1. Nws yog cov kuab tshuaj zoo heev, dav siv los ua cov extractant rau aromatics extraction, lubricating roj refining, acetylene concentration, syngas desulfurization, thiab lwm yam, thiab kuj siv nyob rau hauv industrial tu, thiab lwm yam.
2. N-methylpyrrolidone yog ib qho zoo heev extraction hnyav. Nws yog dav siv raws li ib tug extractant nyob rau hauv cov txheej txheem ntawm aromatic extraction, acetylene concentration, butadiene sib cais thiab synthesis roj desulfurization. Nws kuj yog tshuaj tua kab, engineering yas, Cov kuab tshuaj hauv kev tsim cov coatings, hluavtaws fibers, integrated circuits, thiab lwm yam, kuj tseem siv tau los ua cov tshuaj detergents, dispersants, dyes, lubricants thiab antifreeze, thiab lwm yam. Cov khoom muaj toxicity tsawg, thiab Qhov ncauj LD50 rau nas yog 7ml / kg.
3. Dav siv nyob rau hauv qib high-qib lubricating roj refining, polymer synthesis, insulating cov ntaub ntawv, tshuaj tua kab, pigments thiab tu neeg ua hauj lwm, thiab lwm yam.
4. Cov kuab tshuaj. Organic Synthesis.
5. Siv nyob rau hauv aromatic extraction, purification ntawm acetylene, olefin, thiab diolefin; siv nyob rau hauv polymer hnyav thiab polymerization nruab nrab, xws li engineering plastics xws li polyamide, polyimide, polyphenylene sulfide, thiab aramid fiber siv los ua hnyav thiab extractant. NMP yog ib tug polar aprotic hnyav uas tsis muaj toxicity, siab kub taw tes, zoo solubility, muaj zog xaiv thiab zoo stability. Nws yog dav siv nyob rau hauv extraction ntawm aromatics; purification ntawm acetylene, olefins thiab diolefins. Nws kuj yog siv rau cov kuab tshuaj polymer thiab polymerization media. Xws li polyamide, polyimide, polyphenylene sulfide thiab lwm yam engineering yas thiab aramid fibers. Nws kuj yog siv rau hauv cov ntaub ntawv insulating, tshuaj tua kab, pigments thiab detergents.
