Chaw tsim tshuaj paus Zoo Nqe N-METHYL PYRROLIDONE (NMP) CAS: 872-50-4

luv luv piav qhia:

N-Methyl Pyrrolidone yog hu ua NMP, molecular mis: C5H9NO, Lus Askiv: 1-Methyl-2-pyrrolidinone, cov tsos yog xim tsis muaj xim rau lub teeb daj pob tshab kua, me ntsis ammonia tsw, miscible nrog dej nyob rau hauv ib qho kev faib ua feem, soluble nyob rau hauv ether, acetone thiab ntau yam organic solventshal xws li aromatic esters, tov nrog hydrogen esters. tag nrho cov kuab tshuaj, boiling point 204 ℃, flash point 91 ℃, muaj zog hygroscopicity, ruaj khov tshuaj, tsis-corrosive rau carbon steel, txhuas, tooj liab me ntsis corrosive. NMP 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 organic solvents. NMP yog ib qho tshuaj micro, thiab qhov tso cai txwv tsis pub muaj nyob hauv huab cua yog 100PPM.

Kev siv ntawm NMP

N-methylpyrrolidone (NMP) yog polar aprotic hnyav. Nws muaj tsawg toxicity, siab boiling point thiab zoo solubility. Qhov zoo ntawm kev xaiv muaj zog thiab kev ruaj ntseg zoo. Dav siv nyob rau hauv aromatic hydrocarbon extraction, purification ntawm acetylene, olefins thiab diolefins, cov kuab tshuaj rau polyvinylidene fluoride, electrode auxiliary cov ntaub ntawv rau lithium ion roj teeb, syngas desulfurization, lubricating roj refining, lubricating roj antifreeze, olefin extractant, nyuaj cov khoom siv yas, cov khoom siv hluav taws xob polymer integrated circuit ntau lawm, ntxuav cov cuab yeej precision hauv kev lag luam semiconductor, Circuit Court boards, PVC tso pa roj rov qab, ntxuav cov neeg ua hauj lwm, dye auxiliaries, dispersants, thiab lwm yam. Nws kuj yog siv los ua ib qho hnyav rau polymers thiab nruab nrab rau polymerization, xws li engineering plastics thiab aramid fibers. Nws kuj tseem siv tau rau hauv tshuaj tua kab, tshuaj thiab tshuaj ntxuav. Cov kev siv tseem ceeb ntawm cov qib sib txawv ntawm N-methylpyrrolidone yog teev hauv qab no:

1. Muaj qib: lubricating roj refining, lubricating roj antifreeze, syngas desulfurization, hluav taws xob rwb thaiv tsev cov ntaub ntawv, kev ua liaj ua teb herbicides, tshuaj tua kab auxiliaries, PVC tso pa roj rov qab, auxiliaries thiab dispersants rau zus tau tej cov qib high-qib coatings, inks, pigments, thiab lwm yam vim yog lub siab solubility ntawm NMP rau resin, nws tuaj yeem siv los ua cov kuab tshuaj rau cov resin thiab Chemicalbook los siv rau hauv kev tsim cov coatings, xim av, varnishes, composite coatings, film-forming, integrated Circuit enameled wire rwb thaiv tsev cov ntaub ntawv, fiber ntau fabrics thiab adhesives thiab lwm yam khoom.

2. Ordinary qib: extraction thiab rov qab ntawm cov organic raw cov ntaub ntawv, xws li acetylene concentration thiab extraction ntawm butadiene, isoprene, aromatic hydrocarbons, thiab lwm yam. Nws yuav siv tau raws li ib tug hnyav rau recovering acetylene los ntawm natural gas los yog lub teeb naphtha thermal cracking gas, thiab purity ntawm recovering concentrated acetylene 97%. Raws li cov extractant rau kev sib cais thiab rov zoo siab-purity butadiene los ntawm tawg C4 hydrocarbons, tus nqi rov qab tuaj yeem ncav cuag 97%. %, lub purity ntawm recovered butadiene yog 99.7%, thiab nws yog siv raws li ib tug extractant rau recovering high-purity isoprene nyob rau hauv cracking C5 hydrocarbons, thiab lub rov qab purity ntawm isoprene mus txog 99%; Thaum nws yog siv los ua ib qho extractant rau aromatic hydrocarbons, nws muaj solubility siab rau aromatic hydrocarbons. Nrog tsawg vapor siab, qhov poob tus nqi ntawm extractant yog tsawg thiab tus nqi rov qab ntawm aromatics yog siab.

3. Reagent qib: Degreasing, degreasing, dewaxing, polishing, tiv thaiv xeb, xim stripping, thiab lwm yam hauv kev lag luam uas xav tau kev tswj xyuas nruj ntawm cov hlau ions thiab microparticles hauv kev sib xyaw ua ke, cov khoom siv hard disk, thiab lwm yam. thiab cov kuab tshuaj uas tsim nyob rau hauv kev lag luam kws tshuaj xws li dag lub raum ua haujlwm membrane kua, seawater desalination membrane kua, thiab lwm yam.
