Inkcazo

Igama livela kwinto yokuba yi-Dimyeesyl ye-Fomamide (Amide ye-formic acid), kwaye zombini amaqela e-methyl abekwe kwi-N (i-nitrogen) ye-atom. N, i-N-Dimethylformantuid yi-Polar-Light Holating Holating (i-Hydrophilic) i-Soltitic ye-Amoltic, kunye neekhemikhali inokukhuthaza indlela yokuphendula ye-SN2. N, i-N-Dimethylformasmid iveliswa kusetyenziswa i-formic acid kunye ne-dimthylamine. N, I-N-Dimethylformatid ayizinzanga (ngakumbi kubushushu obuphezulu) phambi kweziseko ezizomeleleyo ezifana ne-slodium hydrockide okanye i-acid eqinileyo njenge-fldrochloric acid kunye ne-dayethylamine. Ihlala izinzile kakhulu emoyeni kwaye xa ifudumele ukubilisa. Xa iqondo lobushushu liphezulu kune-350 ℃, iya kuphulukana namanzi kwaye ivelise i-carbon monoxide kunye ne-dimyerlamine. N, i-n-dimyethylformasmid yindawo elungileyo ye-berotic pollar, enokuphelisa izinto eziphilayo, kwaye zinokuchazwa kwamanzi, i-hydrocarbles, i-earddesbons, i-chaddedic hydrocarbles, njl. Isiphelo esifudumeleyo se-N, N-Dimethylforculamid sijikelezwe ngamaqela e-methyl, senza isithintelo se-steyic, ukuze ii-ion ezimbi azinakusondela, kodwa kuphela ii-ions ezifanelekileyo. I-anaon ye-NAID isebenza ngakumbi kune-anion yenyibilikisiwe. Iindlela ezininzi ze-Ionic zisebenza ngokulula ngakumbi kwi-N, i-N-DimethylforloMforforntuid kunezifihla ze-protic ze-hydrocarbles ezinamaqondo obushushu e-N, N-Dimeethylform I-synthesis yokuthintela i-Esters.
