Galuega
O le DMAC e masani ona faʻaaogaina e avea o se solvent mo filo faʻapipiʻi (acrylonitrile) ma polyurethane spinning ma synthetic polyamide resins, ma e faʻaaogaina foi e avea o se solvent distillation extractive mo le vavaeeseina o styrene mai vaega C8, ma e faʻaaogaina lautele i polymer films, coatings ma pharmaceuticals, etc. .ituaiga.I le taimi nei, o loʻo faʻaaogaina lautele i vailaʻau ma vailaʻau e faʻapipiʻi ai vailaau faʻamaʻi ma vailaau faʻasaina.E mafai foʻi ona faʻaaogaina e fai ma faʻalavelave mo le tali atu, o se solvent electrolytic, se vali vali, ma le tele o mea faʻapipiʻi faʻapipiʻi tioata ma faʻalavelave.
Fa'amatalaga
N,N-Dimethylacetamide, e taʻua foi o le acetyldimethylamine, acetyldimethylamine, poʻo le DMAC mo se faʻapuupuu, o se solu polar aprotic ma sina manogi ammonia, malosi solubility, ma le tele o mea soluble.E faʻafefiloi lautele i vai, mea manogi manogi, esters, ketones, alcohols, ethers, benzene ma chloroform, ma isi, ma e mafai ona faʻagaoioia mole faʻapipiʻi, o lea e faʻaaogaina lautele o se solvent ma catalyst.E tusa ai ma le solvent, e pei o se solvent ma le maualuga o le vevela, maualuga le moli, maualuga le vevela ma le mautu vailaʻau, e mafai ona faʻaaogaina mo le polyacrylonitrile spinning solvent, resin synthetic ma resin natura, vinyl formate, vinyl pyridine ma isi copolymers ma Aromatic carboxylic so'o so'o;i le tulaga o le catalyst, e mafai ona faaaogaina i le faagasologa o le vevela urea e maua ai le cyanuric acid, o le tali o halogenated alkyl ma metal cyanide e maua ai nitrile, o le tali o le sodium acetylene ma halogenated alkyl e maua ai alkyl alkyne, ma le tali o organic. halide ma cyanate e maua ai le isocyanate.N, N-dimethylacetamide e mafai foi ona faʻaaogaina e avea o se solvent mo le electrolysis solvent ma le faʻapipiʻi ata, vali vali, mea faʻapipiʻi faʻasolosolo, vailaʻau faʻamaʻi ma vailaʻau.Soli fa'amama fa'ameamea mo le tu'u'ese'ese o le styrene mai le vaega C8, ma isi.
