N-methylpyrrolidone inonzi NMP kwenguva pfupi, uye chimiro chayo chemolecular ndeye c5h9no. Chirungu: 1-methyl-2-pyrrolidinone. Imvura isina ruvara kusvika kuchiedza yero inoonekera ine kakunhuhwirira kweammonia. Inosanganiswa nemvura mune chero chikamu, uye inonyungudika mune zvakasiyana-siyana zvinonyungudutsa zveorganic senge ether, acetone, esters, halogenated hydrocarbons, aromatics, etc. inenge yakasanganiswa zvachose nezvose zvinonyungudutsa mumakemikaribook. Iyo yekubikira kwayo i204 â, flash point i91 â, uye ine yakasimba hygroscopicity, yakagadzikana kemikari zvivakwa, uye haiparadze kabhoni simbi nealuminium, Inoodza zvishoma kune mhangura. Iine zvakanakira yepasi viscosity, yakanaka kemikari uye kugadzikana kwekupisa, yakakwirira polarity, kuderera kuderera, uye kusingaperi miscibility nemvura uye akawanda organic solvents. Ichi chigadzirwa idiki mushonga, uye inotenderwa muganho wekuisa mumhepo ndeye 100ppm.
