N-METHYL PYRROLIDONE (NMP), fomura yemamorekuru :C5H9NO, Chirungu: 1-Methyl-2-pyrrolidinone, mvura isina ruvara kusvika yero, inonhuwa zvishoma yeammonia, inosanganiswa nemvura chero chikamu, yakanyungudutswa mu ethyl ether, acetone, ester, halogenated hydrocarbon, aromatic hydrocarbons nezvimwe zvinonyungudutsa zve organic, Zvinenge zvese zvinonyungudutsa zvinosanganisa Chemicalbook mix, boiling point 204℃, flash point 91℃, hygmoscopic, chemical stability, hapana corrosion ku carbon steel, aruminiyamu, inoparadza zvishoma ku copper. Ine zvakanakira low viscosity, good chemical stability uye thermal stability, high polarity, low volatility, uye isingaperi musanganiswa nemvura uye akawanda organic solvents. Chigadzirwa ichi mushonga munyoro, muganho unobvumidzwa mumhepo i100PPM.
Zvivakwa uye kugadzikana:
1. Mvura isina ruvara, kunaka kweammonia, chepfu shoma yechigadzirwa ichi. Chinogona kunyungudika nemvura, kunyungudika muzvinhu zvakawanda zvinonyungudika zvakaita se ether ne acetone. Chinogona kunyungudutsa zvinhu zvakawanda zve organic ne inorganic, magasi e polar, polymer compounds dzechisikigo nedze synthetic.
2. Hunhu hwemakemikari: hwakagadzikana zvishoma nezvishoma mumushonga usina kusimba. Mushure memaawa masere e4% ye sodium hydroxide solution, 50% ~ 70% ye hydrolysis yakaitika. Hydrolysis inoitika mu concentrates uye inogadzira 4-meth aminocyl acid. Nekuda kwekuita kwe cymbal base, inogona kugadzira ketone kana sulfurboline.
3. Kana paine alkaline catalysts, ine simba re olefin, uye alkylated reaction inoitika panzvimbo yechitatu. N-methylporide ine alkaline shoma uye inogona kugadzira munyu hydrochloride. Yakaumbwa nemunyu wesimbi wakawanda, wakadai sekupisa ne nickel bromide kusvika 150℃, ichigadzira NIBR2(C5H9ON)3, uye poindi yekunyunguduka ye105℃.
Nzira yekugadzira:Inowanikwa nekuita kubva kuγ-butthochroditettes nemethylemine. Danho rekutanga rekuita nderekugadzira 4-hydroxyl-N-methyl-base amine yeγ-butthlor nemethylide, uye danho rechipiri rinozobviswa mvura kuti rigadzire N-methylpidohone. Kuita kwematanho maviri kunogona kuitwa mumutsara mu tube reactor. γ-butthole i1: 1.15, kumanikidzwa kuri 6MPa, uye tembiricha i250 ° C. Mushure mekunge kuita kwapera, chigadzirwa chapera chinowanikwa ne concentrated uye decompression distillation. Mutengo wemari i90%. Kana kettle anti-ChemicalBook ikagadzirwa, huwandu hwemethylmine hunowedzera ka1.5-2.5 pane huwandu hwedzidziso, uye kugadzirira kwerabhoritari kunoshandiswa semuenzaniso. Pakati pe500ml hydropower, 2mol γ-butterotone uye 4 Moore liquid zvinowedzerwa kuti zvivharwe uye zvidziyirwe pa280 ° C kwemaawa mana. Mushure mekutonhodza, buritsa methamine yakawandisa, distillation, unganidza mapoinzi ekudiridza e201-202 ° C, tora anenge 180g ezvigadzirwa, uye mari yacho ichave inenge 90%. Kushandiswa kwezvinhu zvisina kucheneswa (kg/g) γ-butthoboretin 980 methyline (40%) 860.
Kushanda uye Kuchengeta:
1. Nzira yekuchengetedza
Chengeta pasi pegasi rakaoma risina kusimba, chengeta gaba rakavharirwa, uye chengeta munzvimbo inotonhorera uye yakaoma.
2. Matanho ekudzivirira mashandiro
Dzivisa kusangana nechinhu: Unofanira kuwana gwara rakakosha usati washandisa. Dzivisa kusangana neganda nemaziso. Dzivisa kufema utsi neutsi. Usaswedere pedyo nekwakabva moto. -Haufanirwe kusvuta. Tora matanho ekudzivirira kuungana kwechinhu chisina kumira zvakanaka.
3. Nzira dzekuchengetedza zvinhu
Pane nzvimbo inotonhorera yekuchengetera. Chengeta mudziyo wakavharwa wouchengeta munzvimbo yakaoma uye ine mhepo inofefetera. Mudziyo wakavhurika unofanira kuvharwa zvakanaka uye woramba wakamira kuti usadonhe. Kubviswa kwekuchengetedzwa kwemhepo kunokonzeresa hunyoro.
