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

incazelo emfushane:

I-N-Methyl Pyrrolidone ibizwa ngokuthi i-NMP, ifomula yamangqamuzana: C5H9NO, isiNgisi: 1-Methyl-2-pyrrolidinone, ukubukeka awanambala kuya kuketshezi olukhanyayo oluphuzi olukhanyayo, iphunga elincane le-ammonia, elixubene namanzi nganoma iyiphi ingxenye, lincibilika ku-ether, i-acetone Kanye nezinyibilikisi ezihlukahlukene ze-organic, i-halogen, i-hydrocarbon, i-hydrocarbon ecishe ibe yi-aromatic. ixutshwe nazo zonke izincibilikisi, indawo yokubilisa engu-204 ℃, iphoyinti elikhanyayo 91 ℃, i-hygroscopicity eqinile, izakhiwo zamakhemikhali ezizinzile, ezingagqwali ku-carbon steel, i-aluminium, ithusi Igqwala kancane. I-NMP inezinzuzo ze-viscosity ephansi, ukuzinza okuhle kwamakhemikhali kanye nokuzinza kwe-thermal, i-polarity ephezulu, ukuguquguquka okuphansi, nokungezwani okungapheli kwamanzi kanye nezinyibilikisi eziningi eziphilayo. I-NMP iyisidakamizwa esincane, futhi umkhawulo ovumelekile wokugxila emoyeni ngu-100PPM.

Izicelo ze-NMP

I-N-methylpyrrolidone (NMP) iyi-solvent ye-polar aprotic. Inobuthi obuphansi, indawo yokubilisa ephezulu kanye nokuncibilika okuvelele. Izinzuzo zokukhetha okuqinile nokuzinza okuhle. Isetshenziswa kakhulu ekukhishweni kwe-hydrocarbon enamakha, ukuhlanzwa kwe-acetylene, i-olefin ne-diolefin, izinyibilikisi ze-polyvinylidene fluoride, izinto ezisizayo ze-electrode zamabhethri e-lithium ion, i-syngas desulfurization, ukucwenga uwoyela wokugcoba, ukugcoba uwoyela wokunqanda ukuqhwala, i-olefin ekhipha i-olefin ku-extractant yezolimo, i-polymerization yakhe yepulasitiki izinto zokwakha, ukukhiqizwa kwesekethe edidiyelwe, ukuhlanzwa kwezinsimbi ezinembile embonini ye-semiconductor, amabhodi wesifunda, i-PVC yokukhipha igesi yokubuyisela, ama-ejenti okuhlanza, ama-axiliaries odayi, ama-dispersants, njll. Ibuye isetshenziswe njenge-solvent yama-polymers kanye ne-medium for polymerization, njengepulasitiki yobunjiniyela nama-aramid fibers. Ingasetshenziswa nasezibulala-zinambuzane, imithi kanye nama-ejenti okuhlanza. Ukusetshenziswa okuyinhloko kwamabanga ahlukene we-N-methylpyrrolidone kubalwe ngezansi:

1. Ibanga lezimboni: ukucwenga uwoyela wokugcoba, ukugcotshwa kukawoyela wokuthambisa, i-syngas desulfurization, izinto zokufakelwa kwe-elekthronikhi, izibulala-zinambuzane zezolimo, izinsizi zezibulala-zinambuzane, i-PVC exhaust gas recovery, ama-auxiliaries kanye nama-disperants okukhiqizwa kwezingubo zezinga eliphezulu, oyinki, ombala bemibala, njll. ukucwenga uwoyela wokugcoba; ngenxa yokuncibilika okuphezulu kwe-NMP ku-resin, ingasetshenziswa njenge-solvent ye-resin kanye ne-Chemicalbook ezosetshenziswa ekwenzeni izimbotshana, amapende aphansi, ama-varnish, ama-composite coatings, ukwakhiwa kwefilimu, okudidiyelwe kwe-Circuit enameled wire insulation materials, izindwangu ze-fiber kanye ne-adhesives neminye imikhiqizo.

2. Ibanga elijwayelekile: ukukhishwa nokubuyiselwa kwezinto eziyisisekelo ze-organic, njengokugxilwa kwe-acetylene kanye nokukhishwa kwe-butadiene, isoprene, ama-hydrocarbons anuka kamnandi, njll. njenge-extractant yokuhlukanisa nokubuyisela i-high-purity butadiene kuma-hydrocarbon e-C4 aqhekekile, izinga lokubuyisela lingafinyelela ku-97%. %, ukuhlanzeka kwe-butadiene etholiwe kungu-99.7%, futhi isetshenziswa njenge-extractant yokuthola i-isoprene ephezulu ekuqhekekeni ama-hydrocarbon e-C5, futhi ukuhlanzeka kokululama kwe-isoprene kufinyelela ku-99%; uma isetshenziswa njenge-extractant yama-hydrocarbon anephunga elimnandi, inokuncibilika okuphezulu kuma-hydrocarbon anephunga elimnandi. Ngomfutho we-vapor ophansi, izinga lokulahlekelwa kwe-extractant liphansi futhi izinga lokutholwa kwama-aromatics liphezulu.

3. Ibanga le-Reagent: Ukunciphisa, ukwehlisa, ukukhishwa kwe-waxing, ukupholishwa, ukuvimbela ukugqwala, ukukhumula upende, njll. ezimbonini ezidinga ukulawulwa okuqinile kwama-ion ensimbi nama-microparticles kumasekethe ahlanganisiwe, ama-hard disks, njll. nezincibilikisi ezikhiqizwe embonini yezemithi njengolwelwesi lwe-membrane yokusebenza kwezinso zokwenziwa, uketshezi olukhipha usawoti emanzini olwandle, njll.
