CAS 68-12-2 Dimethylformamide(lub npe DMF), tseem hu ua N, N-dimethylformamide, yog dimethyl hloov pauv ntawm formamide, thiab ob pawg methyl nyob rau ntawm N (nitrogen) atoms, yog li nws yog lub npe. DMF yog cov kua xim tsis muaj xim thiab pob tshab nrog lub siab kub kub, qhov chaw khov qis, cov tshuaj zoo thiab thermal stability, thiab yog miscible nrog dej thiab feem ntau cov kuab tshuaj organic.
Raws li ib qho tseem ceeb ntawm cov khoom siv raw khoom thiab cov kuab tshuaj zoo heev, DMF (dimethylformamide) yog dav siv hauv polyurethane, acrylic, khoom noj khoom haus additives, tshuaj, tshuaj tua kab, dyes, electronics thiab lwm yam lag luam.

N,N-Dimethylformamide DMF Solvent cov ntawv thov tseem ceeb
1. Cov kuab tshuaj: Cov kuab tshuaj polar muaj zog siv ntau yam tshuaj lom neeg thiab cov txheej txheem kev lag luam.
N,N-Dimethylformamide DMF yog lub zog polar aprotic hnyav nrog lub siab dielectric tas li thiab muaj peev xwm daws tau qhov tshwj xeeb, ua kom nws yaj ntau yam ntawm cov organic thiab inorganic compounds.
2. Pharmaceuticals: Nws yog siv los ua ib qho hnyav rau kev tsim tshuaj thiab hauv kev tsim cov khoom xyaw tshuaj nquag.
CAS 68-12-2 DMF Dimethylformamide yog qhov nruab nrab tseem ceeb rau kev sib xyaw thiab crystallising APIs hauv cov tshuaj. Nws cov purity siab thiab ruaj khov nyob rau hauv cov kev mob nruj ua kom muaj kev ua tau zoo nyob rau hauv ntau cov kauj ruam syntheses thiab pab txoj kev loj hlob ntawm kev tswj-tso tshuaj formulations.
3. Polymer kev lag luam: Nws yog siv rau hauv kev tsim cov polymers xws li acrylic fibers.
DMF chemical yog thawj qhov kev lag luam hnyav siv los tsim cov acrylic fibers, vim nws txawv txav polyacrylonitrile los ua spin dope rau ntub - cov txheej txheem spinning. DMF kuj tseem yog qhov tseem ceeb rau kev sib txuas thiab ua cov polyurethanes, polyimides thiab lwm yam siab -cov khoom siv polymers.
4. Electronics: Nws yog siv rau hauv kev tsim khoom ntawm semiconductors thiab ntxuav cov khoom siv hluav taws xob.
Ultra-DMF dawb huv (cas 68 12 2) yog siv rau hauv photoresist stripping, PCB tu thiab ua hnyav rau polyimide txheej hauv cov txheej txheem hloov pauv. Nws lub peev xwm los tshem tawm cov organic residues yam tsis tau tawm hauv cov kab yog qhov tseem ceeb rau kev tsim cov khoom siv semiconductor thiab ua kom ntseeg tau ntawm cov khoom.
