Iyini i-N-Methylpyrrolidone?
I-N-Methylpyrrolidone (NMP) iyinhlanganisela yemvelo ehlanganisa i-lactam enamalungu angu-5.Iwuketshezi olungenambala, nakuba amasampula angcolile angavela aphuzi.Ixubene namanzi kanye nezincibilikisi eziphilayo ezivame kakhulu.I-N-Methylpyrrolidone (NMP) iyi-solvent enhle kakhulu, esetshenziswa kabanzi ekwakhiweni, uphethiloli, imithi, imikhiqizo yamakhemikhali, amabhethri e-lithium neminye imikhakha.
Embonini yezemithi, i-N-Methylpyrrolidone (NMP) isetshenziswa ekwakhiweni kwezidakamizwa ngazo zombili izindlela zokuletha ngomlomo nange-transdermal, ikakhulukazi ezisetshenziswa kwezokwelapha, izidakamizwa zezilwane, abaphakathi kwezemithi.
Emkhakheni wezimboni, i-N-Methylpyrrolidone (NMP) ingasetshenziswa ekugxilweni kwe-acetylene, ukukhishwa kwe-butadiene, izinto zokufaka ugesi kagesi, ukugqoka okuphezulu, izithasiselo ze-pesticide, inki, i-pigment, i-ejenti yokuhlanza izimboni nezinye izimboni.I-NMP iphinde isetshenziswe kakhulu ekwenzeni ibhethri ye-lithium ion, njengesixazululi sokulungiselela i-electrode.Amabhethri e-lithium-ion asetshenziswa kakhulu emikhiqizweni ye-elekthronikhi ephathekayo, njengamakhompyutha aphathekayo, omakhalekhukhwini namakhamera edijithali.
Ibuye isetshenziswe njenge-solvent ekulungiseleleni ukuhweba kwe-polyphenylene sulfide.Isebenzisa imvelo yayo engaguquki kanye nekhono lokuncibilikisa izinto ezahlukahlukene, i-N-Methylpyrrolidone (NMP) ingasetshenziswa futhi ezimbonini ze-petrochemical kanye nepulasitiki njenge-solvent.
Ngamafuphi nje, i-N-Methylpyrrolidone (NMP) ibe yinto ebalulekile yamakhemikhali eluhlaza futhi eyenza iminikelo ebalulekile ezimbonini ezihlukahlukene.
Ikhiqizwa kanjani i-N-Methylpyrrolidone?
Kunezindlela ezimbalwa ezingasetshenziswa ukukhiqiza i-N-Methylpyrrolidone (NMP).Indlela eyodwa evamile yokukhiqiza i-NMP ihilela ukwelapha i-γ-butyrolactone(GBL) nge-methylamine, engaphansi kokushisa okuphezulu nokucindezela okukhulu.Lokhu kusabela kuvame ukuxutshwa ku-tube mixer kanye ne-γ-butyrolactone(GBL) ingakhiqizwa nge-dehydrogenated ye-1,4-Butanediol (BDO).Enye indlela ihlanganisa i-hydrogenation eyingxenye ye-N-methylsuccinimide kanye nokusabela kwe-acrylonitrile nge-methylamine elandelwa yi-hydrolysis.
Enye indlela yokukhiqiza i-N-Methylpyrrolidone (NMP) yindlela ye-pyrrolidone esekelwe ku-pyrrolidone nama-haloalkanes njengezinto zokusetshenziswa.
