N-methylpyrrolidone yog hu ua NMP, molecular mis: C5H9NO, Lus Askiv: 1-Methyl-2-pyrrolidinone, zoo li tsis muaj xim rau lub teeb daj pob tshab kua, me ntsis tsw ntawm ammonia, miscible nrog dej nyob rau hauv ib qho kev faib ua feem, soluble nyob rau hauv ether, acetone. Thiab ntau yam organic solvents xws li esters, halogenated hydrocarbons, aromatic hydrocarbons, thiab lwm yam, nws yog tag nrho cov tshuaj tov nrog yuav luag tag nrho cov kuab tshuaj, nrog ib tug boiling point ntawm 204 ° C thiab ib tug flash point ntawm 91 ° C. Nws muaj zog hygroscopicity thiab ruaj khov tshuaj. Nws tsis corrode carbon steel thiab aluminium, thiab tsis-corrosive rau tooj liab. Me ntsis corrosive. Nws muaj qhov zoo ntawm cov viscosity tsawg, tshuaj zoo thiab thermal stability, siab polarity, tsis tshua muaj volatility, thiab unlimited miscibility nrog dej thiab ntau cov organic solvents. Cov khoom no yog cov tshuaj micro, thiab qhov tso cai txwv tsis pub muaj nyob hauv huab cua yog 100PPM.

Lub cev thiab tshuaj lom neeg cov khoom N-methylpyrrolidone yog xim tsis muaj xim rau lub teeb daj pob tshab kua nrog cov ntxhiab 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 thiab esters, halogenated hydrocarbons, Chemicalbook aromatics, thiab lwm yam., yuav luag sib tov tag nrho cov kuab tshuaj. Nws yog qhov ruaj khov nyob rau hauv nruab nrab tov; nws maj mam hydrolyzes hauv cov concentrated hydrochloric acid los tsim 4-methylaminobutyric acid.

Lub hom phiaj N-methylpyrrolidone (NMP) yog polar aprotic hnyav. Nws muaj tsawg toxicity, siab boiling point thiab zoo heev solubility. Qhov zoo ntawm kev xaiv muaj zog thiab zoo stability. Dav siv nyob rau hauv aromatic hydrocarbon extraction, purification ntawm acetylene, olefins thiab dienes, hnyav rau polyvinylidene fluoride, electrode auxiliary cov ntaub ntawv rau lithium-ion roj teeb, syngas desulfurization, lubricating roj refining, lubricating roj antifreeze, Chemicalbook olefin extraction tus neeg saib xyuas, insoluble engineering plastics, tshuaj tua kab mob ua liaj ua teb, cov ntaub ntawv rwb thaiv tsev, kev tsim hluav taws xob sib xyaw ua ke, kev tu cov cuab yeej precision thiab Circuit Court boards hauv kev lag luam semiconductor, PVC tso pa rov qab, tshuaj ntxuav, dye additives, dispersants, thiab lwm yam. Nws kuj yog siv los ua cov kuab tshuaj polymers thiab nruab nrab rau cov tshuaj tiv thaiv polymerization, xws li engineering plastics thiab aramid fibers. Tsis tas li ntawd, nws tseem tuaj yeem siv rau hauv tshuaj tua kab, tshuaj thiab tshuaj detergents, thiab lwm yam.
