Fa'asologa o vaila'au fa'avae–N-methylpyrrolidone (NMP)

Igoa vailaʻau: N-methyl-2-pyrrolidone; 1-methyl-2-pyrrolidone; nitrogen-methylpyrrolidone.
CAS NO.:872-50-4
Fua fa'atatau molekiula: C5H9NO

Igoa Peretania: N-methyl-2-pyrrolidone
Meatotino: O le N-methylpyrrolidone (NMP pe a faapuupuu) o se vailaʻau heterocyclic nitrogen ma se fua faʻatatau molecular o le C5H9NO ma se tulaga pupuna o le 204°C. O se vai e iai sina manogi ammonia. E mafai ona fefiloi ma le vai i soʻo se fua faʻatatau ma e fetaui ma toetoe lava o vailaʻau faʻamama uma (ethanol, ethanol, Acetaldehyde, ketones, aromatic hydrocarbons, ma isi) e palu atoatoa.

O le NMP o se vaila'au fa'a-aprotic polar ma le maualuga o le pupuna, malosi le polarity, maualalo le viscosity, malosi le solubility, e le fa'aleagaina, maualalo le oona, malosi le pala o le tino, maualalo le volatility, lelei tele le mautu o vaila'au ma le mautu o le vevela.

Faiga o le gaosiga: Ua leva ona fa'atekonolosiaina le NMP ma ua matua le tekinolosi. O lona faiga o le gaosiga e aofia ai le fa'amamāina o le 1,4-butanediol (BDO) e maua ai le γ-butyrolactone (GBL), ona fa'amamāina lea o le γ-butyrolactone ma le monomethylamine. O le tali atu e maua ai ni oloa, ona fa'amamāina lea ma fa'amamāina i totonu o le oloa ua mae'a o le NMP.

Vaega e fa'aoga ai

O le N-Methylpyrrolidone o se vailaʻau faʻamamā lelei tele e faʻaaogaina i vailaʻau gaosi petrochemicals, vailaʻau faʻasaina, vailaʻau, mea eletise ma isi matāʻupu. E mafai ona faʻaaogaina e pei o le acetylene concentration, syngas desulfurization, lubricating oil refining, lubricating oil antifreeze, olefin extraction agent, solvent i le polymerization o insoluble engineering plastics, faʻatoʻaga herbicides, insulation materials, integrated circuit production, PVC exhaust gas recovery, cleaning agent, dye auxiliaries, dispersants, ma isi mea.
