I-N-methylpyrrolidone ibizwa ngokuba yi-NMP, ifomula yemolekyuli: C5H9NO, isiNgesi: 1-Methyl-2-pyrrolidinone, imbonakalo ayinambala ukuya kulwelo olukhanyayo olutyheli olucacileyo, ivumba elincinane le-ammonia, ixutywe namanzi nakweyiphi na imilinganiselo, inyibilika kwi-ether, i-acetone. Kwaye ezahlukeneyo izinyibilikisi eziphilayo ezifana esters, hydrocarbons halogenated, hydrocarbons aromatics, njl., ixutywe ngokwekhemikhali ngokupheleleyo phantse zonke izinyibilikisi, kunye neqondo lokubilisa lika-204 ° C kunye ne-flash point ye-91 ° C. Ine-hygroscopicity enamandla kunye neepropati ezizinzileyo zeekhemikhali. Ayina corrode carbon steel kunye ne-aluminium, kwaye ayinayo i-corrosion kwi-copper. Irhabaxa kancinane. Ineenzuzo ze-viscosity ephantsi, ikhemikhali elungileyo kunye nokuzinza kwe-thermal, i-polarity ephezulu, i-volatility ephantsi, kunye ne-miscibility engenamkhawulo ngamanzi kunye ne-solvents ezininzi zezinto eziphilayo. Le mveliso i-micro-drug, kwaye umyinge wokugxininiswa ovumelekileyo emoyeni yi-100PPM.

Iimpawu zomzimba kunye neekhemikhali i-N-methylpyrrolidone lulwelo olungenambala ukuya kumthubi olucacileyo olunevumba elincinane le-ammonia. Ixubene namanzi nakweyiphi na imilinganiselo kwaye inyibilika kwiintlobo ezahlukeneyo ze-solvents eziphilayo ezifana ne-ether, i-acetone kunye ne-esters, i-halogenated hydrocarbons, i-Chemicalbook aromatics, njl., Phantse Ukuxuba ngokucokisekileyo nazo zonke izinyibilikisi. Izinzile kwisisombululo esingathathi hlangothi; ngokuthe ngcembe i-hydrolyzes kwi-concentrated hydrochloric acid ukuvelisa i-4-methylaminobutyric acid.

Injongo ye-N-methylpyrrolidone (NMP) sisinyibilikisi sepolar aprotic. Inobuthi obuphantsi, indawo yokubilisa ephezulu kunye nokunyibilika okugqwesileyo. Izibonelelo zokukhetha okunamandla kunye nokuzinza okulungileyo. Isetyenziswa kakhulu kwi-extraction ye-hydrocarbon enevumba elimnandi, ukucocwa kwe-acetylene, i-olefins kunye ne-dienes, i-solvent ye-polyvinylidene fluoride, izixhobo ze-electrode ezincedisayo kwiibhetri ze-lithium-ion, i-syngas desulfurization, ukucocwa kwe-oyile yokuthambisa, ukuthambisa i-oyile yokuthambisa i-oyile, i-Chemicalbook olefin extraction agent ye-Solvent iiplastiki zobunjineli ezinganyibilikiyo, i-herbicides yezolimo, izinto zokugquma, imveliso yesekethe edibeneyo, ukucocwa kwezixhobo ezichanekileyo kunye neebhodi zesekethe kushishino lwe-semiconductor, i-PVC yokukhupha igesi yokubuyisela, i-agent yokucoca, izongezo zedayi, i-dipersants, njl. kunye nesixhobo sokusabela kwipolymerization, njengeeplastiki zobunjineli kunye neefiber ze-aramid. Ukongeza, inokusetyenziswa kwakhona kwi-pesticides, amayeza kunye ne-detergents, njl.
