent esebenza ngokugqwesileyo, i-DMF isetyenziswa ngokubanzi kwi-polyurethane, i-acrylic fiber, izongezo zokutya, amayeza, izitshabalalisi, idayi, i-elektroniki kunye namanye amashishini.

I-DMF ilulwelo olungenambala noluselubala olunendawo yokubilisa ephezulu, indawo ephantsi yokukhenkceza, ikhemikhali elungileyo kunye nokuzinza kwe-thermal, kwaye iyaxubana namanzi kunye nezona zinyibilikisiweyo zininzi. Yinto esetyenziswa ngokuqhelekileyo kwi-solvent ye-chemical reactions kwaye ibizwa ngokuba "i-solvent jikelele": i-DMF isetyenzisiweyo I-fiber ye-acrylic eveliswa yinkqubo eyomileyo yokujikeleza ye-solvent-based acrylic fiber ineempawu ze-hydrophobicity enhle, amandla okugquma anamandla, ukuthungwa okuthambileyo, kunye nokuziva isandla esomeleleyo; kwimveliso yesikhumba se-polyester emanzi, i-DMF ingasetyenziselwa ukuhlamba kunye nokunyanga i-polyurethane resin. Isetyenziselwa ukugquma izinto ezahlukeneyo ezandisiweyo, kwaye xa isetyenziselwa ukudaya kwesikhumba, inokwenza umbala weyunifomu yesikhumba kwaye ungapheli; ngenxa yesakhono esinamandla sokunyibilika, iDMF isetyenziselwa ukunyibilikisa kwidayi kwaye isetyenziselwa ukudaya iintsinga zokwenziwa, ezinokuphucula ukufana kwesikhumba. Iimpawu zokudaya; njenge-solvent ekhethiweyo esetyenziswa kwiinkqubo zokwahlula, i-DMF ingasetyenziselwa ukunyuswa okukhethiweyo kwee-hydrocarbons ezahlukeneyo kunye neegesi ze-inorganic. Ngokomzekelo, i-DMF isetyenziselwa ukuhlamba i-ethylene ukususa i-acetylene, ngaloo ndlela ihlambulula i-ethylene. I-DMF ingasetyenziselwa ukukhupha i-isoprene, i-piperylene, njl njl kwi-gas yokukhupha i-ethylene plant production for synthesis of unsaturated resin; I-DMF isenokusetyenziswa njengesinyibilikisi esikhethiweyo kwiinkqubo zokutsalwa kwintsimi yepetroleum processing. Umzekelo: kwiinkqubo ze-polycarboxylic acid ezineepropati ezifanayo kwaye kunzima ukuhlukana, njenge-isophthalic acid kunye ne-terephthalic acid, ziyakwazi ukuhlukana ngokulula nge-DMF ye-solvent extraction okanye i-stepwise recrystallization.

Ekuphenduleni kwezinto eziphilayo, i-dimethylformamide ayisetyenziswanga ngokubanzi njenge-solvent yokuphendula, kodwa iyindawo ebalulekileyo ephakathi kwi-organic synthesis. Kwishishini lamachiza, njengeyeza eliphakathi, lisetyenziswa kakhulu kwimveliso ye-doxycycline, i-cortisone, kunye ne-sulfa drug; kushishino lwezitshabalalisi, isetyenziselwa ukudibanisa imichiza esebenza ngokufanelekileyo kunye nenetyhefu ephantsi.

Njengendlela yokusabela kwi-chemical synthesis, i-DMF ingasetyenziselwa njenge-solvent ye-crystallization yokuhlanjululwa kwamayeza. Kwishishini le-elektroniki, lingasetyenziselwa ukulungelelanisa i-viscosity ye-agent ephilisayo ye-laminates yobhedu. I-DMF ingasetyenziselwa njenge-solvent ye-carrier ukuze yenze i-polymeric crystal kunye ne-BF3 (i-boron trifluoride), eyenza i-BF3 itshintshe ukusuka kwigesi ukuya eqinile kwaye kulula ukuyihambisa. Njenge-polar (hydrophilic) i-solvent ye-aprotic enendawo ephezulu yokubilisa, inokukhuthaza i-bimolecular nucleophilic substitution reaction (SN₂) indlela. Ukongezelela, i-dimethylformamide inempembelelo ye-catalytic kwi-hydrogenation, i-dehydrogenation, i-dehydration kunye ne-dehydrohalogenation reactions, eyanciphisa ukushisa kwe-reaction kunye nokuphucula ukucoceka kwemveliso.

Kubonakala ngathi i-DMF ifanelekile kwisihloko esithi "i-solvent jikelele". Olu hlobo losetyenziso luya kuba nzima ukugqwesa ngexesha elifutshane. Inkampani yethu ikwinqanaba eliphezulu kushishino ngokwamandla enkampani, umthamo wemveliso yeDMF, umgangatho wemveliso, kunye nodumo lophawu. Siziqhelanisa nokhetho lokuqala lomthengi kwaye sikukhonze ngentliziyo epheleleyo.
