O le N-methylpyrrolidone e ta'ua o le NMP, o le fua fa'atatau molecular: C5H9NO, Igilisi: 1-Methyl-2-pyrrolidinone, o lona foliga e leai se lanu i se vai manino samasama vaivai, e fai si manogi o le ammonia, e mafai ona palu fa'atasi ma le vai i so'o se vaega, e mafai ona palu fa'atasi i le ether, acetone ma le tele o solvents organic e pei o esters, halogenated hydrocarbons, aromatic hydrocarbons, ma isi, e palu fa'atasi ma toetoe lava o solvents uma, ma le pupuna o le 204°C ma le flash point o le 91°C. E malosi lona hygroscopicity ma e mautu fo'i ona meatotino fa'akemikolo. E le fa'aleagaina le u'amea kaponi ma le alumini, ma e le fa'aleagaina fo'i le kopa. E fai si fa'aleagaina. E iai ona lelei o le maualalo o le viscosity, lelei le mautu o vaila'au ma le vevela, maualuga le polarity, maualalo le volatility, ma e le fa'atapula'aina le fefiloi ma le vai ma le tele o solvents organic. O lenei oloa o se micro-drug, ma o le tapula'a fa'atagaina i le ea o le 100PPM.

Uiga faaletino ma vailaʻau O le N-methylpyrrolidone o se vai e leai se lanu pe samasama vaivai e manino ma sina manogi ammonia. E mafai ona palu faatasi ma le vai i soʻo se fua faatatau ma e mafai ona solo i le tele o solvents organic e pei o le ether, acetone ma esters, halogenated hydrocarbons, Chemicalbook aromatics, ma isi, e toetoe lava a palu faatasi ma solvents uma. E fai si mautu i le vai e leai se lagona; e faasolosolo malie ona hydrolyze i le hydrochloric acid faʻaputu e faʻatupu ai le 4-methylaminobutyric acid.

Fa'amoemoega O le N-methylpyrrolidone (NMP) o se vaila'au fa'a-aprotic polar. E maualalo lona o'ona, maualuga le tulaga pupuna ma lelei tele le solubility. O lelei o le malosi o le selectivity ma le mautu lelei. E fa'aaogaina lautele i le fa'amamāina o le aromatic hydrocarbon, fa'amamāina o le acetylene, olefins ma dienes, vaila'au fa'a-polyvinylidene fluoride, mea fesoasoani eletise mo maa lithium-ion, syngas desulfurization, fa'amamāina o le suau'u fa'asusu, vaila'au fa'asusu o le suau'u fa'asusu, vaila'au fa'amamā olefin a le Chemicalbook, Vaila'au fa'amamā mo le polymerization o palasitika fa'ainisinia e le mafai ona solo, vaila'au fa'ato'aga, mea fa'avevela, gaosiga o matagaluega tu'ufa'atasi, fa'amamāina o meafaigaluega sa'o ma laupapa matagaluega i le alamanuia semiconductor, toe fa'aleleia o kasa oona PVC, vaila'au fa'amamā, mea fa'aopoopo vali, fa'asalalau, ma isi. E fa'aaogaina fo'i o se vaila'au fa'asusu mo polymers ma se auala mo tali atu o le polymerization, e pei o palasitika fa'ainisinia ma alava aramid. E le gata i lea, e mafai fo'i ona fa'aaogaina i vaila'au fa'asaina, vaila'au ma vaila'au fufulu, ma isi.
