    Kugwiritsa ntchito

    1. Ndiwosungunulira wabwino kwambiri, womwe umagwiritsidwa ntchito kwambiri ngati mankhwala opangira ma aromatics, mafuta oyeretsera mafuta, acetylene concentration, syngas desulfurization, etc., komanso amagwiritsidwa ntchito poyeretsa mafakitale, etc.

    2. N-methylpyrrolidone ndi yabwino kwambiri m'zigawo zosungunulira. Amagwiritsidwa ntchito kwambiri ngati chotsitsa potulutsa zonunkhira, ndende ya acetylene, kulekana kwa butadiene ndi synthesis gas desulfurization. Ndi mankhwala ophera tizilombo, pulasitiki yaumisiri, zosungunulira popanga zokutira, ulusi wopangira, mabwalo ophatikizika, etc., zitha kugwiritsidwanso ntchito ngati zotsukira mafakitale, dispersants, utoto, lubricants ndi antifreeze, etc. LD50 yapakamwa ya makoswe ndi 7ml/kg.

    3. Amagwiritsidwa ntchito kwambiri poyenga mafuta opaka mafuta apamwamba kwambiri, kaphatikizidwe ka polima, zida zotetezera, mankhwala ophera tizilombo, ma pigment ndi oyeretsa, ndi zina zambiri.

    4. Zosungunulira. Organic Synthesis.

    5. Amagwiritsidwa ntchito pochotsa zonunkhira, kuyeretsa acetylene, olefin, ndi diolefin; ntchito polima zosungunulira ndi polymerization sing'anga, monga mapulasitiki engineering monga polyamide, polyimide, polyphenylene sulfide, ndi aramid CHIKWANGWANI Ntchito monga zosungunulira ndi extractant. NMP ndi polar aprotic zosungunulira zomwe zimakhala ndi kawopsedwe kochepa, malo otentha kwambiri, kusungunuka kwapadera, kusankha mwamphamvu komanso kukhazikika kwabwino. Amagwiritsidwa ntchito kwambiri pochotsa aromatics; kuyeretsa acetylene, olefins ndi diolefins. Amagwiritsidwanso ntchito polima solvents ndi polymerization media. Monga polyamide, polyimide, polyphenylene sulfide ndi mapulasitiki ena aumisiri ndi ulusi wa aramid. Amagwiritsidwanso ntchito mu insulating zipangizo, mankhwala ophera tizilombo, inki ndi zotsukira.
