DMF (N, N-Dimethylformamide) thiab DMAC (N, N-Dimethylacetamide) yog cov organic solvents uas tau siv dav hauv kev lag luam tshuaj, tshuaj, hluav taws xob thiab fiber ntau. Lawv lub ntsiab sib txawv yog raws li nram no:
Dimethylacetamide (CAS 127-19-5) yog dab tsi?
| Feature | DMAc (DMA) | DMF |
|---|---|---|
| Lub npe tag nrho | N,N{0}}Dimethylacetamide | N,N{0}}Dimethylformamide |
| CAS nr | 127-19-5 | 68-12-2 |
| Tshuaj pab pawg | Amide (Acetamide) | Amide (formamide) |
| Boiling point | ~ 165-166 degree | ~ 153 degree |
| tsw | Me me, tsawg pungent | Strong fishy/ammonia-zoo li |
| Solvent zog | Ntxiv me ntsis | Muaj zog hnyav zog |
| Kev ruaj ntseg | Ntau thermally ruaj khov | Me ntsis ruaj khov thaum kub kub |
| Kev siv | Fibers, PU, txheej, membranes | Resins, kws tshuaj, acrylics |
Chemical structure txawv:
N,N-Dimethylacetamide DMAc (DMA) muaj ib pawg acetamide (CH₃CON(CH₃)₂).
N,N-Dimethylformamide DMF muaj ib pawg formamide (HCON(CH₃)₂).
Muaj kev thov sib txawv
N, N-Dimethylformamide DMF hnyav: Siv nyob rau hauv ntub spinning ntawm polyacrylonitrile fibers, raws li ib tug hnyav rau acrylic yas, thiab nyob rau hauv peptide coupling cov tshuaj tiv thaiv nyob rau hauv kev tsim tshuaj.
N,N-Dimethylacetamide DMAc hnyav: Cov kuab tshuaj zoo dua rau kev ua kom cov polymers, xws li polyurethane. Vim nws txoj kev ruaj ntseg, nws yog feem ntau siv rau hauv kev tsim cov hluavtaws fibers thiab cov yeeb yaj kiab.
