N-Methylpyrrolidone: Kev siv thiab kev sib xyaw ua ke
N-Methylpyrrolidone, luv luv li NMP, muaj cov qauv molecular ntawm C5H9NO thiab paub tias yog 1-Methyl-2-pyrrolidinone hauv lus Askiv. Nws zoo nkaus li tsis muaj xim rau lub teeb daj pob tshab kua nrog me ntsis ammonia tsw. Nws yog miscible nrog dej nyob rau hauv ib qho kev faib ua feem thiab soluble nyob rau hauv ntau yam organic solvents xws li ether, acetone, esters, halogenated hydrocarbons, thiab aromatic hydrocarbons. Nws tuaj yeem sib xyaw ua ke nrog yuav luag tag nrho cov kuab tshuaj. Nws qhov kub kub yog 204℃thiab flash point yog 91 degree. Nws muaj zog noo noo nqus, ruaj khov khoom, thiab tsis-corrosive rau carbon steel thiab txhuas, tab sis me ntsis corrosive rau tooj liab. Nws boasts zoo xws li tsis tshua muaj viscosity, zoo tshuaj thiab thermal stability, siab polarity, tsawg volatility, thiab infinite miscibility nrog dej thiab ntau organic solvents. Cov khoom no tau muab cais ua cov tshuaj lom me me, nrog rau qhov tso cai txwv tsis pub tshaj 100PPM hauv huab cua.
Physicochemical zog
N-methylpyrrolidone yog cov xim tsis muaj xim rau lub teeb daj pob tshab nrog cov ntxhiab tsw me ntsis ammonia. Nws yog miscible nrog dej nyob rau hauv ib qho kev faib ua feem thiab soluble nyob rau hauv ntau yam organic solvents xws li ether, acetone, esters, halogenated hydrocarbons, thiab aromatic hydrocarbons. Nws sib tov yuav luag tag nrho cov kuab tshuaj. Nws yog qhov ruaj khov hauv cov kev daws teeb meem nruab nrab; nws maj mam hydrolyzes nyob rau hauv concentrated hydrochloric acid los tsim 4-methylaminobutyric acid.
Daim ntawv thov
N-Methylpyrrolidone (NMP) yog cov kuab tshuaj polar aprotic. Nws muaj qhov zoo xws li tsis tshua muaj toxicity, kub kub taw tes, superior solubility, muaj zog xaiv, thiab zoo stability. Nws yog dav siv nyob rau hauv extraction ntawm aromatic hydrocarbons, purification ntawm acetylene, olefins, thiab dienes, raws li ib tug hnyav rau polyvinylidene fluoride, raws li ib tug electrode auxiliary khoom rau lithium - ion roj teeb, nyob rau hauv desulfurization ntawm synthesis gas, refining ntawm lubricating agents, lubricating agents, antifreeze oils. Cov kuab tshuaj thaum lub sij hawm polymerization ntawm insoluble engineering plastics, tshuaj tua kab mob ua liaj ua teb, cov ntaub ntawv insulating, kev tsim hluav taws xob sib xyaw, kev tu cov cuab yeej precision thiab Circuit Court boards hauv kev lag luam semiconductor, PVC tail gas rov qab, ntxuav cov neeg ua hauj lwm, dye auxiliaries, dispersants, thiab lwm yam. Tsis tas li ntawd, nws tuaj yeem siv rau hauv tshuaj tua kab, tshuaj, thiab tshuaj ntxuav.
