N-methylpyrrolidone, NMP; 1-methyl-2pyrrolidone; N-methyl-2-pyrrolidone. Tsis muaj xim pob tshab oily kua nrog me ntsis amine tsw. Nws yog miscible nrog dej, cawv, ethers, esters, ketones, halogenated hydrocarbons, aromatic hydrocarbons thiab castor roj. Tsawg volatility, zoo thermal thiab tshuaj stability, thiab muaj peev xwm evaporate nrog dej vapor. Nws yog hygroscopic. Sensitive rau lub teeb.
N-methylpyrrolidone yog siv dav hauv kev lag luam xws li lithium roj teeb, tshuaj, tshuaj tua kab, pigments, tshuaj ntxuav, thiab cov ntaub ntawv insulating.
Tsis muaj xim pob tshab oily kua nrog me ntsis amine tsw. Nws tuaj yeem ua rau miscible nrog dej, cawv, ether, ester, ketone, halogenated hydrocarbon thiab aromatic hydrocarbon.
1) Nws yog cov kuab tshuaj zoo heev, dav siv los ua cov extractant rau aromatics extraction, lubricating roj refining, acetylene concentration, syngas desulfurization, thiab lwm yam, thiab kuj siv nyob rau hauv industrial tu, thiab lwm yam.
2) N-methylpyrrolidone yog ib qho zoo heev extraction hnyav, dav siv raws li ib tug extractant nyob rau hauv tus txheej txheem ntawm aromatic extraction, acetylene concentration, butadiene sib cais thiab synthesis roj desulfurization. Tib lub sijhawm, Chemicalbook kuj yog tshuaj tua kab thiab engineering yas. Cov kuab tshuaj nyob rau hauv kev tsim, coatings, hluavtaws fibers, integrated circuits, thiab kuj yuav siv tau raws li industrial detergents, dispersants, dyes, lubricants, antifreeze, thiab lwm yam.
3) Dav siv nyob rau hauv qib high-grade lubricating roj refining, polymer synthesis, insulating cov ntaub ntawv, tshuaj tua kab, pigments thiab tu neeg ua hauj lwm, thiab lwm yam.
4) Cov kuab tshuaj. Organic Synthesis.
5) Siv nyob rau hauv aromatic extraction, purification ntawm acetylene, olefin, thiab diolefin; siv nyob rau hauv cov kuab tshuaj polymer thiab polymerization nruab nrab, xws li engineering yas xws li polyamide, polyimide, polyphenylene sulfide, thiab aramid fiber.
6) Siv los ua cov kuab tshuaj thiab cov extractant.
