N-methylpyrrolidone i kapa ʻia ʻo NMP, molecular formula: C5H9NO, English: 1-Methyl-2-pyrrolidinone, ʻaʻole waihoʻoluʻu ka helehelena i ka wai aniani melemele māmā, ʻala iki o ka amonia, hiki ke hoʻoheheʻe ʻia me ka wai i kēlā me kēia ʻāpana, hiki ke hoʻoheheʻe ʻia i ka etera, acetone. A ʻo nā mea hoʻoheheʻe ʻokoʻa like ʻole e like me nā esters, halogenated hydrocarbons, aromatic hydrocarbons, a me nā mea ʻē aʻe, ua hui pū ʻia me nā mea hoʻoheheʻe a pau loa, me kahi paila o 204 ° C a me kahi kiko uila o 91 ° C. Loaʻa iā ia ka hygroscopicity ikaika a me nā waiwai kemika paʻa. ʻAʻole ia e hoʻopōʻino i ke kila kalapona a me ka aluminika, a ʻaʻole ia e ʻino i ke keleawe. ʻAiʻino iki. Loaʻa iā ia nā pōmaikaʻi o ka viscosity haʻahaʻa, kemika maikaʻi a me ke kūpaʻa wela, ka polarity kiʻekiʻe, ka haʻahaʻa haʻahaʻa, a me ka miscibility palena ʻole me ka wai a me nā mea hoʻonā he nui. ʻO kēia huahana he micro-drug, a ʻo ka palena palena ʻae ʻia i ka lewa he 100PPM.

Nā waiwai kino a me ke kemika N-methylpyrrolidone he wai ʻaʻohe waihoʻoluʻu a ʻulaʻula melemele me ka ʻala iki o ka ammonia. Hiki ke hoʻoheheʻe ʻia me ka wai i kekahi ʻāpana a hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me ka etera, acetone a me nā esters, halogenated hydrocarbons, Chemicalbook aromatics, a me nā mea ʻē aʻe. He paʻa i ka hoʻonā kuʻuna; hoʻokahe mālie ia i loko o ka waika hydrochloric concentrated e hoʻohua i ka waikawa 4-methylaminobutyric.
