N-methylpyrrolidone imatchedwa NMP, chilinganizo cha maselo: C5H9NO, Chingerezi: 1-Methyl-2-pyrrolidinone, mawonekedwe amadzimadzi owoneka bwino achikasu, fungo la ammonia pang'ono, osakanikirana ndi madzi aliwonse, amasungunuka mu ether, acetone. Ndipo zosungunulira zosiyanasiyana organic monga esters, halogenated hydrocarbons, onunkhira hydrocarbons, ndi zina zotero, ndi kwathunthu kusakaniza mankhwala pafupifupi zosungunulira zonse, ndi kuwira mfundo 204 ° C ndi kung'anima mfundo 91 ° C. Ili ndi hygroscopicity yamphamvu komanso yokhazikika yamankhwala. Siziwononga zitsulo za carbon ndi aluminiyamu, ndipo siziwononga mkuwa. Zowononga pang'ono. Zili ndi ubwino wa kukhuthala kochepa, kukhazikika kwa mankhwala ndi kutentha kwabwino, polarity yapamwamba, kusasunthika kochepa, komanso kusamvana kopanda malire ndi madzi ndi zosungunulira zambiri za organic. Izi ndi mankhwala ang'onoang'ono, ndipo malire ovomerezeka mlengalenga ndi 100PPM.

Thupi ndi mankhwala katundu N-methylpyrrolidone ndi wopanda mtundu kuti kuwala wachikasu mandala madzi ndi fungo pang'ono ammonia. Ndi miscible ndi madzi mu gawo lililonse ndi kusungunuka mu zosungunulira zosiyanasiyana organic monga etha, acetone ndi esters, halogenated hydrocarbons, Chemicalbook aromatics, etc., pafupifupi Sakanizani bwino ndi zosungunulira zonse. Ndiwokhazikika munjira yosalowerera ndale; imasungunuka pang'onopang'ono mu hydrochloric acid kuti ipange 4-methylaminobutyric acid.

Cholinga cha N-methylpyrrolidone (NMP) ndi polar aprotic solvent. Ili ndi kawopsedwe wochepa, malo otentha kwambiri komanso kusungunuka kwabwino kwambiri. Ubwino wa selectivity amphamvu ndi kukhazikika kwabwino. Amagwiritsidwa ntchito kwambiri muzonunkhira za hydrocarbon m'zigawo, kuyeretsa acetylene, olefins ndi dienes, zosungunulira za polyvinylidene fluoride, ma elekitirodi othandizira mabatire a lithiamu-ion, syngas desulfurization, kuyenga mafuta, kudzoza mafuta oletsa kuzizira, Chemicalbook olefin m'zigawo za polima. insoluble engineering mapulasitiki, herbicides ulimi, kutchinjiriza zipangizo, Integrated dera kupanga, kuyeretsa zida mwatsatanetsatane ndi matabwa dera mu semiconductor makampani, PVC utsi mpweya kuchira, kuyeretsa wothandizila, utoto zina, dispersants, etc. Amagwiritsidwanso ntchito ngati zosungunulira ma polima ndi sing'anga yopangira ma polymerization, monga mapulasitiki a engineering ndi ma aramid fibers. Kuphatikiza apo, itha kugwiritsidwanso ntchito mu mankhwala ophera tizilombo, mankhwala ndi zotsukira, etc.
