N, N -Kev siv Dimethylformamide
- Solvent: Siv rau polyurethane, polyacrylonitrile, polyvinyl chloride (PVC), vinyl resin, thiab acetylene. Nws tseem muaj txiaj ntsig zoo hauv kev ua kom cov pigments uas tsis tshua muaj solubility thiab nyob rau hauv ntub spinning ntawm hluavtaws fibers xws li polyacrylonitrile.
- Extraction & Rov qab: Siv rau hauv extraction ntawm aromatics, rov qab ntawm butadiene thiab isoprene los ntawm C₄-C₅ fractions, thiab kev sib cais ntawm isophthalic acid thiab terephthalic acid.
- Catalyst & Reaction Medium: Ua raws li cov catalyst hauv hydrogenation, dehydrogenation, lub cev qhuav dej, thiab dehalogenation cov tshuaj tiv thaiv, txo cov tshuaj tiv thaiv kub thiab txhim kho cov khoom purity.
- Organic Synthesis: Ua haujlwm hnyav thiab nruab nrab rau cov tshuaj synthesis (xws li sulfadiazine, doxycycline, cortisone, vitamin B₆, tranexamic acid) thiab tshuaj tua kab (xws li chlordimeform).
- Kev siv tshuaj ntsuam xyuas: Ua haujlwm raws li kev tshuaj ntsuam reagent, theem nyob ruaj khov hauv cov pa roj chromatography, thiab reagent rau tsis yog -aqueous titration.
- Petrochemical & Photographic Fields: Siv los ua cov pa roj absorbent hauv cov txheej txheem petrochemical thiab hauv cov qauv tshuaj yees duab.
