N-METHYL PYRROLIDONE (NMP) hmoovCov mis mos molecular: C5H9NO, Lus Askiv: 1-Methyl-2-pyrrolidinone, tsis muaj xim rau daj daj pob tshab kua, me ntsis ammonia tsw, miscible nrog dej nyob rau hauv ib qho kev faib ua feem, yaj nyob rau hauv ethyl ether, acetone, ester, halogenated hydrocarbon, aromatic hydrocarbons thiab lwm yam organic. Cov kuab tshuaj, Yuav luag tag nrho cov kuab tshuaj ua tiav Chemicalbook mix, boiling point 204 ℃, flash point 91 ℃, hygmoscopic, tshuaj stability, tsis muaj corrosion rau carbon steel, txhuas, me ntsis corrosive rau tooj liab.Nws muaj qhov zoo ntawm cov viscosity tsawg, zoo tshuaj stability thiab thermal stability, siab polarity, tsis tshua muaj volatility, thiab infinite miscibility nrog dej thiab ntau cov organic solvents.Cov khoom no yog cov tshuaj me me, qhov tso cai txwv tsis pub muaj nyob hauv huab cua yog 100PPM.
Cov khoom thiab stability:
1. Colorless kua, ammonia tsw, tsis muaj toxicity ntawm cov khoom no.Nws tuaj yeem soluble nrog dej, soluble hauv feem ntau cov kuab tshuaj organic xws li ether thiab acetone.Nws tuaj yeem yaj feem ntau cov organic thiab inorganic tebchaw, polar gases, ntuj thiab hluavtaws polymer tebchaw.
2. Chemical zog: kuj ruaj khov nyob rau hauv nruab nrab tov.Tom qab 8 teev ntawm 4% ntawm sodium hydroxide tov, 50% ~ 70% ntawm hydrolysis tshwm sim.Hydrolysis tshwm sim hauv cov concentrates thiab tsim 4-meth aminocyl acid.Vim yog cov tshuaj tiv thaiv ntawm lub hauv paus cymbal, nws tuaj yeem tsim ketone lossis sulfurboline.
3. Nyob rau hauv lub hav zoov ntawm alkaline catalysts, nws muaj cov nyhuv ntawm olefin, thiab cov tshuaj tiv thaiv alkylated tshwm sim nyob rau hauv peb qhov chaw.N-methylporide tsis muaj zog alkaline thiab tuaj yeem tsim cov ntsev hydrochloride.Tsim ib qho kev sib xyaw nrog cov hlau hnyav ntsev, xws li cua sov nrog npib tsib xee bromide rau 150 ℃, tsim NIBR2 (C5H9ON) 3, thiab lub melting point ntawm 105 ℃.
Txoj kev tsim khoom:Nws yog tau los ntawm cov tshuaj tiv thaiv los ntawm γ-butthochroditettes thiab methylamine.Thawj kauj ruam ntawm cov tshuaj tiv thaiv yog los tsim 4-hydroxyl-N-methyl-base amine rau γ-butthlor thiab methylide, thiab cov kauj ruam thib ob yog tom qab lub cev qhuav dej los tsim N-methylpidohone.Cov tshuaj tiv thaiv ob-kauj ruam tuaj yeem ua nyob rau hauv kab hauv lub raj reactor.Lub γ-butthole yog 1: 1.15, lub siab yog li 6MPa, thiab qhov kub thiab txias yog 250 ° C. Tom qab cov tshuaj tiv thaiv tiav, cov khoom tiav yog tau los ntawm cov concentrated thiab decompression distillation.Cov nyiaj tau los yog 90%.Yog hais tias lub hwj chim los tiv thaiv ChemicalBook yog tsim, tus nqi ntawm methylmine yog 1.5-2.5 npaug ntawm qhov theoretical npaum li cas, thiab cov kev npaj hauv chav kuaj yog siv los ua piv txwv.Ntawm 500ml hydropower, 2mol γ-butterotone thiab 4 Moore kua yog ntxiv rau kaw thiab rhuab kaw ntawm 280 ° C rau 4h.Tom qab txias, tso cov methamine ntau dhau, distillation, sau 201-202 ° C distillation ntsiab lus, tau txog 180g ntawm cov khoom, thiab cov nyiaj tau los yuav tsum yog li 90%.Cov khoom siv raw (kg / g) γ-butthoboretin 980 methyline (40%) 860.
Kev ua haujlwm thiab ruaj khov:
1. Txoj kev khaws cia
Khaws rau hauv qab cov roj inert qhuav, khaws lub ntim ntim, thiab khaws cia rau hauv qhov chaw txias thiab qhuav.
2. Kev ceev faj ua haujlwm
Tsis txhob raug: Koj yuav tsum tau txais kev taw qhia tshwj xeeb ua ntej siv.Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag.Tsis txhob nqus pa thiab pa taws.Tsis txhob mus ze ntawm qhov hluav taws kub.- Tsis haus luam yeeb.Siv cov kev ntsuas los tiv thaiv cov khoom zoo li qub.
3. Kev ceev faj cia
Muaj ib qho chaw txias cia.Khaws lub thawv kaw thiab khaws cia rau hauv qhov chaw qhuav thiab qhov cua.Lub thawv qhib yuav tsum tau ua tib zoo kaw thiab tuav txoj haujlwm ntsug kom tiv thaiv kom tsis txhob yaig.Tshem tawm ntawm inflatable preservation yog rhiab rau cov av noo.
