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 ngokubanzi kwiifilimu ze-polymer, iingubo kunye namayeza, njl. Okwangoku, 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, iialcohol, i-ethers, ibenzene kunye nekloroform, njl., kwaye inokusebenzisa iimolekyuli ezixubeneyo, ngoko ke isetyenziswa ngokubanzi njenge-solvent kunye ne-catalyst. Ngokumalunga ne-solvent, njenge-solvent enezinga eliphezulu lokubilisa, i-flash point, i-high high stability 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 acid solvent; ngokwemigaqo ye-catalyst, ingasetyenziselwa kwinkqubo yokufudumeza urea ukuvelisa i-cyanuric acid, ukusabela kwe-alkyl ye-halogenated kunye ne-cyanide yensimbi ukuvelisa i-nitrile, ukusabela kwe-acetylene ye-sodium kunye ne-alkyl ye-halogenated ukuvelisa i-alkyl alkyne, kunye nokusabela kwe-halide ye-organic kunye ne-cyanate ukuvelisa i-isocyanate. I-N, i-N-dimethylacetamide ingasetyenziselwa njenge-solvent ye-electrolysis solvent kunye ne-photographic coupler, 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.
