I-N-methylpyrrolidone ibizwa nge-NMP, ifomula yamangqamuzana: C5H9NO, isiNgisi: 1-Methyl-2-pyrrolidinone, ukubukeka akunambala uketshezi olukhanyayo olukhanyayo oluphuzi, iphunga elincane le-ammonia, kuxubana namanzi kunoma iyiphi ingxenye, kuncibilika ku-ether, i-acetone. Futhi izinyibilikisi ezihlukahlukene eziphilayo ezifana nama-esters, ama-halogenated hydrocarbons, ama-hydrocarbon anephunga elimnandi, njll., ahlanganiswe ngokuphelele ngamakhemikhali nawo wonke ama-solvents, anephuzu elibilayo elingu-204°C kanye nephuzu elikhanyayo elingu-91°C. Ine-hygroscopicity eqinile kanye nezakhiwo zamakhemikhali ezizinzile. Ayigqwali i-carbon steel ne-aluminium, futhi ayigqwali ethusi. Iyagqwala kancane. Inezinzuzo ze-viscosity ephansi, ukuzinza okuhle kwamakhemikhali kanye nokushisa, i-polarity ephezulu, ukuguquguquka okuphansi, nokungahambisani okungenamkhawulo namanzi kanye nezinyibilikisi eziningi eziphilayo. Lo mkhiqizo uyisidakamizwa esincane, futhi umkhawulo ovumelekile wokugxila emoyeni ngu-100PPM.

Izakhiwo zomzimba kanye namakhemikhali I-N-methylpyrrolidone iwuketshezi olukhanyayo olukhanyayo olukhanyayo oluphuzi olunephunga elincane le-ammonia. Ixubene namanzi kunoma iyiphi ingxenye futhi inyibilika kuzincibilikisi zemvelo ezihlukahlukene njenge-ether, i-acetone nama-ester, ama-halogenated hydrocarbon, i-Chemicalbook aromatics, njll., cishe Hlanganisa kahle nazo zonke izincibilikisi. Izinzile kusixazululo esingathathi hlangothi; kancane kancane i-hydrolyzes ku-hydrochloric acid egxilile ukuze ikhiqize i-4-methylaminobutyric acid.

Ukubukeka Uketshezi olungenambala olubonisa ngale (ngaphezu kuka-25℃)
Ubumsulwa% ≥99.5
Umswakama% ≤0.1
I-Chroma HaZen ≤25
Inkomba ye-Refractive N20D 1.468-1.471
Ukuminyana 1.032-1.035

Inhloso i-N-methylpyrrolidone (NMP) iyincibilikisi ye-polar aprotic. Inobuthi obuphansi, indawo yokubilisa ephezulu kanye nokuncibilika okuhle kakhulu. Izinzuzo zokukhetha okuqinile nokuzinza okuhle. Isetshenziswa kakhulu ekukhishweni kwe-hydrocarbon enamakha, ukuhlanzwa kwe-acetylene, ama-olefin nama-dienes, i-solvent ye-polyvinylidene fluoride, izinto ezisizayo ze-electrode zamabhethri e-lithium-ion, i-syngas desulfurization, ukucwenga uwoyela wokuthambisa, ukuthambisa uwoyela wokuthambisa, i-Chemicalbook olefin extraction agent ye-polymervent amapulasitiki obunjiniyela angenakuncibilika, ama-herbicide ezolimo, izinto zokufakelwa, ukukhiqizwa kwesekethe edidiyelwe, ukuhlanzwa kwezinsimbi ezinembayo namabhodi wesifunda embonini ye-semiconductor, i-PVC exhaust gas recovery, ama-ejenti okuhlanza, izithasiselo zikadayi, ama-disperants, njll. Ibuye isetshenziswe njenge-solvent yama-polymers. kanye nendlela yokusabela kwe-polymerization, njengamapulasitiki wobunjiniyela nama-aramid fibers. Ngaphezu kwalokho, ingasetshenziswa nasezintweni zokubulala izinambuzane, imithi kanye nezihlanzi, njll.
