N,N-Dimethylformamide tseem hu ua DMF, yog xim tsis muaj xim rau daj pob tshab kua nrog kub kub taw tes nrog faint, tshwj xeeb amine - zoo li tsw. Nws yog miscible nrog dej. DMF kua yog hydrophilic thiab polar aprotic hnyav, uas yuav ua rau kom cov tshuaj tiv thaiv SN2. Muaj zog alkali los yog acide (tshwj xeeb tshaj yog nyob rau hauv high kub), DEHA hydrolyses rau formic acid thiab dimethylallylamine.

Kev siv Dimethylformamide (DMF)
N,N-Dimethylformamide DMF feem ntau yog siv los ua cov kuab tshuaj hauv kev tsim cov acrylic fibers, yas, thiab tshuaj. Nws kuj tseem ua haujlwm nyob rau hauv kev tsim tshuaj tua kab, nplaum, hluavtaws tawv, thiab txheej txheej. Hauv cov chaw soj nstuam, DMF tshuaj siv los ua cov tshuaj reagent hauv cov organic synthesis thiab ua cov kuab tshuaj rau NMR spectroscopy.
DMF CAS 68-12-2 toxic
N,N-Dimethylformamide tuaj yeem muaj tshuaj lom yog tias nqus tau, noj, lossis nqus los ntawm daim tawv nqaij ntau. Nws raug cais raws li kev phom sij thiab yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb, suav nrog PPE thiab qhov cua txaus.
Kev nyab xeeb thiab tuav
Txawm hais tias nws siv dav hauv kev lag luam, DMF (cas 68 12 2) chemical yog cais raws li cov tshuaj phem thiab yuav tsum tsuas yog siv rau hauv ib puag ncig tswj. Dimethylformamide tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv los ntawm kev nqus pa lossis kev sib chwv ntawm daim tawv nqaij, yog li kev tswj xyuas kom zoo, PPE, thiab qhov cua yog qhov tseem ceeb.
