Izithethantonye
I-acetic acid dimethylacetamide;N, N-Dimethylacetamide.
Umsebenzi
I-DMAC isetyenziswa ikakhulu njengesinyibilikisi semicu yokwenziwa (acrylonitrile) kunye ne-polyurethane spinning kunye ne-synthetic polyamide resins, kwaye ikwasetyenziswa njenge-extractive distillation solvent yokwahlula i-styrene kumaqhezu e-C8, kwaye isetyenziswa kakhulu kwiifilimu ze-polymer, iingubo kunye namayeza, njl. inkaloOkwangoku, isetyenziswa kakhulu kumayeza kunye ne-pesticide ukwenza i-antibiotics kunye ne-pesticides.Isenokusetyenziswa njenge-catalyst ye-reaction, i-solvent electrolytic, i-scavenger yepeyinti, kunye neentlobo ezahlukeneyo ze-crystalline solvent adducts kunye ne-complex.
Inkcazo
I-N, N-Dimethylacetamide, eyaziwa ngokuba yi-acetyldimethylamine, i-acetyldimethylamine, okanye i-DMAC ngokufutshane, i-aprotic i-solvent ephezulu ye-polar enevumba elincinane le-ammonia, ukunyibilika okunamandla, kunye noluhlu lwezinto ezinyibilikayo.Ixutywa ngokubanzi ngamanzi, iikhompawundi ezinuka kamnandi, ii-esters, iiketoni, iialkoholi, i-ethers, ibenzene kunye nekloroform, njl., kwaye inokwenza iimolekyuli ezihlanganisiweyo zisebenze, ngoko ke isetyenziswa ngokubanzi njengenyibilikisi kunye ne-catalyst.Ngokumalunga ne-solvent, njenge-solvent enezinga eliphezulu lokubilisa, i-flash point ephezulu, ukuzinza okuphezulu kwe-thermal kunye nokuzinza kweekhemikhali, ingasetyenziselwa i-polyacrylonitrile spinning solvent, i-synthetic resin kunye ne-resin yendalo, i-vinyl formate, i-vinyl pyridine kunye nezinye i-copolymers kunye ne-Aromatic carboxylic. isinyibilikisi seasidi;ngokwemiqathango ye-catalyst, ingasetyenziselwa kwinkqubo yokufudumeza urea ukuvelisa i-cyanuric acid, ukusabela kwe-alkyl ye-halogenated kunye ne-cyanide yesinyithi ukuvelisa i-nitrile, ukusabela kwe-acetylene ye-sodium kunye ne-alkyl ye-halogenated ukuvelisa i-alkyl alkyne, kunye nokuphendula kwezinto eziphilayo. i-halide kunye ne-cyanate ukuvelisa i-isocyanate.I-N, i-N-dimethylacetamide ingasetyenziselwa njenge-solvent ye-electrolysis solvent kunye ne-coupler yezithombe, i-remover yepeyinti, i-organic synthesis ekrwada, i-pesticide kunye ne-pharmaceutical raw material.I-solvent yokukhupha i-distillation yokwahlula i-styrene kwiqhezu le-C8, njl.
