N-METHYL PYRROLIDONE (NMP), molecular formula :C5H9NO, Chirungu:1-Methyl-2-pyrrolidinone, isina ruvara kusvika kuyero inoonekera mvura, kunhuhwirira kweammonia zvishoma, kusanganiswa nemvura mune chero chikamu, yakanyungudutswa mu ethyl ether, acetone, ester, halogenated hydrocarbon, anonhuwirira hydrocarbons uye mamwe organic zvinonyungudutsa, Zvinenge zvese zvinonyungudutsa zvinokwana Chemicalbook musanganiswa, 204 ℃, flash point 91 ℃, hygmoscopic, kugadzikana kwemakemikari, hapana ngura kune kabhoni simbi, aruminiyamu, inoodza zvishoma kune mhangura.Iine zvakanakira yepasi viscosity, yakanaka kugadzikana kwemakemikari uye kugadzikana kwekupisa, yakakwirira polarity, kuderera kuderera, uye kusingaperi miscibility nemvura uye akawanda organic solvents.Ichi chigadzirwa mushonga munyoro, inotenderwa muganho wekuisa mumhepo ndeye 100PPM.
Properties uye kugadzikana:
1. Mvura isina ruvara, ammonia flavour, low toxicity yechigadzirwa ichi.Inogona kunyungudika nemvura, inonyungudika mune zvakawanda organic solvents senge ether uye acetone.Inogona kunyungudutsa akawanda organic uye inorganic komisheni, polar magasi, echisikigo uye ekugadzira polymer makomisheni.
2. Chemical properties: yakanyatsogadzikana mune neutral solution.Mushure memaawa masere e4% yesodium hydroxide solution, 50% ~ 70% yehydrolysis yakaitika.Hydrolysis inoitika muconcentrates uye inogadzira 4-meth aminocyl acid.Nekuda kwekuita kweiyo cymbal base, inogona kugadzira ketone kana sulfurboline.
3. Muhupo hwe alkaline catalysts, ine mhedzisiro yeolefin, uye alkylated reaction inoitika munzvimbo yechitatu.N-methylporide haina kusimba alkaline uye inogona kugadzira munyu hydrochloride.Yakagadzira yakabatanidzwa neheavy metal munyu, sekudziya ne nickel bromide kusvika 150 ℃, ichigadzira NIBR2(C5H9ON)3, uye nzvimbo yekunyungudika ye105℃.
Nzira yekugadzira:Inowanikwa nekuita kubva ku-γ-butthochroditettes uye methylemine.Danho rekutanga rekuita ndere kugadzira 4-hydroxyl-N-methyl-base amine ye γ-butthlor uye methylide, uye nhanho yechipiri inobva yapera mvura kuti igadzire N-methylpidohone.Maitiro maviri-matanho anogona kuitwa mumutsara muchubhu reactor.Iyo γ-butthole ndeye 1: 1.15, kudzvinyirira kunenge 6MPa, uye kutonhora kuri 250 ° C. Mushure mokunge mhinduro yacho yapera, chigadzirwa chakapedzwa chinowanikwa nekugadziriswa uye decompression distillation.Chiyero chemari i90%.Kana iyo kettle anti-ChemicalBook inogadzirwa, huwandu hwemethylmine ndeye 1.5-2.5 nguva iyo theoretical huwandu, uye gadziriro yerabhoritari inoshandiswa semuenzaniso.Pakati pe500ml hydropower, 2mol γ-buterotone uye 4 Moore mvura inowedzerwa kuti ivharwe uye inopisa yakavharwa pa280 ° C kwe4h.Mushure mekutonhodza, buritsa yakawandisa methamine, distillation, unganidza 201-202 ° C distillation mapoinzi, tora anenge 180g ezvigadzirwa, uye mari inowanikwa inenge 90%.Raw zvinhu kushandiswa (kg/g) γ-butthoboretin 980 methyline (40%) 860.
Kushanda uye kuchengetedza:
1. Nzira yekuchengetedza
Chengetedza pasi pegasi yakaoma inert, chengetedza mudziyo wakavharwa, uye chengeta munzvimbo inotonhorera uye yakaoma.
2. Maitiro ekudzivirira
Dzivisa kuratidzwa: Unoda kuwana nhungamiro yakakosha usati washandisa.Dzivisa kusangana neganda nemaziso.Dzivisa inhalation yemhute uye utsi.Usaswedere panobva moto.-Kwete kuputa.Tora matanho ekudzivirira static kuunganidza.
3. Kuchengetedza kuchengetedza
Pane nzvimbo inotonhorera mukuchengetedza.Chengetedza mudziyo wakavharwa uye chengeta munzvimbo yakaoma uye ine mhepo.Chigaba chakashama chinofanira kunyatsovharwa uye chengetedza nzvimbo yakatwasuka kudzivirira kubuda.Kubvisa inflatable kuchengetedza kunonzwa kune humidity.
