Intengo Enhle Yomkhiqizi I-N-METHYL PYRROLIDONE (NMP) CAS: 872-50-4 Isithombe Esifakiwe

incazelo emfushane:

I-N-Methyl Pyrrolidone ibizwa ngokuthi i-NMP, ifomula yama-molecule: C5H9NO, isiNgisi: 1-Methyl-2-pyrrolidinone, ukubukeka kwayo akunambala kuya koketshezi olukhanyayo oluphuzi, iphunga elincane le-ammonia, ixubana namanzi nganoma iyiphi indlela, incibilika ku-ether, i-acetone kanye nezinyibilikisi ezahlukahlukene eziphilayo ezifana nama-esters, ama-hydrocarbons e-halogenated, ama-hydrocarbons aromatic, cishe axutshwe ngokuphelele nazo zonke izinyibilikisi, iphuzu lokubilisa elingu-204 ℃, iphuzu le-flash elingu-91 ℃, i-hygroscopicity eqinile, izakhiwo zamakhemikhali ezizinzile, ezingaboliyo ensimbini yekhabhoni, i-aluminium, ithusi. Ibolisisa kancane. I-NMP inezinzuzo ze-viscosity ephansi, ukuzinza okuhle kwamakhemikhali kanye nokuzinza kokushisa, i-polarity ephezulu, ukuguquguquka okuphansi, kanye nokungafani okungenamkhawulo namanzi kanye nezinyibilikisi eziningi eziphilayo. I-NMP iyisidakamizwa esincane, futhi ukuhlushwa okulinganiselwe okuvunyelwe emoyeni kungu-100PPM.

Izicelo ze-NMP

I-N-methylpyrrolidone (NMP) iyi-solvent ye-polar aprotic. Inobuthi obuphansi, iphuzu lokubila eliphezulu kanye nokuncibilika okuvelele. Izinzuzo zokukhetha okuqinile kanye nokuqina okuhle. Isetshenziswa kabanzi ekukhishweni kwe-aromatic hydrocarbon, ukuhlanzwa kwe-acetylene, ama-olefin nama-diolefin, izinyibilikisi ze-polyvinylidene fluoride, izinto ezisizayo ze-electrode zamabhethri e-lithium ion, i-syngas desulfurization, ukuhluzwa kwamafutha okugcoba, i-lubricating oil antifreeze, i-olefin extractant, izinyibilikisi ezinzima ekupholimeni kwepulasitiki yobunjiniyela, ukubulala ukhula kwezolimo, izinto zokufaka umswakama, ukukhiqizwa kwesekethe ehlanganisiwe, ukuhlanzwa kwezinsimbi ezinembile embonini ye-semiconductor, amabhodi esekethe, ukubuyiselwa kwegesi yokukhipha i-PVC, izinto zokuhlanza, izithasiselo zodayi, izihlakaza, njll. Iphinde isetshenziswe njenge-solvent yama-polymer kanye nendawo yokwenza i-polymerization, njengepulasitiki yobunjiniyela kanye nemicu ye-aramid. Ingasetshenziswa futhi ezibulala-zinambuzane, emithini nasezintweni zokuhlanza. Ukusetshenziswa okuyinhloko kwamazinga ahlukene e-N-methylpyrrolidone kubalwe ngezansi:

1. Izinga lezimboni: ukuhluzwa kwamafutha okugcoba, ukuhluzwa kwamafutha okugcoba okulwa nokuqandisa, ukuhlanzwa kwe-syngas, izinto zokushisa zikagesi, ukubulala ukhula kwezolimo, izithasiselo zokubulala izinambuzane, ukubuyiswa kwegesi yokukhipha i-PVC, izithasiselo kanye nezisabalalisi zokukhiqiza izembozo zezinga eliphezulu, uyinki, imibala, njll. Isibonelo, isetshenziselwa ukukhipha ama-hydrocarbon aromatic kumafutha okugcoba ukuze kufezwe injongo yokuhluzwa kwamafutha okugcoba; ngenxa yokuncibilika okuphezulu kwe-NMP ku-resin, ingasetshenziswa njengesithasiselo se-resin kanye ne-Chemicalbook ukuze isetshenziswe ekwenziweni kwezimbozo, upende waphansi, ama-varnish, izembozo ezihlanganisiwe, ukwakha ifilimu, izinto zokushisa ze-Circuit enamel ezihlanganisiwe, izindwangu ze-fiber kanye nezinamathiselo neminye imikhiqizo.

2. Izinga elijwayelekile: ukukhishwa nokubuyiswa kwezinto eziyisisekelo zokusetshenziswa kwezinto eziphilayo, njengokuhlushwa kwe-acetylene nokukhishwa kwe-butadiene, i-isoprene, ama-hydrocarbon aromatic, njll. Ingasetshenziswa njengesithako sokubuyisa i-acetylene kusuka kugesi yemvelo noma igesi ekhanyayo yokuqhekeka kwe-naphtha, kanti ubumsulwa bokubuyisa i-acetylene egxilile bungafinyelela ku-99.7%; njengesithako sokuhlukanisa nokubuyisa i-butadiene ehlanzekile kakhulu kuma-hydrocarbon e-C4 aqhekekile, izinga lokubuyisa lingafinyelela ku-97%. %, ubumsulwa be-butadiene ebuyiselwe bungu-99.7%, futhi isetshenziswa njengesithako sokubuyisa i-isoprene ehlanzekile kakhulu kuma-hydrocarbon e-C5 aqhekekile, kanti ubumsulwa bokubuyisa i-isoprene bufinyelela ku-99%; uma isetshenziswa njengesithako sama-hydrocarbon aromatic, inokuncibilika okuphezulu kwama-hydrocarbon aromatic. Ngomfutho ophansi womusi, izinga lokulahlekelwa kwesithako liphansi kanti izinga lokubuyisa lama-aromatic liphezulu.

3. Izinga le-Reagent: Ukususa amafutha, ukususa amafutha, ukususa i-dewaxing, ukupholisha, ukuvimbela ukugqwala, ukususa upende, njll. ezimbonini ezidinga ukulawulwa okuqinile kwama-ion ensimbi nama-microparticle kumasekethe ahlanganisiwe, ama-hard disk, njll. Ukuhlanzwa kwezinsimbi ezinembile, izinto ze-LCD liquid crystal, amabhodi esekethe aphrintiwe e-PCB, ama-hard disk; kanye nezinyibilikisi ezikhiqizwa embonini yezemithi njengoketshezi lwe-membrane function yezinso yokwenziwa, uketshezi lwe-membrane desalination lwamanzi olwandle, njll.
