Acetic acid dimethylacetamide;N, N-Dimethylacetamide.
Ntchito
DMAC zimagwiritsa ntchito monga zosungunulira kwa ulusi kupanga (acrylonitrile) ndi polyurethane kupota ndi kupanga utomoni polyamide, ndipo amagwiritsidwanso ntchito ngati extractive distillation zosungunulira kulekanitsa styrene ku tizigawo C8, ndipo chimagwiritsidwa ntchito polima mafilimu, zokutira ndi mankhwala, etc. mbali.Pakalipano, amagwiritsidwa ntchito kwambiri mu mankhwala ndi mankhwala ophera tizilombo kuti apange maantibayotiki ndi mankhwala ophera tizilombo.Itha kugwiritsidwanso ntchito ngati chothandizira momwe zimachitikira, chosungunulira cha electrolytic, chosungunulira utoto, ndi ma crystalline solvent adducts ndi ma complexes osiyanasiyana.
Kufotokozera
N,N-Dimethylacetamide, yomwe imadziwikanso kuti acetyldimethylamine, acetyldimethylamine, kapena DMAC mwachidule, ndi aprotic kwambiri polar zosungunulira ndi fungo la ammonia pang'ono, kusungunuka kwamphamvu, ndi zinthu zosiyanasiyana zosungunuka.Ndi ambiri miscible ndi madzi, mankhwala onunkhira, esters, ketoni, alcohols, ethers, benzene ndi chloroform, etc., ndipo akhoza yambitsa mamolekyu pawiri, choncho chimagwiritsidwa ntchito monga zosungunulira ndi chothandizira.Pankhani ya zosungunulira, monga zosungunulira ndi mkulu kuwira mfundo, mkulu kung'anima mfundo, mkulu matenthedwe bata ndi kukhazikika mankhwala, angagwiritsidwe ntchito polyacrylonitrile kupota zosungunulira, kupanga utomoni ndi masoka utomoni, vinilu formate, vinilu pyridine ndi copolymers ena ndi Aromatic carboxylic. asidi zosungunulira;ponena za chothandizira, angagwiritsidwe ntchito m`kati Kutentha urea kubala cyanuric asidi, zimene halogenated alkyl ndi zitsulo sianidi kubala nitrile, zimene sodium acetylene ndi halogenated alkyl kubala alkyl alkyne, ndi zochita za organic. halide ndi cyanate kupanga isocyanate.N,N-dimethylacetamide itha kugwiritsidwanso ntchito ngati chosungunulira cha electrolysis zosungunulira ndi zithunzi coupler, utoto remover, organic kaphatikizidwe zopangira, mankhwala ndi mankhwala zopangira.Zosungunulira zosungunulira distillation zolekanitsa styrene ku C8 kachigawo, etc.
