Nhevedzano yemakemikari ekutanga–N-methylpyrrolidone (NMP)

Zita remakemikari: N-methyl-2-pyrrolidone; 1-methyl-2-pyrrolidone; nitrogen-methylpyrrolidone.
Nhamba yeCAS: 872-50-4
Fomura yemasero: C5H9NO

Zita rechiRungu: N-methyl-2-pyrrolidone
Hunhu: N-methylpyrrolidone (NMP muchidimbu) imhando yenitrogen heterocyclic ine fomura yemamorekuru yeC5H9NO uye poindi yekufashaira ye204°C. Imvura ine hwema hushoma hweammonia. Inosanganiswa nemvura chero muyero upi zvawo uye inoenderana nezvinonyungudutsa zvese (ethanol, ethanol, Acetaldehyde, ketones, aromatic hydrocarbons, nezvimwewo) zvakasanganiswa zvizere.

NMP i polar aprotic solvent ine poiling point yakakwira, strong polarity, low viscosity, strong solubility, non-corrosion, low chepfu, strong biodegradability, low volatility, high chemical stability uye thermal stability.

Maitiro ekugadzira: NMP yagara iri maindasitiri kwenguva yakareba uye tekinoroji yacho yakura. Maitiro ayo ekugadzira anosanganisira kubvisa hydrogenation ye1,4-butanediol (BDO) kuti igadzire γ-butyrolactone (GBL), uyezve kusanganiswa kweγ-butyrolactone nemonomethylamine. Maitiro aya anogadzira zvigadzirwa, izvo zvinobva zvanyungudutswa uye zvacheneswa kuita chigadzirwa chapera cheNMP.

Nzvimbo dzekushandisa

N-Methylpyrrolidone chinhu chinonyungudutsa chemhando yepamusoro chinoshandiswa mumafuta epetrochemicals, mishonga yezvipembenene, mishonga, zvinhu zvemagetsi nedzimwe nzvimbo. Inogona kushandiswa se acetylene concentration, syngas desulfurization, lubricating oil refine, lubricating oil antifreeze, olefin extraction agent, solvent mu polymerization ye insoluble engineering plastics, agricultivar herbicides, insulation materials, integrated circuit production, PVC exhaust gas recovery, cleansing agents, dye auxiliaries, dispersants, nezvimwewo.
