I-N-Methyl-2-pyrrolidinone(NMP) Cas:872-50-4
I-N- methylpyrrolidone, uketshezi olunamafutha angenambala futhi olusobala olunephunga elincane le-amine.Incibilika ngamanzi, utshwala, i-ether, i-ester, i-ketone, i-halogenated hydrocarbon, i-hydrocarbon enuka kamnandi namafutha e-castor.Ukuntengantenga okuphansi, ukuzinza okuhle kokushisa kanye nokuzinza kwamakhemikhali, futhi kungahwamuka ngomhwamuko wamanzi.Yiba ne-hygroscopicity.Kuyazwela ekukhanyeni.
I-N-methylpyrrolidone isetshenziswa kabanzi kubhethri ye-lithium, umuthi, isibulala-zinambuzane, i-pigment, i-ejenti yokuhlanza, i-insulating material nezinye izimboni.

Ukuvikelwa okunobuthi
Ukucasuka kancane esikhumbeni, kodwa akukho ukumuncwa.Ngenxa yomfutho we-steam ophansi, ingozi yokuhogela okukodwa incane kakhulu.Kodwa-ke, imiphumela engapheli ingabangela ukungasebenzi kwesimiso sezinzwa esiyinhloko, okubangela izifo zezitho zokuphefumula, izinso nezinhlelo ze-vascular.Amagundane ahogele lo mhwamuko womkhiqizo amahora angu-2 ekuhlanganiseni okungu-0.18~0.20mg/L, okungase kubangele ukucasuka okuncane emgudwini wokuphefumula ongaphezulu namehlo.I-LD50 yamagundane namagundane yayiyi-5200 mg/kg kanye ne-7900mg/kg ngokulandelana.Isilinganiso esiphezulu esivumelekile emsebenzini ngu-100mg/m3.Abasebenza endaweni kufanele bagqoke imaski, izibuko zokuzivikela kanye namagilavu.
Ukupakishwa, ukugcinwa kanye nokuthutha Lo mkhiqizo awusebenzi kumakhemikhali futhi awugqwali kwezinye izinsimbi njenge-carbon steel ne-aluminium ngaphandle kwethusi.Ipakishwa ezigubhu zensimbi, 50kg noma 100kg isigubhu ngasinye, futhi amaphakheji amancane apakishwa emabhodleleni engilazi ukugwema ukukhanya.Gcina futhi uthuthe ngokwemithetho ejwayelekile yamakhemikhali.
