N, n {- dimethylacetamide (DMAC) siv
1. Dimethylacetamide yog cov kuab tshuaj zoo sab qab zib thiab yog siv los ua cov khoom siv raw rau cov khoom siv hluavtaws thiab hluav taws xob organic.
2. Nws tseem siv nyob rau hauv cov khoom siv hauv nruab nrog cev yog cov kuab tshuaj, catalyst thiab xim remover.
3. DMAC feem ntau yog siv nyob rau hauv kev tsim cov hluavtaws ntau zog (acrylonitrile), polyurethane spinning thiab hluavtaws polyamide resins. Nws kuj tseem siv los ua cov kuab tshuaj rau cov distactive excillation thiab kev sib cais ntawm styrene los ntawm C8 feem. Nws yog dav siv nyob rau hauv cov yeeb yaj kiab polymer, cov tshuaj pleev, tshuaj, thiab lwm yam.
4. Tam sim no, nws yog siv nyob rau hauv synthesis ntawm cov tshuaj tua kab mob thiab tshuaj tua kab mob hauv cov tshuaj thiab kev ua liaj ua teb. Nws tseem muaj raws li kev catalyst ntawm kev phiv tshuaj, ib qho kev daws teeb meem electrolytic, pleev xim rau cov xim pleev xim thiab ntau yam crystalline cov kuab tshuaj ntxiv thiab cov nyom.
