N-methylpyrrolidone inonzi NMP, molecular formula: C5H9NO, Chirungu: 1-Methyl-2-pyrrolidinone, chitarisiko chisina ruvara kusvika kuchiedza chero chinopenya mvura, kunhuhwirira zvishoma kweammonia, kusanganiswa nemvura mune chero chikamu, inonyungudika muether, acetone. Uye zvakasiyana-siyana organic solvents senge esters, halogenated hydrocarbons, aromatic hydrocarbons, zvichingodaro, inosanganiswa nemakemikari neinenge yese zvinonyungudutsa, ine kuvira kwe204 ° C uye flash point ye91 ° C. Iyo ine yakasimba hygroscopicity uye yakagadzikana makemikari ehupfumi. Iyo haiparadze kabhoni simbi uye aruminiyamu, uye haina-kuora kumhangura. Inoita ngura. Iine zvakanakira yepasi viscosity, yakanaka kemikari uye kugadzikana kwekupisa, yakakwirira polarity, kuderera kuderera, uye kusingagumi miscibility nemvura uye akawanda organic solvents. Ichi chigadzirwa idiki-mushonga, uye inotenderwa muganho wekuisa mumhepo ndeye 100PPM.

Muviri uye makemikari zvivakwa N-methylpyrrolidone imvura isina ruvara kusvika kuyero inoonekera uye ine kakunhuhwirira kweammonia. Inosanganiswa nemvura mune chero chikamu uye inonyungudika mune dzakasiyana siyana organic zvinonyungudutsa senge ether, acetone uye esters, halogenated hydrocarbons, Chemicalbook aromatics, nezvimwewo, zvinenge Sanganisa zvakakwana nezvose zvinonyungudutsa. Iyo yakanyatsogadzikana mukusarerekera mhinduro; iyo zvishoma nezvishoma inokonzera hydrolyze mu concentrated hydrochloric acid kuti ibudise 4-methylaminobutyric acid.

Chinangwa N-methylpyrrolidone (NMP) is polar aprotic solvent. Iyo ine yakaderera toxicity, yakakwirira yekubikira nzvimbo uye yakanakisa solubility. Zvakanakira kusarudza kwakasimba uye kugadzikana kwakanaka. Inoshandiswa zvakanyanya mukunhuhwirira kwehydrocarbon kubviswa, kucheneswa kweacetylene, olefins uye dienes, solvent ye polyvinylidene fluoride, electrode anobatsira mabhatiri e lithium-ion mabhatiri, syngas desulfurization, mafuta ekuzora, mafuta ekuzora antifreeze, Chemicalbook olefin extraction agent ye polymer, Solvent. insoluble engineering mapurasitiki, mishonga yekurima yemishonga, yekudzivirira, yakasanganiswa yedunhu kugadzirwa, kucheneswa kweiyo chaiyo zviridzwa uye edunhu mabhodhi muindasitiri yesemiconductor, PVC inopedza gasi kupora, kuchenesa maajenti, dhayi zvinowedzera, dispersants, etc. Inoshandiswawo sechinhu chinonyungudutsa chepolymers. uye svikiro rekuita kwepolymerization, senge engineering mapurasitiki uye aramid fibers. Mukuwedzera, inogonawo kushandiswa mumishonga yezvipembenene, mishonga uye detergents, nezvimwewo.
