I-N-methylpyrrolidone ibizwa ngokuthi i-NMP, ifomula yama-molecule: C5H9NO, isiNgisi: 1-Methyl-2-pyrrolidinone, ukubukeka kwayo akunambala kuya kokukhanya okuphuzi okukhanyayo okukhanyayo, iphunga elincane le-ammonia, ixubene namanzi nganoma iyiphi indlela, incibilika ku-ether, i-acetone kanye nezinyibilikisi ezahlukahlukene eziphilayo ezifana nama-esters, ama-hydrocarbons e-halogenated, ama-hydrocarbons aromatic, njll., ixubene ngokuphelele ngamakhemikhali cishe nazo zonke izinyibilikisi, ngephuzu lokubila elingu-204°C kanye nephuzu lokushelela elingu-91°C. Ine-hygroscopicity eqinile kanye nezakhiwo zamakhemikhali ezizinzile. Ayigqwali insimbi yekhabhoni kanye ne-aluminium, futhi ayigqwali ithusi. Igqwala kancane. Inezinzuzo ze-viscosity ephansi, ukuzinza okuhle kwamakhemikhali nokushisa, i-polarity ephezulu, ukuguquguquka okuphansi, kanye nokuxubana okungenamkhawulo namanzi kanye nezinyibilikisi eziningi eziphilayo. Lo mkhiqizo umuthi omncane, futhi ukuhlushwa okulinganiselwe okuvunyelwe emoyeni kungu-100PPM.

Izakhiwo zomzimba nezamakhemikhali I-N-methylpyrrolidone iwuketshezi olukhanyayo olungenambala noma olukhanyayo oluphuzi olunephunga elincane le-ammonia. Ixubene namanzi nganoma iyiphi indlela futhi iyancibilika ezinyibilikisini ezahlukahlukene zezinto eziphilayo ezifana ne-ether, i-acetone nama-esters, ama-hydrocarbon ane-halogenated, ama-Chemicalbook aromatics, njll., Cishe ixubene kahle nazo zonke izinyibilikisi. Izinzile kakhulu esixazululweni esingathathi hlangothi; kancane kancane i-hydrolyzes ku-hydrochloric acid egxilile ukuze ikhiqize i-4-methylaminobutyric acid.

Ukubukeka koketshezi olungabonakali olungenambala (ngaphezu kwama-25℃)
Ubumsulwa% ≥99.5
Umswakama% ≤0.1
I-Chroma HaZen ≤25
Inkomba yokubuka kabusha i-N20D 1.468-1.471

I-N-methylpyrrolidone (NMP) enenjongo iyi-solvent ye-polar aprotic. Inobuthi obuphansi, iphuzu lokubila eliphezulu kanye nokuncibilika okuhle kakhulu. Izinzuzo zokukhetha okuqinile kanye nokuqina okuhle. Isetshenziswa kabanzi ekukhishweni kwe-aromatic hydrocarbon, ukuhlanzwa kwe-acetylene, ama-olefin nama-dienes, i-solvent ye-polyvinylidene fluoride, izinto ezisizayo ze-electrode zamabhethri e-lithium-ion, i-syngas desulfurization, i-lubricating oil refine, i-lubricating oil antifreeze, i-Chemicalbook olefin extraction agent, i-solvents ye-polymerization yamapulasitiki obunjiniyela angancibiliki, ama-herbicides ezolimo, izinto zokushisa, ukukhiqizwa kwesekethe ehlanganisiwe, ukuhlanzwa kwezinsimbi zokunemba namabhodi wesekethe embonini ye-semiconductor, ukubuyiswa kwegesi yokukhipha i-PVC, ama-cleaner agents, izithasiselo zodayi, ama-dispersants, njll. Iphinde isetshenziswe njenge-solvent yama-polymers kanye nendawo yokusabela kwe-polymerization, njengepulasitiki yobunjiniyela kanye nemicu ye-aramid. Ngaphezu kwalokho, ingasetshenziswa nasezibulala-zinambuzane, emithini nasezinhlwini zokuhlanza, njll.
