N-methylpyrrolidone waxaa loo tixraacaa sida NMP, qaacidada kelli: C5H9NO, Ingiriisi: 1-Methyl-2-pyrrolidinone, muuqaalku waa mid aan midab lahayn oo dareeraha huruuda ah ee huruud ah, wax yar oo urta ammonia, oo lagu qasi karo biyo qayb kasta, oo ku milma ether, acetone Iyo dareerayaasha kala duwan ee dabiiciga ah sida esters, hydrocarbons halogenated, hydrocarbons udgoon, iwm, waxaa si buuxda loogu daray kiimiko ahaan ku dhawaad ​​dhammaan dareerayaasha, oo leh barta karkaraya ee 204 ° C iyo barta toosan ee 91 ° C. Waxay leedahay hygroscopicity xooggan iyo sifooyin kiimiko oo deggan. Ma daxaleeyo birta kaarboonka iyo aluminiumka, mana aha mid daxalaysa ilaa naxaasta. Wax yar daxaloobay. Waxay leedahay faa'iidooyinka viscosity hoose, kiimiko wanaagsan iyo xasilloonida kulaylka, polarity sare, isbeddel hoose, iyo miscibility aan xad lahayn oo leh biyo iyo dareerayaal badan oo organic. Alaabtani waa dawo-yar, iyo xadaynta xaddidan ee hawadu waa 100PPM.

Qalabka jirka iyo kiimikaad N-methylpyrrolidone waa dareere hufan oo huruud ah oo aan midab lahayn oo leh ur yar oo ammonia ah. Waxay ku milmi kartaa biyaha qayb kasta waxayna ku milmaysaa dareerayaasha kala duwan ee organic sida ether, acetone iyo esters, hydrocarbons halogenated, aromatics buuga kiimikaad, iwm, ku dhawaad ​​si fiican ugu qas dhammaan dareerayaasha. Way xasilloon tahay xal dhexdhexaad ah; waxay si tartiib tartiib ah u soo saartaa hydrochloric acid si ay u dhaliso 4-methylaminobutyric acid.

Muuqashada dareere hufan oo aan midab lahayn (ka sarreeya 25 ℃)
daahirnimo% ≥99.5
Qoyaanka% ≤0.1
Chroma HaZen ≤25
Tusmada dib-u-celinta N20D 1.468-1.471

Ujeedada N-methylpyrrolidone (NMP) waa dareere aprotic polar ah. Waxay leedahay sunta hoose, barta karkarinta sare iyo milanka aad u fiican. Faa'iidooyinka xulashada xooggan iyo xasilloonida wanaagsan. Si ballaaran loo isticmaalo soo saarista hydrocarbon udgoon, nadiifinta acetylene, olefins iyo dienes, dareeraha polyvinylidene fluoride, qalabka caawinta electrode ee baytariyada lithium-ion, desulfurization syngas, sifaynta saliidda, saliidayn antifreeze saliid, Kiimikadabook olefin wakiilka soo saarista, Xalalka polymerization balaastikada injineernimada aan la milmi karin, dhirta dhirta, alaabta dahaadhka, wax soo saarka wareegga isku dhafan, nadiifinta qalabka saxda ah iyo guddiyada wareegga ee warshadaha semiconductor, soo kabashada gaasta PVC, wakiilada nadiifinta, daroogooyinka dheeha, kala firdhinta, iwm. Waxa kale oo loo isticmaalaa sida dareeraha polymers iyo dhexdhexaad ah falcelinta polymerization, sida balaastikada injineernimada iyo fiilooyinka aramid. Intaa waxaa dheer, waxaa sidoo kale loo isticmaali karaa sunta cayayaanka, daawooyinka iyo saabuunta, iwm.
