N, N-Dimethylacetamide (DMAc) CAS 127-19-5 Purity ≥99.80% (GC) Hoobkas

N, N-Dimethylacetamide (DMAc) (CAS: 127-19-5) yog ib qho polar aprotic hnyav heev, micro ammonia tsw, muaj zog dissolving zog, soluble dav, miscible nrog dej, aromatics, esters, ketones, cawv, ether, benzene thiab chloroform thiab lwm yam arbitrary thiab pab kom ua kom cov tebchaw molecular.Nws yog dav siv los ua cov kuab tshuaj thiab cov catalyst.Cov kuab tshuaj, nrog kub kub taw tes, flash point, thermal stability thiab tshuaj stability ntawm cov kuab tshuaj, yog siv rau polyacrylonitrile spinning hnyav, hluavtaws resin thiab ntuj resins, formic acid vinyl ester resin, vinyl pyridine copolymer thiab aromatic carboxylic acid.Cov catalyst tuaj yeem siv rau hauv cov txheej txheem ntawm urea cua sov los tsim cov tshuaj tiv thaiv ntawm cyanide, sodium halide thiab hlau cyanide los tsim cov tshuaj tiv thaiv ntawm alkyl acetylene, organic halide thiab isocyanate.N, N-Dimethylacetamide kuj tuaj yeem siv los ua cov kuab tshuaj electrolytic thiab thaij duab nrog cov kuab tshuaj sib tov, cov tshuaj pleev xim, cov organic synthesis ntawm raw cov ntaub ntawv, tshuaj tua kab thiab tshuaj raw cov ntaub ntawv.Kev sib cais ntawm styrene los ntawm C8 feem, rho tawm, distillation, hnyav, thiab lwm yam.
N, N-Dimethylacetamide yog siv los ua cov kuab tshuaj tiv thaiv kab mob hauv cov organic synthesis nrog rau cov tshuaj tiv thaiv muaj zog xws li sodium hydroxide.Nws kuj yog siv los ua cov kuab tshuaj rau cov fibers xws li polyacrylonitrile, spandex, raws li ib tug excipient hauv tshuaj viz.vumon, busulfex thiab hauv kev lag luam nplaum.Nws pom daim ntawv thov ua cov tshuaj tiv thaiv nruab nrab hauv kev tsim tshuaj, agrochemicals, dyes thiab plasticizers.Nws yog dav siv hauv kev lag luam polymer vim nws lub zog daws teeb meem rau siab molecular-yuag polymers thiab hluavtaws cob.Nws plays lub luag hauj lwm tseem ceeb raws li ib tug catalyst nyob rau hauv ntau yam tshuaj tiv thaiv viz.cyclization, halogenation, cynidation, alkylation thiab dehydrogenation thiab tsub kom cov qoob loo ntawm cov khoom tseem ceeb.Nws kuj yog siv los ua tus neeg sawv cev rau cov roj thiab roj, hauv cov xim tshem tawm, hauv kev tsim cov duab-tiv thaiv stripping tebchaw thiab ua cov tshuaj hnyav hauv cov txheej txheem.
DMAc yog cov khoom siv hluavtaws uas tsim los ntawm cov tshuaj tiv thaiv ntawm dimethylamine thiab acetic acid lossis acetic anhydride.DMAc feem ntau cuam tshuam nrog ntau qhov kev siv hauv kev lag luam, xws li cov khoom pib lossis qhov nruab nrab.DMAc yog cov kuab tshuaj zoo uas yog siv rau hauv kev sib cais polymer, tshwj xeeb tshaj yog nyob rau hauv kev lag luam fiber ntau.
N, N-Dimethylacetamide yog cov kuab tshuaj zoo heev thiab feem ntau ua raws li cov khoom siv hauv halogenation, cyclization, thiab alkylation cov tshuaj tiv thaiv.Nws yog ib qho tseem ceeb muaj kuab tshuaj rau polyacrylonitrile, vinyl resins, cellulose derivatives, styrene polymers thiab linear polyesters.Nws kuj yog siv nyob rau hauv tag nrho cov analytical Laboratories raws li ib tug loj feem ntawm mobile theem nyob rau hauv High Performance Liquid Chromatography (HPLC) thiab nyob rau hauv Kua Chromatography - Mass Spectrometry (LC-MS).N, N-dimethylacetamide lithium chelate complexes intercalate cationic sites hauv txheej silicates.
N, N-Dimethylacetamide feem ntau yog siv los ua cov kuab tshuaj thiab nruab nrab hauv kev tsim cov tshuaj, tshuaj zoo, agrochemicals, polymers, thiab resins.Nws kuj yog siv los ua cov kuab tshuaj spinning hauv kev tsim cov fibers ntawm ntau yam polymers, xws li acrylic, polyurethane, polyurea copolymer, thiab meta-aramid.Ntxiv mus, no aprotic dipolar hnyav kuj yog siv nyob rau hauv X-ray thiab yees duab cov khoom thiab nyob rau hauv zus tau tej cov polyimide films.
