Omqondofana
I-acetic acid dimethylacetamide;N, N-Dimethylacetamide.
Umsebenzi
I-DMAC isetshenziswa kakhulu njengesinyibilikisi semicu yokwenziwa (i-acrylonitrile) kanye ne-polyurethane spinning kanye ne-synthetic polyamide resins, futhi isetshenziswa njengesixazululi se-distillation esikhiphayo sokuhlukanisa i-styrene kuma-fractions e-C8, futhi isetshenziswa kakhulu kumafilimu e-polymer, izintambo kanye nemithi, njll. isici.Njengamanje, isetshenziswa kabanzi kwezokwelapha kanye nezibulala-zinambuzane ukuze kuhlanganiswe ama-antibiotic kanye nezibulala-zinambuzane.Ingasetshenziswa futhi njenge-catalyst yokusabela, i-solvent electrolytic, i-scavenger kapende, kanye nezinhlobonhlobo ze-crystalline solvent adducts nama-complexes.
Incazelo
I-N,N-Dimethylacetamide, eyaziwa nangokuthi i-acetyldimethylamine, i-acetyldimethylamine, noma i-DMAC ngamafuphi, iyincibilikisi epholile epholile ene-aprotic enephunga elincane le-ammonia, ukunyibilika okuqinile, kanye nohlu lwezinto ezincibilikayo.Ixubene kakhulu namanzi, izinhlanganisela ezinuka kamnandi, ama-ester, ama-ketone, ama-alcohol, ama-ether, i-benzene ne-chloroform, njll., futhi ingenza kusebenze ama-molecule ayinhlanganisela, ngakho-ke isetshenziswa kabanzi njenge-solvent kanye ne-catalyst.Ngokuya nge-solvent, njenge-solvent enephuzu eliphezulu lokubilisa, i-flash point, ukuzinza okuphezulu kokushisa kanye nokuzinza kwamakhemikhali, ingasetshenziselwa i-polyacrylonitrile spinning solvent, i-synthetic resin ne-resin yemvelo, i-vinyl formate, i-vinyl pyridine namanye ama-copolymers kanye ne-Aromatic carboxylic. i-asidi encibilikayo;mayelana ne-catalyst, ingasetshenziswa ekushiseni i-urea ukukhiqiza i-cyanuric acid, ukusabela kwe-alkyl e-halogenated ne-cyanide yensimbi ukukhiqiza i-nitrile, ukusabela kwe-sodium acetylene kanye ne-halogenated alkyl ukukhiqiza i-alkyl alkyne, kanye nokusabela kwe-organic. i-halide ne-cyanate ukukhiqiza isocyanate.I-N,N-dimethylacetamide ingasetshenziswa futhi njengesinyibilikisi se-electrolysis solvent kanye ne-coupler yezithombe, isikhiphi sikapende, i-organic synthesis raw material, isibulala-zinambuzane kanye nempahla eluhlaza yemithi.I-solvent ye-distillation ekhishwayo yokuhlukanisa i-styrene nengxenye ye-C8, njll.
