N,N-dimethylformamide bụ mmiri mmiri na-enweghị agba. Enwere ike ịgwakọta ya na mmiri na ọtụtụ ihe mgbaze organic ma e wezụga hydrocarbons halogenated, ọ nwekwara ezigbo mgbaze maka ọtụtụ ihe ndị dị ndụ na ndị na-adịghị ndụ.

N,N-dimethylformamide (DMF) nwere ọtụtụ ojiji, ọkachasị gụnyere akụkụ ndị a:

1. Dị ka ihe mgbaze organic:

DMF bụ ihe mgbaze organic magburu onwe ya nke nwere ike ịgbaze ọtụtụ ihe ndị dị ndụ na ndị na-adịghị ndụ ma nwee ike ịgbaze nke ọma.

N'ime ụlọ ọrụ kemịkalụ polima, a na-eji ya maka ịgbagharị mmiri nke eriri sịntetik dịka eriri polyacrylonitrile, mmepụta nke polyurethanes, na imepụta ihe nkiri plastik.

2. Dị ka ihe eji emepụta kemịkalụ:
DMF bụ ezigbo ihe eji eme ihe n'ọtụtụ mmeghachi omume kemịkalụ, nke nwere ike ibelata okpomọkụ mmeghachi omume ma melite ịdị ọcha nke ngwaahịa ahụ.

N'ime mmepụta ihe ndị sitere n'okike, DMF, dịka ihe dị mkpa n'etiti, na-esonye na mmepụta nke ọtụtụ ihe ndị sitere n'okike.

3. Ngwa n'ime ụlọ ọrụ ọgwụ:
A na-eji DMF emepụta ọtụtụ ọgwụ dị iche iche, dịka iodine pyrimidine, doxycycline, cortisone, wdg.
Ụlọ ọrụ ọgwụ na-ejikarị DMF eme ihe maka mmepụta ọgwụ, karịsịa njikọta nke ụfọdụ molekul organic dị mgbagwoju anya.
;
4. Ngwa ndị ọzọ:
N'ime ụlọ ọrụ eletrọniki, a na-eji DMF emepụta ihe nkiri capacitor na bọọdụ sekit ebipụtara.
A pụkwara iji ya dị ka ihe nyocha, ihe mgbaze maka resin vinyl na acetylene, ihe na-ewepụta ihe, na ihe eji emepụta ọgwụ chlordimeform.
N'ụlọ ọrụ petrochemical, enwere ike iji DMF dị ka ihe na-amịkọrọ gas maka ikewapụ na imezi gas.
