99.9 feem pua Dimethyl acetamide
Dimethylacetamide (DMAC los yog DMA) yog cov organic compound nrog cov mis CH3C(O)N(CH3)2. Qhov no tsis muaj xim, dej-miscible, cov kua kub kub yog feem ntau siv los ua cov kuab tshuaj polar hauv cov organic synthesis. DMA yog miscible nrog rau feem ntau lwm cov kuab tshuaj, txawm hais tias nws tsis zoo soluble nyob rau hauv aliphatic hydrocarbons.

Daim ntawv thov
1) Cov kuab tshuaj zoo polar siv los ua raw khoom rau hluavtaws fibers thiab organic synthesis
2) Organic synthesis, kuj siv los ua hnyav, catalyst thiab xim tshem tawm
3) Kev siv DMAC feem ntau yog siv los ua hluavtaws fiber ntau (acrylonitrile) thiab polyurethane spinning thiab hluavtaws polyamide resin yog siv rau hnyav, extractive distillation hnyav cais styrene los ntawm C8 feem, thiab yog dav siv nyob rau hauv polymer films, coatings thiab lwm yam.
4) Siv rau cov synthesis ntawm reactive solvents, hluavtaws fiber ntau spinning thiab hluavtaws resin hnyav, hnyav, xim, thiab lwm yam.
