1. He mea hoʻoheheʻe maikaʻi loa ia, hoʻohana nui ʻia e like me ka extractant no ka hoʻomaʻemaʻe ʻana i nā meaʻala, ka hoʻomaʻemaʻe ʻana i ka aila, ka ʻike acetylene, syngas desulfurization, etc., a hoʻohana pū ʻia i ka hoʻomaʻemaʻe ʻoihana, etc.
2. ʻO N-methylpyrrolidone kahi mea hoʻoheheʻe hoʻoheheʻe maikaʻi loa. Hoʻohana nui ʻia ʻo ia ma ke ʻano he extractant i ke kaʻina o ka hoʻoheheʻe ʻana i nā mea ʻala, ka ʻike acetylene, ka hoʻokaʻawale butadiene a me ka synthesis gas desulfurization. He mea ia no hoi he pesticide, 'enekinia plastic, Solvents i ka hana o ka uhi, synthetic fibers, integrated kaapuni, etc., hiki ke hoʻohana 'ia e like me ka hanaʻoihana detergents, dispersants, dyes, lubricants a me ka antifreeze, etc. ʻO ka LD50 waha no nā ʻiole he 7ml/kg.
3. Hoʻohana nui ʻia i ka hoʻomaʻemaʻe ʻana i ka aila lubricating kiʻekiʻe, ka polymer synthesis, insulating material, pesticides, pigments a me nā mea hoʻomaʻemaʻe, etc.
4. Mea hoohehee. Hoʻohui ʻia.
5. Hoʻohana ʻia i ka ʻili ʻala, hoʻomaʻemaʻe i ka acetylene, olefin, a me diolefin; hoʻohana ʻia i loko o ka polymer solvent a me ka polymerization medium, e like me ka ʻenekinia plastics e like me polyamide, polyimide, polyphenylene sulfide, a me ka fiber aramid Hoʻohana ʻia e like me ka solvent a extractant. ʻO NMP he mea hoʻoheheʻe polar aprotic me ka haʻahaʻa haʻahaʻa, kahi paila kiʻekiʻe, solubility koʻikoʻi, koho ikaika a paʻa maikaʻi. Hoʻohana nui ʻia ia i ka unuhi ʻana i nā mea ʻala; hoʻomaʻemaʻe i ka acetylene, olefins a me diolefins. Hoʻohana ʻia ia no nā mea hoʻoheheʻe polymer a me ka media polymerization. E like me ka polyamide, polyimide, polyphenylene sulfide a me nā mea ʻenehana ʻenehana a me nā fiber aramid. Hoʻohana ʻia ia i nā mea insulating, pesticides, pigments a me nā mea holoi.
