N,N-Dimethylformamide DMF CAS 68-12-2 - siv
Thawj qhov kev siv ntawm dimethylformamide DMF yog cov kuab tshuaj uas tsis tshua muaj evaporation. DMF kuab tshuaj yog siv nyob rau hauv zus tau tej cov acrylic fibers thiab yas. Nws kuj yog siv los ua cov kuab tshuaj hauv peptide coupling rau kev siv tshuaj, hauv kev txhim kho thiab tsim cov tshuaj tua kab, thiab hauv kev tsim cov nplaum, hluavtaws tawv, fibers, films, thiab txheej txheej.
N,N-Dimethylformamide yog siv los ua cov tshuaj reagent.
DMF nkag mus rau feem ntau cov yas thiab ua rau lawv o. Nws yog li ntawd feem ntau tshwm sim raws li ib feem ntawm cov xim strippers.
Nws kuj yog siv rau hauv kev tsim cov kuab tshuaj dyes ua ib qho tseem ceeb raw khoom. Nws yog noj thaum lub sij hawm cov tshuaj tiv thaiv.
