N,N-Dimethylacetamide CAS: 127-19-5
O mea tau vaila'au: O mea tau vaila'au e tutusa lelei ma le N,N-dimethylformamide, ma o se sui amide solvent. I le leai o se acid po'o le alkali, o le a le pala pe a fa'avevela e fa'apuna i lalo o le mamafa masani, o lea e mafai ai ona fa'amama i lalo o le mamafa masani. Ole fua ole hydrolysis e matua tuai lava. A faʻamafanafanaina le N,N-dimethylacetamide o loʻo i ai le 5% le vai i le 95 ° C mo le 140 itula, naʻo le 0.02% e faʻafefeteina. Ae ui i lea, i le i ai o le gaʻo ma le alkali, e faʻateleina le fua o le hydrolysis. Saponification e tupu pe a vevela i le i ai o se alkali malosi.
O se suavai malamalama maualuga maualuga.
Talosaga fanua
1. Pharmaceutical intermediate dimethylacetamide o se vailaʻau mataʻutia taua ma faʻaaogaina lautele i le gaosiga o le amoxicillin, cephalosporins ma isi vailaʻau. I le avea ai o se solvent poʻo le cocatalyst, e mafai e le dimethylacetamide ona faʻaleleia atili le lelei o oloa ma fua mai pe a faʻatusatusa i vailaʻau masani masani. I le 2000, o le manaʻoga mo le dimethylacetamide i le falemaʻi vailaʻau e tusa ma le 6kt. O le manaʻoga mo le dimethylacetamide i le 2006 e tusa ma le 9.6kt. 2. Fa'apipi'i alava fa'akomepiuta I le gaosiga o alava fa'akomepiuta, o nisi e fa'aogaina le ala o le dimethylacetamide. I le taimi nei, o le gaosiga o fibre acrylic i totonu o le fale Chemicalbook e masani ona aofia ai le sodium thiocyanate auala lua-laasaga, dimethylformamide auala tasi-laasaga ma le dimethylacetamide auala susu susu e tusa ai ma solvents. Mai le vaaiga o le faagasologa ma meafaigaluega uiga, taumafa meafaitino, aafiaga o le siosiomaga, tulaga lelei o oloa, O le tele o mea e pei o le post-processing faatinoga, localization fua faatatau ma faiga atinae mai fafo ua faateleina suesuega talosaga ma taumafaiga faalauiloa. Dimethylacetamide na faʻaaogaina e fai ma faʻatusatusaga atoatoa. Sa fa'aogaina le Sodium thiocyanate auala lua-laasaga ma le dimethylacetamide auala susu. Le atina'e sili ona manuia. I le taimi nei, o le tele o mea faʻapipiʻi fiber acrylic i Saina e faʻaogaina faiga susu e faʻaaoga ai le dimethylacetamide e fai ma solvent.
