Dimethylformamide (abbreviation DMF), nke a makwaara dị ka N, N-dimethylformamide, bụ ihe nnọchi dimethyl nke foramide, na otu methyl abụọ dị na atọm N (nitrogen), ya mere ọ bụ aha. Dị ka ihe dị mkpa kemịkalụ akụrụngwa na ihe mgbaze dị mma, a na-eji DMF eme ihe na polyurethane, acrylic, ihe mgbakwunye nri, ọgwụ, pesticides, dyes, electronics na ụlọ ọrụ ndị ọzọ.

DMF bụ mmiri mmiri na-enweghị agba na nke na-enweghị atụ nke nwere isi ihe na-esi ísì ụtọ, ebe na-ekpo ọkụ dị ala, ezigbo kemịkalụ na nkwụsi ike nke okpomọkụ, yana mmiri na ọtụtụ ihe mgbaze organic. Ọ bụ ihe mgbaze a na-ejikarị eme ihe maka mmeghachi omume kemịkalụ, a na-akpọkwa ya "ihe mgbaze zuru ụwa ọnụ": A na-eji DMF A na-eji eriri acrylic emepụtara site na usoro akọrọ akọrọ nke ihe mgbaze nke acrylic fiber nwere njirimara nke ezigbo hydrophobicity, ike mkpuchi siri ike, udidi dị nro, na mmetụta aka siri ike; na mmepụta nke mmiri mmiri polyester sịntetik akpụkpọ anụ, DMF nwere ike iji dị ka ihe na-asa na na-agwọ ọrịa maka polyurethane resin. A na-eji ya eme ihe maka mkpuchi ihe dị iche iche a na-atụgharị, na mgbe ejiri akpụkpọ anụ mee ihe, ọ nwere ike ime ka agba nke akpụkpọ anụ akpụkpọ anụ na-adịghị agwụ agwụ; n'ihi ike mgbaze ya siri ike, a na-eji DMF mee ihe dị ka ihe mgbaze na agba agba ma jiri ya mee ihe na-eme ka eriri sịntetị dị nro, nke nwere ike ime ka otu akpụkpọ ahụ dịkwuo mma. Njirimara agba agba; dị ka ihe mgbaze ahọpụtara nke a na-eji na usoro nkewa, DMF nwere ike iji mee ihe maka nnabata nke hydrocarbons dị iche iche na gas inorganic. Dịka ọmụmaatụ, a na-eji DMF na-asa ethylene iji wepụ acetylene, si otú ahụ na-eme ka ethylene dị ọcha. A pụkwara iji DMF wepụ isoprene, piperylene, wdg site na ikuku gas na-emepụta ihe ọkụkụ ethylene maka njikọ nke resin unsaturated; DMF nwekwara ike iji dị ka ihe mgbaze ahọpụtara maka usoro mmịpụta na ngalaba nhazi mmanụ ala. Dịka ọmụmaatụ: na sistemu polycarboxylic acid nke nwere ihe ndị yiri ya ma sie ike ikewa, dị ka isophthalic acid na terephthalic acid, enwere ike kewa ha ngwa ngwa site na mmịpụta ihe mgbaze DMF ma ọ bụ ntughari ntughari.

Na mmeghachi omume organic, ọ bụghị naanị na a na-eji dimethylformamide mee ihe dị ka ihe mgbaze mmeghachi omume, kamakwa ọ bụ etiti dị mkpa na njikọ organic. N'ime ụlọ ọrụ na-emepụta ọgwụ, dị ka onye na-ahụ maka ọgwụ na-emepụta ihe, a na-eji ya eme ihe n'ọtụtụ ebe na mmepụta nke doxycycline, cortisone, na sulfonamide; na ụlọ ọrụ pesticide, a na-eji ya synthesize elu-arụmọrụ na obere-egbu egbu pesticides na ụmụ ahụhụ.

Dị ka mmeghachi omume mmeghachi omume maka njikọ kemịkalụ, DMF nwere ike iji dị ka ihe mgbaze kristal maka sachapụ nke ọgwụ. Na ụlọ ọrụ eletrọnịkị, enwere ike iji ya dozie viscosity nke onye na-agwọ ọrịa maka laminates ọla kọpa. A pụkwara iji DMF mee ihe dị ka ihe mgbaze na-ebu ibu iji mepụta kristal polymeric na BF3 (boron trifluoride), na-eme ka BF3 gbanwee site na gas ka ọ bụrụ ihe siri ike ma dị mfe ibufe. Dị ka ihe mgbaze polar (hydrophilic) aprotic nwere isi ihe na-esi ísì ụtọ, ọ nwere ike ịkwalite usoro mmeghachi omume nucleophilic nucleophilic (SN₂). Na mgbakwunye, dimethylformamide nwere mmetụta catalytic na hydrogenation, dehydrogenation, akpịrị ịkpọ nkụ na mmeghachi omume dehydrohalogenation, nke na-ebelata okpomọkụ mmeghachi omume ma melite ịdị ọcha nke ngwaahịa.

O yiri ka DMF ruru eru maka aha "ihe mgbaze zuru ụwa ọnụ". Ojiji dị iche iche a ga-esi ike karịa n'ime obere oge.
