N-METHYL PYRROLIDONE (NMP), amata ya molekuline: C5H9NO, Icyongereza ： 1-Methyl-2-pyrrolidinone, ibara ritagira ibara ryumuhondo risukuye, impumuro ya amoniya nkeya, itabangamiwe namazi muburyo ubwo aribwo bwose, yashonga muri etil ether, acetone, ester, hydrocarubone ya hydrogène, hydrocarbone nizindi nganda. ibishishwa, Hafi ya byose byuzuza byuzuye Igitabo cya Shimi, kuvanga ingingo 204 ℃, flash point 91 ℃, hygmoscopique, gutuza imiti, nta kwangirika kwicyuma cya karubone, aluminium, kwangirika gato kumuringa.Ifite ibyiza byo kutagira ubukonje buke, imiti myiza ihagaze neza hamwe nubushyuhe bwumuriro, polarite nyinshi, ihindagurika rito, hamwe no kutagira umupaka bitagira ingano hamwe namazi menshi.Iki gicuruzwa nibiyobyabwenge byoroheje, kwemererwa kugabanya ikirere ni 100PPM.
Ibyiza n'umutekano:
1. Amazi adafite ibara, uburyohe bwa ammonia, uburozi buke bwiki gicuruzwa.Irashobora gushonga hamwe namazi, gushonga mumashanyarazi menshi nka ether na acetone.Irashobora gushonga ibintu byinshi kama nimborera, imyuka ya polar, ibinyabuzima bisanzwe hamwe nubukorikori.
2. Imiterere yimiti: ugereranije neza mubisubizo bitabogamye.Nyuma yamasaha 8 ya 4% yumuti wa sodium hydroxide, 50% ~ 70% ya hydrolysis yabaye.Hydrolysis iboneka muri concentrated kandi ikabyara aside-meth 4 meth.Bitewe nigisubizo cya cymbal base, irashobora kubyara ketone cyangwa sulfurboline.
3. Kubaho kwa catalizike ya alkaline, igira ingaruka za olefin, kandi reaction ya alkylated iba kumwanya wa gatatu.N-methylporide ni alkaline nkeya kandi irashobora kubyara umunyu hydrochloride.Yakoze hamwe n'umunyu uremereye, nko gushyushya nikel bromide kugeza kuri 150 ℃, kubyara NIBR2 (C5H9ON) 3, hamwe no gushonga kwa 105 ℃.
Uburyo bwo gukora:Byabonetse kubisubizo bivuye kuri γ-butthochroditettes na methylemine.Intambwe yambere ya reaction nugukora 4-hydroxyl-N-methyl-base amine ya γ-butthlor na methylide, naho intambwe ya kabiri noneho ikabura umwuma kugirango ikore N-methylpidohone.Intambwe ebyiri reaction irashobora gukorwa kumurongo muri reaction ya tube.Γ-butthole ni 1: 1.15, umuvuduko ni 6MPa, n'ubushyuhe ni 250 ° C. Nyuma yo kubyitwaramo birangiye, ibicuruzwa byarangiye bibonwa no gusibanganya no gutesha umutwe.Igipimo cyinjiza ni 90%.Niba isafuriya irwanya ChemicalBook yakozwe, ingano ya methylmine ikubye inshuro 1.5-2.5, kandi gutegura laboratoire bikoreshwa nkurugero.Muri 500ml hydropower, 2mol γ-butterotone na 4 ya Moore yongeweho gufungwa no gushyuha bifunze kuri 280 ° C kuri 4h.Nyuma yo gukonjesha, kurekura methamine ikabije, kuyungurura, gukusanya ingingo ya 201-202 ° C, kubona ibicuruzwa hafi 180g, kandi amafaranga azinjiza agera kuri 90%.Gukoresha ibikoresho bibisi (kg / g) γ-butthoboretin 980 methyline (40%) 860.
Gukoresha no kubika:
1. Uburyo bwo kubika
Bika munsi ya gaze yumye, komeza ibikoresho, kandi ubike ahantu hakonje kandi humye.
2. Ibikorwa byo kwirinda
Irinde guhura: Ugomba kubona ubuyobozi bwihariye mbere yo gukoresha.Irinde guhura n'uruhu n'amaso.Irinde guhumeka umwuka n'umwotsi.Ntukegere inkomoko yumuriro.-Ntabwo kunywa itabi.Fata ingamba zo gukumira kwirundanya neza.
3. Kwirinda kubika
Hano hari ahantu heza mububiko.Gumisha kontineri hanyuma ubike ahantu humye kandi uhumeka.Igikoresho gifunguye kigomba gufungwa neza kandi kigakomeza guhagarara kugirango wirinde kumeneka.Kurandura ibidukikije byokongejwe byoroshye nubushuhe。
