I-N,N-Dimethylformamide CAS 68-12-2
I-Dimethylformamide lulwelo olungenambala nolucacileyo. Ayisiyonto nje kuphela esetyenziswa kakhulu ngamakhemikhali, kodwa ikwasisinyibilikisi esibalaseleyo esinoluhlu olubanzi lokusetyenziswa. I-Dimethylformamide yinto ebalulekileyo esetyenziswa kumayeza, iikhemikhali, ulusu kunye neminye imimandla.
I-Dimethylformamide ibizwa ngokuba yi-DMF. Yikhompawundi apho iqela le-hydroxyl le-formic acid lithathelwa indawo liqela le-dimethylamino, elinefomula yemolekyuli i-HCON(CH3)2. Lulwelo olungenambala nolucacileyo olune-high-boiling point olunevumba elincinci le-amine kunye noxinano oluhambelanayo lwe-0.9445 (25℃). Inqanaba lokunyibilika -61℃. Inqanaba lokubila 152.8℃. Inqanaba lokutsha 57.78℃. Uxinano lomphunga 2.51. Uxinzelelo lomphunga 0.49kpa (3.7mmHg25℃). Inqanaba lokutsha liyi-445℃. Umda wokuqhuma komxube womphunga nomoya yi-2.2~15.2%. Ukuvezwa kumlilo ovulekileyo kunye nobushushu obuphezulu kunokubangela ukutsha kunye nokuqhuma. Ingasabela ngamandla nge-sulfuric acid exineneyo kunye ne-fuming nitric acid kwaye ide iqhume. Ixutywa namanzi kunye nezinye izinyibilikisi ze-organic Chemicalbook. Yi-solvent eqhelekileyo kwiimpendulo zeekhemikhali. I-dimethylformamide ecocekileyo ayinavumba, kodwa i-dimethylformamide yodidi lweshishini okanye eyonakeleyo inevumba elifana nelentlanzi kuba iqulethe ukungcola kwe-dimethylamine. Eli gama livela kwinto yokuba iyindawo ye-dimethyl endaweni ye-formamide (i-amide ye-formic acid), kwaye omabini amaqela e-methyl akwi-atom ye-N (nitrogen). I-Dimethylformamide sisinyibilikisi se-polar (hydrophilic) aprotic esineqondo lokubila eliphezulu, esinokukhuthaza indlela yokusabela ye-SN2. I-Dimethylformamide yenziwe nge-formic acid kunye ne-dimethylamine.
