Tom ntej: Dimethylacetamide CAS 127-19-5yog dav siv nyob rau hauv kev tsim tshuaj vim nws yog ib tug siab - boiling, heev polar aprotic solvent uas yuav yaj nyuaj raw cov ntaub ntawv thiab txhawb cov tshuaj muaj txiaj ntsig zoo.
Dimethylacetamide (CAS 127-19-5) yog dab tsi?
N,N-Dimethylacetamide (DMAC) yog xim tsis muaj xim, siab-boiling-point hnyav siv dav hauv ntau cov txheej txheem tsim khoom, suav nrog kev tsim cov khoom siv hluavtaws, yas, tshuaj, thiab khoom siv hluav taws xob. Nws cov qauv tshuaj yog C4H9NO, thiab nws tus lej CAS yog 127-19-5.
Cov khoom ntawm N, N-Dimethylacetamide:
DMAC yog cov kuab tshuaj polar, miscible nrog dej, cawv, ethers, thiab ntau cov kuab tshuaj organic. Nws cov ntsiab lus kub kub yog siab, ntawm 165-166 degree, ua rau nws haum rau siab - kub thiab distillation. Dimethylacetamide DMAC muaj qhov tsis muaj vapor siab thiab tsis yog -flammable thiab tsis tawg. Nyob rau hauv ib txwm kub thiab siab, DMAC yog ruaj khov, tab sis nws decomposes nyob rau hauv lub xub ntiag ntawm muaj zog acids los yog bases.
Yuav Siv Dimethylacetamide hnyav li cas hauv Kev Tsim Tshuaj?
Polymer thiab High -Cov Khoom Siv Ua Haujlwm Zoo
Qhov no yog daim ntawv thov loj tshaj plaws rau Dimethylacetamide DMAc. Raws li cov tub ntxhais - spinning hnyav rau acrylic fibers, polyurethane elastomers, thiab siab - lub zog aramid fibers, nws stabilizes cov qauv molecular thaum lub sij hawm tsim fiber ntau thiab txhim kho cov uniformity ntawm cov xov paj tiav. Tsis tas li ntawd, DMAc yog cov khoom siv tseem ceeb hauv kev tsim cov siab -lub zog polyimide zaj duab xis thiab cov txheej txheem tiv thaiv kev lag luam.
Pharmaceutical thiab Fine Chemical Synthesis
Hauv kev lag luam kws tshuaj, N,N-Dimethylacetamide DMAc yog qhov huv si, qis- cov tshuaj tiv thaiv impurity nruab nrab. Nws yog dav siv nyob rau hauv peptide synthesis, tshuaj tua kab mob, thiab ntau yam complex tshuaj intermediate tshua, zoo txhim kho cov tshuaj tiv thaiv hloov dua siab tshiab. Hauv kev tsim cov tshuaj tua kab, DMAc ua haujlwm ruaj khov pabcuam, txhim kho cov khoom lag luam ruaj khov thiab ua haujlwm tau zoo.
Cov Khoom Siv Tshwj Xeeb thiab Cov Txheej Txheem Hluav Taws Xob
Hauv petrochemical refining, DMAC cov kuab tshuaj yog siv los ua cov kuab tshuaj muaj txiaj ntsig zoo rau kev tshem tawm cov distillation, sib cais cov styrene Cheebtsam los ntawm C8 sib xyaw cov feem, yog li txhim kho kev siv cov khoom siv raw. Hauv kev lag luam hluav taws xob, DMAc yog siv rau kev ua kom huv si ntawm cov khoom siv semiconductor thiab kev npaj ntawm photoresist strippers.
