N-Methyl-2-pyrrolidinone(NMP) Cas:872-50-4
I-N- methylpyrrolidone, ulwelo olunamafutha olungenambala noluselubala olunevumba le-amine elincinci.Inyibilika ngamanzi, utywala, i-ether, i-ester, iketone, ihalogenated hydrocarbon, i-hydrocarbon enuka kamnandi kunye neoyile yecastor.Ukuguquguquka okuphantsi, ukuzinza okuhle kwe-thermal kunye nokuzinza kweekhemikhali, kwaye kunokunyuka ngomphunga wamanzi.Yiba ne-hygroscopicity.Inovakalelo ekukhanyeni.
I-N-methylpyrrolidone isetyenziswa ngokubanzi kwibhetri ye-lithium, iyeza, i-pesticide, i-pigment, i-agent yokucoca, i-insulating material kunye namanye amashishini.

Ukhuseleko oluyityhefu
Ukucaphuka kancinci eluswini, kodwa akukho ukufunxa.Ngenxa yoxinzelelo oluphantsi lomphunga, ingozi yokuphefumla enye incinci kakhulu.Nangona kunjalo, iziphumo ezingapheliyo zinokubangela ukungasebenzi kakuhle kwenkqubo ye-nervous central, ebangela izifo zezitho zokuphefumula, izintso kunye neenkqubo ze-vascular.Iigundane ziphefumle lo mphunga wemveliso kwiiyure ze-2 kwi-concentration ye-0.18 ~ 0.20mg / L, enokubangela ukucaphuka okuncinci kwindlela yokuphefumula ephezulu kunye namehlo.I-LD50 yeegundane kunye neegundane yayiyi-5200 mg / kg kunye ne-7900mg / kg ngokulandelanayo.Ugxininiso oluphezulu oluvumelekileyo kwindawo yokusebenza yi-100mg/m3.Abasebenzi abakwisiza kufuneka banxibe iimaski, iiglasi ezikhuselayo kunye neeglavu.
Ukupakishwa, ukugcinwa kunye nokuthutha Le mveliso ayisebenzi kwiipropati zeekhemikhali kwaye ayinayo i-corrosion kwezinye izinyithi ezifana ne-carbon steel kunye ne-aluminium ngaphandle kobhedu.Ipakishwe kwimigqomo yentsimbi, i-50kg okanye i-100kg ngegubu ngalinye, kwaye iipakethe ezincinci zipakishwe kwiibhotile zeglasi ukuphepha ukukhanya.Gcina kwaye uthuthe ngokwemigaqo yekhemikhali ngokubanzi.
