Katundu:
N-Methyl-pyrrolidinone, molecular weight 99.13106, ndi organic pawiri, colorless manla mafuta madzi, pang'ono amine fungo.Imakhala ndi kusinthasintha kochepa, kutentha kwabwino komanso kukhazikika kwamankhwala, ndipo imatha kutenthedwa ndi nthunzi wamadzi.Ili ndi hygroscopicity.Zomverera ndi kuwala.Amasungunuka mosavuta m'madzi, ethanol, etha, acetone, ethyl acetate, chloroform ndi benzene, amatha kusungunula kwambiri organic ndi inorganic mankhwala, mpweya wa polar, chilengedwe ndi kupanga polima mankhwala.N-methyl pyrrolidone amagwiritsidwa ntchito kwambiri mu lithiamu, mankhwala, mankhwala ophera tizilombo, pigment , woyeretsa, zipangizo zotetezera ndi mafakitale ena.
Ntchito Yogulitsa:
O-Methyl-pyrrolidinchimodzi ndi chosungunulira chapamwamba kwambiri, chosankha komanso chokhazikika chosungunulira polar.Amagwiritsidwa ntchito kwambiri m'makampani a petrochemical, mankhwala ophera tizilombo, chithandizo chamankhwala, zida zamagetsi ndi zina.Itha kugwiritsidwa ntchito mu syngas desulphurisation, kuyenga mafuta, mafuta oletsa kuzizira, olefin extractant, herbicide yaulimi, insulating material, Integrated circuit production, pvc tail gas rearing, kuyeretsa wothandizila, utoto wothandiza, wobalalitsa ndi zina zotero.
Zolemba zogwirira ntchito:
Pewani kukhudzana: malangizo apadera amafunikira musanagwiritse ntchito.Pewani kukhudzana ndi khungu ndi maso.Pewani kutulutsa mpweya ndi mpweya.Osayandikira magwero oyatsira.Kusuta ndikoletsedwa kotheratu.Chitanipo kanthu kuti musamamangidwe.
Zolemba Zosungira:
1.Sungani pansi pa gasi wouma, wosagwira ntchito, kusunga chidebe chotsekedwa mwamphamvu.
2.Sungani pamalo ozizira.
3.Sungani chidebe chotsekedwa mwamphamvu ndikusunga pamalo owuma, olowera mpweya.
4. Zotengera zotsegulidwa ziyenera kutsekedwa bwino ndikusungidwa pamalo oongoka kuti zisatayike.
5.Kusungirako kwa mpweya kumakhudzidwa ndi chinyezi.
