O le N-methylpyrrolidone o loʻo taʻua o le NMP, molecular formula: C5H9NO, Igilisi: 1-Methyl-2-pyrrolidinone, foliga e leai se lanu i le moli samasama manino vai, sina manogi o le amonia, miscible ma le vai i soʻo se vaega, soluble i le eter, acetone. Ma eseese solvents organic e pei o esters, halogenated hydrocarbons, hydrocarbons aromatic, ma isi, e atoatoa chemically fefiloi ma toetoe lava solvents uma, faatasi ai ma le vevela o le 204°C ma le moli o le 91°C. E malosi lona hygroscopicity ma mautu mea kemikolo. E le fa'aleagaina le uamea kaponi ma le alumini, ma e le afaina i le 'apamemea. E pala teisi. O loʻo i ai le lelei o le maualalo o le viscosity, vailaʻau lelei ma le mafanafana, maualuga polarity, maualalo le vaʻaia, ma le le faʻatapulaʻaina miscibility i le vai ma le tele o solvents organic. O lenei oloa o se micro-drug, ma le fa'ataga fa'agata fa'atonuga i le ea o le 100PPM.

O mea fa'aletino ma vaila'au N-methylpyrrolidone ose vai e leai se lanu e o'o ile lanu samasama manino ma sina manogi ammonia. E fa'afefiloi ma le vai i so'o se vaega ma soluble i solu fa'alela'au eseese e pei ole eter, acetone ma esters, hydrocarbons halogenated, Chemicalbook aromatics, ma isi, toetoe lava Faafefiloi mae'ae'a ma solvents uma. E fai si mautu i le vaifofo le faaituau; e faasolosolo malie i le hydrolyzes hydrochloric acid concentrated e maua ai le 4-methylaminobutyric acid.

Fa'amoemoega N-methylpyrrolidone (NMP) o se vaifofo polar aprotic. E maualalo le oona, maualuga le vevela ma sili ona solubility. Tulaga lelei o le filifilia malosi ma le mautu lelei. Fa'aaogaina lautele i le su'eina o le hydrocarbon manogi, fa'amamāina o le acetylene, olefins ma dienes, solvent mo polyvinylidene fluoride, electrode mea fesoasoani mo ma'a lithium-ion, syngas desulfurization, lubricating suau'u fa'amamaina, lubricating suau'u anetiisaisa, Chemicalbook olefin su'esu'ega sooupu, Solvents mo le polymerization. palasitika inisinia insoluble, herbicides faatoaga, mea insulation, tuufaatasia matagaluega gaosiga, faamamaina o meafaifaaili saʻo ma laupapa matagaluega i le alamanuia semiconductor, PVC kasa toe faaleleia, faamamaina sui, vali faaopoopo, dispersants, ma isi E faaaogaina foi e avea o se solvent mo polymers ma se ala mo tali polymerization, e pei o palasitika inisinia ma alava aramid. E le gata i lea, e mafai foi ona faʻaaogaina i vailaau faʻasaina, vailaʻau ma vailaʻau, ma isi.
