N-methyl pyrrolidone (NMP)?

N-Methyl Pyrrolidone (NMP), molecular cov mis: c5h9no, Askiv: 1-methyl-2-pyrrolidinone, acetone, ester, halomenated hydrocarbon, cov ntxhiab hydrocarbons thiab lwm yam organic Cov kuab tshuaj, yuav luag txhua cov kuab tshuaj ua tiav impectook sib tov, npau tes taw 204 ℃, flash Point 91 ℃, kev lom zem, tshuaj lom neeg ruaj khov, tsis muaj xeb rau cov steel hlau, txhuas, me ntsis corrosive rau tooj liab. Nws muaj qhov zoo ntawm cov tshuaj viscosity qis, tshuaj lom neeg zoo, muaj qhov tsis sib xws, thiab ntau cov kuab tshuaj muaj organic. Cov khoom no yog cov tshuaj me, cov kev txwv uas tau tso cai hauv huab cua yog 100ppm.

Cov Khoom Siv thiab stability:

1. Cov kua tsis muaj xim, ammonia tsw, muaj kuab lom ntawm cov khoom no. Nws tuaj yeem yog soluble nrog dej, soluble nyob rau hauv feem ntau cov kuab tshuaj muaj ether thiab acetone. Nws tuaj yeem yaj cov organic thiab inorganic compound, polar gases, ntuj thiab hluavtaws polymer sib txuas.

2. Tshuaj lom neeg: sib npaug hauv nruab nrab kev daws teeb meem. Tom qab 8 teev ntawm 4% ntawm sodium hydrocide tov, 50% ~ 70% ntawm hydrolysis tau tshwm sim. Hydrolysis muaj nyob rau hauv cov kev xav thiab ua rau muaj 4-me me aminocyl acid. Vim cov tshuaj tiv thaiv ntawm cov cymbal puag, nws tuaj yeem tsim cov Ketone lossis Sulfurboline.

3. Nyob rau hauv lub neej ntawm alkaline catalysts, nws muaj qhov cuam tshuam ntawm kev siv olefin, thiab ib cov tshuaj tiv thaiv alkylated tshwm sim hauv qhov chaw thib peb. N-Methylendide yog tsis muaj zog alkaline thiab tuaj yeem tsim cov ntsev ntsev. Tsim ib qho kev sib xyaw nrog cov cua sov hlau, xws li cua sov nrog Nickel bromide rau 150 ℃, tsim Nibr2 (C5h9on) 3, thiab lub ntsiab lus melting ntawm 105 ℃.

Txujcial Ntau Lawm:Nws yog tau los ntawm cov tshuaj tiv thaiv los ntawm γ-butthochroditettes thiab methylemine. Thawj kauj ruam ntawm cov tshuaj tiv thaiv yog los tsim 4-hydroxyl-n-mthyl-base amine rau γ-butthylide, thiab lub sijhawm thib ob yog lub cev qhuav dej kom tsim cov n-methylpidohokone. Ob-kauj ruam ntawm cov tshuaj tiv thaiv tuaj yeem ua nyob rau hauv kab hauv rube reactor. The γ-Butthole yog 1: 1.15, lub siab yog hais txog 6MPA, thiab qhov ntsuas kub yog li 250 ° Cov nyiaj tau los yog 90%. Yog tias cov kais dej tawm los tiv thaiv cov tshuaj lom neeg yog tsim tawm, cov me me ntawm methylmine yog 1.5-2.5 zaug kev npaj ua kom lub chaw kuaj mob, thiab kev npaj kuaj mob yog siv ua piv txwv. Ntawm cov 500ml hydropower, 2Mol γ-butterotone thiab 4 Mooore ua kua yog ntxiv rau kaw thiab ua kom sov kaw ntawm 280 ° C rau 4H. Tom qab txias, tso tawm cov methamine ntau dhau, sau cov ntsiab lus 201-202 ° 201-202 ° 201, tau txog 180g ntawm cov khoom lag luam, thiab yuav tsum muaj li 90%. Cov Khoom Siv Raw Khoom Noj (kg / g) γ-butthoboretin 980 Methyline (40%) 860) 860) 860) 860.

Kev ua haujlwm thiab cia:

1. Kev khaws cia

Khaws nyob rau hauv cov roj av qhuav, khaws lub thawv ntim, thiab khaws cia rau hauv qhov chaw txias thiab qhuav.

2. Kev Ua Haujlwm Kev Ua Haujlwm

Zam tsis txhob raug: Koj yuav tsum tau txais cov kev qhia tshwj xeeb ua ntej siv. Zam kev sib cuag nrog tawv nqaij thiab qhov muag. Tsis txhob nqus pa ntawm vapor thiab haus luam yeeb. Tsis txhob ua raws li qhov hluav taws kub. -No haus luam yeeb. Coj kev ntsuas kom tiv thaiv tau zoo li qub.

3. Kev tiv thaiv khaws cia

Muaj qhov chaw txias hauv kev cia. Khaws lub thawv kaw thiab khaws cia rau hauv qhov chaw qhuav thiab muaj qhov cua. Lub thawv qhib yuav tsum tau ua kom zoo ib ce thiab ua kom cov kab ntsug kom tiv thaiv tsis taus. Kev tshem tawm ntawm cov khoom khaws cia tsis muaj kev tiv thaiv kom muaj av noo.
