Mawuno
Acetic acid Dimethylamide; N, N-Dimethlacetamide.
Kugwira nchito
DMAC imagwiritsidwa ntchito ngati zosungunulira chifukwa cha ulusi wopangidwa (acrylonile) ndi polyiredine spinninging ndi styirediide matebulo, ndipo imagwiritsidwanso ntchito ngati mafilimu opanga, zokutira ndi mankhwala osokoneza bongo, etc. Pakadali pano, imagwiritsidwa ntchito kwambiri mu mankhwala ndi mankhwala ophera tizilombo toyambitsa matenda ndi mankhwala ophera tizilombo. Itha kugwiritsidwanso ntchito ngati chothandizira pakuchita, chosungunulira electrolytic, chopanda utoto chopaka, ndi mitundu yosiyanasiyana ya crystalnes ndi ma stages.
Kaonekeswe
N, N-D-Dimethlacetamide, imadziwikanso kuti acetyldimethylamine, acetyldimethylamine, kapena nthawi yochepa kwambiri, ndikusungunuka pang'ono kwa ammoni, komanso zinthu zingapo zosungunuka. Imakhala yolakwika ndi madzi, mankhwala onunkhira, matoto, matontho, mowa, ma chroroform, etc., ndipo imagwiritsidwa ntchito ngati zosungunulira komanso zothandizira. Pankhani yosungunulira, monga solvent ndi malo owiritsa owira, malo owoneka bwino, kukhazikika kwamitundu yambiri komanso kukhazikika kwa polyacrylonine, vinyl pyridic ndi ma carboxylic acid; Pankhani ya chothandizira, itha kugwiritsidwa ntchito potenthetsa urea kuti apange cyanuric acid, zomwe zimachitika alkyl alkyl kuti apange acetyl kuti apange alkyl. N, N-D-Dimethlacetamide amathanso kugwiritsidwa ntchito ngati zosungunulira zamagetsi ndi zojambulajambula, utoto wokhazikika, mankhwala ophera tizilombo. Zotayiratu zosungunulira madzi opanga ma styrene kuchokera ku c8 seraction, etc.
