N-methylpyrrolidone, NMP; 1-methyl-2pyrrolidone; N-methyl-2-pyrrolidone. ʻO ka wai ʻaila ʻālohilohi kala ʻole me ka ʻala amine liʻiliʻi. Hiki ke hui pū me ka wai, nā waiʻona, nā etera, nā esters, nā ketones, nā mea halogenated hydrocarbons, nā meaʻala a me ka aila castor. Haʻahaʻa volatility, maikaʻi wela a me ka paʻa kemika, a hiki ke evaporate me ka wai mahu. He hygroscopic. Pilikino i ka malamalama.
Hoʻohana nui ʻia ka N-methylpyrrolidone i nā ʻoihana e like me nā pā lithium, lāʻau lapaʻau, pesticides, pigments, mea hoʻomaʻemaʻe, a me nā mea insulating.
ʻO ka wai ʻaila ʻālohilohi kala ʻole me ka ʻala amine liʻiliʻi. Hiki ke hoʻopili ʻia me ka wai, ka waiʻona, ka etera, ka ester, ketone, ka halogenated hydrocarbon a me ka aromatic hydrocarbon.
1) He mea hoʻoheheʻe maikaʻi loa ia, hoʻohana nui ʻia ma ke ʻano he extractant no ka hoʻomaʻemaʻe ʻana i nā meaʻala, hoʻomaʻemaʻe ʻaila hinu, acetylene concentration, syngas desulfurization, etc., a hoʻohana pū ʻia i ka hoʻomaʻemaʻe ʻoihana, etc.
2) N-methylpyrrolidone he mea hoʻoheheʻe maikaʻi loa, hoʻohana nui ʻia e like me ka extractant i ke kaʻina hana o ka hoʻoneʻe ʻana i nā mea ʻala, ka ʻike acetylene, ka wehe ʻana o ka butadiene a me ka synthesis gas desulfurization. I ka manawa like, ʻo Chemicalbook kekahi mea pesticide a me ka plastic engineering. ʻO nā mea hoʻoheheʻe i ka hana ʻana o, coatings, synthetic fibers, integrated circuit, etc., a hiki ke hoʻohana ʻia e like me nā detergents ʻoihana, dispersants, dyes, lubricants, antifreeze, etc.
3) Hoʻohana nui ʻia i ka hoʻomaʻemaʻe ʻana i ka aila lubricating kiʻekiʻe, polymer synthesis, insulating material, pesticides, pigments a me nā mea hoʻomaʻemaʻe, etc.
4) Hoʻoheheʻe. Hoʻohui ʻia.
5) Hoʻohana ʻia i ka ʻili ʻala, hoʻomaʻemaʻe i ka acetylene, olefin, a me ka diolefin; hoʻohana ʻia i ka polymer solvent a me ka polymerization medium, e like me nā plastics engineering e like me polyamide, polyimide, polyphenylene sulfide, a me ka fiber aramid.
6) Hoʻohana ʻia e like me ka solvent a me ka extractant.
