Ibisobanuro
N-Methyl-2-pyrrolidone ni umuti ukozwe mu buryo bwa aprotic ufite akamaro kanini: gutunganya peteroli, gusiga irangi ku buso, irangi n'ibindi bikoresho, isuku y'inganda n'iy'iwabo, hamwe n'imiti ikoreshwa mu buhinzi n'imiti. Ni umuti utera ububabare, ariko kandi wateje indwara nyinshi zo mu bwoko bwa contact dermatitis mu kigo gito cy'ikoranabuhanga.

N-Methyl-2-pyrrolidone (NMP) ni solvent yo mu bwoko bwa polar aprotic ifite ibyiza byo kuba uburozi buke, ubushyuhe bwinshi, ubushobozi bwo gushonga neza, guhitamo neza no kudahungabana.
Ikoreshwa cyane mu gusukura imyuka ihumura neza ya hydrocarbon, acetylene, olefini, na diolefini.
Ikoreshwa mu gusukura inganda, kandi ikora nk'umusemburo mu gukora imiti yica udukoko, pulasitiki y'ubuhanga, irangi, insinga z'ubukorikori, n'imiyoboro ivanze.
Ishobora kandi gukoreshwa nk'umuti wo gusukura, gusukamo irangi, irangi, amavuta yo kwisiga no kurwanya gukonjesha.
N-Methyl-2-pyrrolidone ni umuti mwiza cyane, ukoreshwa cyane mu gukuramo aromatike, gutunganya amavuta, kongera acetylene, gutandukanya butadiene no gukuramo gaze mu buryo bwa synthesis.
Ikoreshwa mu gusohora gazi, gusiga amavuta, gusiga amavuta arwanya gukonjesha, gukuramo olefin, no nk'ikintu gishongesha polimeri ya pulasitiki idashobora gushonga.
Ishobora gukoreshwa mu gusukura ibikoresho byo gukingira, ibikoresho byo mu nganda za semiconductor n'amadirishya, kongera gukoresha imyuka ya PVC, nk'isabune, inyunganiramirire n'umuti ukwirakwiza irangi.
Ikoreshwa mu buryo bwo gukora polimeri nk'imashini zikora pulasitiki n'imashini zikora diyabete za aramide.
N-Methyl-2-pyrrolidone ikoreshwa nk'umusemburo wa polyvinylidene fluoride n'ibikoresho by'inyongera bya electrode kuri bateri za lithium ion.
urwego rwo hejuru rw'ubuziranenge bwo gupima ICP-MS.
Ku bijyanye no gukora peptide.
Gupakira no Kohereza
25KG/Ingoma cyangwa nk'uko umukiriya abikeneye.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
