Tom ntej: Dimethylacetamide DMAC CAS 127-19-5yog xim tsis muaj xim, siab - boiling, polar, hygroscopic kua. Dimethylacetamide DMAC yog cov kuab tshuaj zoo rau ntau yam organic thiab inorganic tebchaw thiab yog miscible nrog dej, ethers, esters, ketones, thiab aromatic compounds. Nws yog siv los tsim cov polyacrylonitrile thiab polyurethane-raws li fibers, films, thiab coatings. Lub ncov qaumteb qabteb ntawm Dimethylacetamide DMAC ua rau nws ua raws li cov kuab tshuaj thiab cov tshuaj tiv thaiv catalyst nyob rau hauv ntau cov txheej txheem, yielding siab -purity khoom nrog high yields nyob rau hauv luv luv cov tshuaj tiv thaiv lub sij hawm.
Kev siv qib DMAC:
CAS 127-19-5 Dimethylacetamide (DMAC) yog dipolar aprotic hnyav siv rau ntau cov tshuaj tiv thaiv organic thiab kev siv hauv kev lag luam. Nws yog ntau yam hnyav hnyav vim nws qhov kub kub taw tes thiab zoo thermal thiab tshuaj stability.
1. Acrylic fibers: DMAC yog siv los ua cov kuab tshuaj hauv cov txheej txheem ntub dej rau kev tsim cov acrylic fibers.
2. Elasthane fibers: Dimethylacetamide yog cov khoom hnyav tshaj plaws rau kev tsim cov polyurethane-basedelasthane fibers, muab nws cov evaporation ceev, txawm tias nws yog siv rau hauv cov txheej txheem ntub dej los yog qhuav spinning.
3. Pharmaceuticals: DMAC tuaj yeem siv los ua cov kuab tshuaj thiab cov tshuaj reagent hauv kev tsim khoom ntawm ntau yam tshuaj. Nws yog siv rau hauv kev tsim cov txheej txheem ntawm cephalosporins, uas yog ib qho ntawm cov chav kawm ntawm cov tshuaj tua kab mob.
4. Ntau yam polymers: N, N-Dimethylacetamide yog cov kuab tshuaj zoo rau polyimide resins, ob qho tib si hauv txheej txheej thiab ua yeeb yaj kiab. Nws kuj yog qhov zoo tagnrho hnyav rau kev tsim cov dialyser membranes, raws li polysulfones. Kev sib xyaw ntawm DMAC thiab lithium chloride yog ib qho hnyav hnyav rau cellulose fibers hauv ntau daim ntawv thov.
