Basa
DMAC inonyanya kushandiswa sechinhu chinonyungudutsa chesynthetic fibers (acrylonitrile) uye polyurethane spinning uye synthetic polyamide resins, uye inoshandiswawo seyakagadziriswa distillation solvent yekuparadzanisa styrene kubva kuC8 mafraction, uye inoshandiswa zvakanyanya mumafirimu epolymer, machira nemishonga, nezvimwe. .chimiro.Parizvino, inoshandiswa zvakanyanya mukurapa uye mishonga yezvipembenene kugadzira mishonga inorwisa mabhakitiriya nemishonga yezvipembenene.Inogona zvakare kushandiswa sechinhu chinokonzeresa kuita, electrolytic solvent, pendi scavenger, uye akasiyana ecrystalline solvent adducts uye macomplexes.
Tsanangudzo
N,N-Dimethylacetamide, inozivikanwawo seacetyldimethylamine, acetyldimethylamine, kana DMAC kwenguva pfupi, is aprotic yakanyanya polar solvent ine kunhuhwirira kweammonia, kunyungudika kwakasimba, uye huwandu hwezvinhu zvinonyungudika.Inonyanya kusanganiswa nemvura, mishonga inonhuhwirira, esters, ketones, alcohols, ethers, benzene uye chloroform, nezvimwewo, uye inogona kuita kuti mamorekuru emukomboni, saka anoshandiswa zvakanyanya seanonyungudutsa uye catalyst.Panyaya yekunyungudutsa, sechinhu chinonyungudutsa chine yakakwira kubikira poindi, high flash point, high thermal stability and chemical stability, inogona kushandiswa polyacrylonitrile spinning solvent, synthetic resin uye natural resin, vinyl formate, vinyl pyridine nemamwe macopolymers uye Aromatic carboxylic. acid solvent;maererano ne catalyst, inogona kushandiswa mukupisa urea kugadzira cyanuric acid, kuita kwehalogenated alkyl uye metal cyanide kugadzira nitrile, kuita kwesodium acetylene uye halogenated alkyl kugadzira alkyl alkyne, uye maitiro e organic. halide uye cyanate kugadzira isocyanate.N,N-dimethylacetamide inogonawo kushandiswa sechinhu chinonyungudutsa che electrolysis solvent uye photographic coupler, pendi inobvisa, organic synthesis raw material, pesticide uye mishonga mbishi.Extractive distillation solvent yekuparadzanisa styrene kubva kuC8 chidimbu, nezvimwe.
