N-methylpyrrolidone yog hu ua NMP, cov mis molecular: C5H9NO, Lus Askiv: 1-Methyl-2-pyrrolidinone, tsos yog xim tsis muaj xim rau lub teeb daj pob tshab kua, me ntsis tsw ntawm ammonia, miscible nrog dej hauv txhua qhov sib piv, soluble hauv ether, acetone Thiab ntau yam organic solvents xws li esters, halogenated hydrocarbons, aromatic hydrocarbons, thiab lwm yam., nws yog sib xyaw ua ke nrog yuav luag txhua cov kuab tshuaj, nrog lub ntsiab lus kub ntawm 204 ° C thiab lub ntsiab lus flash ntawm 91 ° C. Nws muaj zog hygroscopicity thiab ruaj khov tshuaj lom neeg. Nws tsis corrode carbon hlau thiab txhuas, thiab tsis yog corrosive rau tooj liab. Me ntsis corrosive. Nws muaj qhov zoo ntawm viscosity qis, tshuaj lom neeg zoo thiab thermal stability, polarity siab, volatility qis, thiab unlimited miscibility nrog dej thiab ntau yam organic solvents. Cov khoom no yog ib qho micro-tshuaj, thiab qhov tso cai txwv concentration hauv huab cua yog 100PPM.

Cov khoom siv lub cev thiab tshuaj lom neeg N-methylpyrrolidone yog cov kua tsis muaj xim rau lub teeb daj nrog me ntsis tsw ntawm ammonia. Nws yog miscible nrog dej hauv txhua qhov sib piv thiab soluble hauv ntau yam organic solvents xws li ether, acetone thiab esters, halogenated hydrocarbons, Chemicalbook aromatics, thiab lwm yam, yuav luag sib tov kom huv si nrog txhua cov kuab tshuaj. Nws ruaj khov nyob rau hauv cov kua nruab nrab; nws maj mam hydrolyzes nyob rau hauv concentrated hydrochloric acid los tsim 4-methylaminobutyric acid.

Lub Hom Phiaj N-methylpyrrolidone (NMP) yog cov tshuaj yaj aprotic polar. Nws muaj cov tshuaj lom tsawg, qhov kub siab thiab solubility zoo heev. Qhov zoo ntawm kev xaiv muaj zog thiab kev ruaj khov zoo. Siv dav hauv kev rho tawm aromatic hydrocarbon, kev ntxuav acetylene, olefins thiab dienes, cov tshuaj yaj rau polyvinylidene fluoride, cov khoom siv electrode rau cov roj teeb lithium-ion, syngas desulfurization, lubricating roj refining, lubricating roj antifreeze, Chemicalbook olefin extraction agent, Cov tshuaj yaj rau polymerization ntawm cov yas engineering insoluble, cov tshuaj tua kab ua liaj ua teb, cov ntaub ntawv rwb thaiv tsev, kev tsim cov khoom siv hluav taws xob, kev ntxuav cov cuab yeej precision thiab cov laug cam hauv kev lag luam semiconductor, PVC exhaust gas rov qab, cov neeg ntxuav, cov xim ntxiv, cov dispersants, thiab lwm yam. Nws kuj tseem siv ua cov tshuaj yaj rau polymers thiab ib qho nruab nrab rau cov tshuaj tiv thaiv polymerization, xws li cov yas engineering thiab aramid fibers. Tsis tas li ntawd, nws kuj tseem siv tau rau hauv cov tshuaj tua kab, tshuaj thiab cov tshuaj ntxuav tes, thiab lwm yam.
