Amanyanjana

Acetic acid dimethylacetamide; N, n-dimethylacetamide.

Sebenza

I-DMac isetshenziswa ikakhulukazi njenge-solvent ye-zokwenziwa imicu (i-acrylonitrile) kanye ne-polyurethane spinning and zokwenziwa solvelide resins, futhi isetshenziswa kabanzi kumafilimu we-polymer, futhi isetshenziswa amakhamishini, njll. Isici. Njengamanje, kusetshenziswa kabanzi kwezokwelapha kanye ne-pesticide ukuhlanganisa ama-antibiotics kanye nama-pesticides. Ingasetshenziswa futhi njenge-catalyst yokusabela, i-electrolytic solvent, i-scavenger yokupenda, kanye nezinhlobonhlobo ze-crystalline solvent adverts kanye nezakhiwo eziyizinhlobonhlobo.

Ukufanisa

N, n-dimethylacetamide, eyaziwa nangokuthi i-acetyllimethylamine, noma i-DMac ngamafuphi, iyi-solvent ye-aprotic kakhulu ye-polar enephunga elincane le-ammonia, i-solubity enamandla. Inobuqili kangako ngamanzi, amakhompiyutha amnandi, ama-esters, ama-ketones, ama-alcohols, izibusiso, i-benzene kanye ne-chloroform, ngakho-ke isebenza kusebenze ama-molecule ahlanganisiwe, ngakho-ke isetshenziswa kabanzi njenge-solvent kanye ne-carlyst. Ngokwe-solvent, njenge-solvent enendawo ephezulu yokubila, iphuzu eliphakeme, ukuqina okuphezulu nokuqina kwamakhemikhali, i-vinyl pyrin, i-vinyl pyridine yemvelo kanye namanye ama-copolymers ne-aromatic carboxylic acid solvent; Ngokuya nge-catalyst, ingasetshenziswa kwinqubo yokushisa urea ukukhiqiza i-acid ye-cyanuric, ukusabela kwe-alkyl ne-aletylene ukukhiqiza i-alkyl, kanye nokusabela kwe-organic halide, kanye nokusabela kwe-organic halide kanye ne-clanate ukukhiqiza isocyanate. N, n-dimethylacetamide nayo ingahle isetshenziswe njenge-solvent ye-electrolysis solvent kanye ne-coupler yezithombe, ipende remover, impahla ye-organic synthesis eluhlaza, izinto zokubulala ngezinambuzane kanye nezinto ezibonakalayo zemithi. I-solvent ye-distillact expression yokuhlukanisa i-styrene kusuka kungxenyana ye-C8, njll.
