He wai moakaka kala ʻole ka N,N-dimethylformamide. Hiki ke kāwili ʻia me ka wai a me ka hapa nui o nā mea hoʻoheheʻe organik koe wale nō nā hydrocarbons halogenated, a he solubility maikaʻi no nā ʻano hui organik a me inorganic.

He nui nā hoʻohana o N,N-dimethylformamide (DMF), ʻo ia hoʻi nā ʻano aʻe:

1. Ma ke ʻano he mea hoʻoheheʻe organik:

He mea hoʻoheheʻe organik maikaʻi loa ʻo DMF i hiki ke hoʻoheheʻe i nā ʻano mea like ʻole o nā mea organik a me nā mea inorganic a he solubility ikaika kona.

I loko o ka ʻoihana kemika polymer, hoʻohana ʻia no ka milo pulu o nā olonā synthetic e like me nā olonā polyacrylonitrile, synthesis o polyurethanes, a me ka hana ʻana i nā kiʻiʻoniʻoni plastic.

2. Ma ke ʻano he mea maka kemika:
He mea hoʻomehana maikaʻi loa ʻo DMF i nā hopena kemika he nui, hiki ke hoʻemi i ka mahana o ka hopena a hoʻomaikaʻi i ka maʻemaʻe o ka huahana.

I ka synthesis organik, ʻo DMF, ma ke ʻano he waena koʻikoʻi, ke komo nei i ka synthesis o nā ʻano hui organik like ʻole.

3. Hoʻohana ʻia ma ka ʻoihana lāʻau lapaʻau:
Hoʻohana ʻia ka DMF e hana i nā ʻano lāʻau like ʻole, e like me ka iodine pyrimidine, doxycycline, cortisone, etc.
Hoʻohana pinepine ka ʻoihana lāʻau lapaʻau i ka DMF no ka hana ʻana i nā lāʻau lapaʻau, ʻoiai ka hana ʻana o kekahi mau molekala organik paʻakikī.
?
4. Nā noi ma nā kahua ʻē aʻe:
I ka ʻoihana uila, hoʻohana ʻia ʻo DMF e hana i nā kiʻiʻoniʻoni capacitor a me nā papa kaapuni i paʻi ʻia.
Hiki ke hoʻohana ʻia ma ke ʻano he reagent analytical, kahi solvent no nā resins vinyl a me acetylene, kahi extractant, a me kahi mea maka no ka pesticide chlordimeform.
I ka ʻoihana petrochemical, hiki ke hoʻohana ʻia ʻo DMF ma ke ʻano he mea hoʻopū kinoea no ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i nā kinoea.
