Shaqada
DMAC waxaa inta badan loo isticmaalaa sida dareere loogu talagalay fiilooyinka synthetic (acrylonitrile) iyo poliurethane spinning iyo polyamide synthetic polyamide, sidoo kale waxaa loo isticmaalaa sida dareeraha distillation soo saarista ee kala sooca styrene iyo jajabyada C8, waxaana si weyn loogu isticmaalaa filimada polymer, dahaarka iyo daawooyinka, iwm dhinac.Waqtigan xaadirka ah, waxaa si weyn loogu isticmaalaa daawada iyo sunta cayayaanka si loo soo saaro antibiyootiga iyo sunta cayayaanka.Waxa kale oo loo isticmaali karaa kicinta fal-celinta, dareeraha korantada, dareeraha rinjiga, iyo noocyada kala duwan ee dareeraha dareeraha crystalline.
Sharaxaada
N, N-Dimethylacetamide, oo sidoo kale loo yaqaan acetyldimethylamine, acetyldimethylamine, ama DMAC gaaban, waa dareere aprotic ah oo aad u sarreeya oo leh ur ammonia yar, milmayn xoog leh, iyo noocyo kala duwan oo walxaha milmaya.Waa mid si weyn u qallafsan biyaha, xeryahooda udgoon, esters, ketones, alcohols, ethers, benzene iyo chloroform, iwm.Marka la eego dareeraha, sida dareere leh barta karkarinta sare, dhibic sare, xasilloonida kuleylka sare iyo xasilloonida kiimikada, waxaa loo isticmaali karaa dareeraha lafdhabarta polyacrylonitrile, resin synthetic iyo resin dabiiciga ah, vinyl formate, vinyl pyridine iyo copolymers kale iyo carboxylic caraf udgoon. dareere acid;Marka la eego kicinta, waxaa loo isticmaali karaa habka kululaynta urea si loo soo saaro cyanuric acid, falcelinta alkyl halogenated iyo cyanide birta si ay u soo saaraan nitrile, falcelinta sodium acetylene iyo alkyl halogenated si ay u soo saaraan alkyl alkyne, iyo falcelinta organic halide iyo cyanate si ay u soo saaraan isocyanate.N, N-dimethylacetamide waxa kale oo loo isticmaali karaa sida dareere loogu talagalay dareeraha korantada iyo sawir-qaadayaasha sawir-qaadista, rinjiga ka saara, walxo cayriin ah oo isku dhafan, sunta cayayaanka iyo alaabta ceeriin ee daawada.Kala saarista styrene ee jajabka C8, iwm.
