Ixabiso Elihle Lomenzi I-N-METHYL PYRROLIDONE (NMP) CAS: 872-50-4 Umfanekiso Obonakalayo

inkcazo emfutshane:

I-N-Methyl Pyrrolidone ibizwa ngokuba yi-NMP, ifomula yemolekyuli: C5H9NO, isiNgesi: 1-Methyl-2-pyrrolidinone, imbonakalo yayo ayinambala ukuya koluphuzi olukhanyayo, ivumba elincinci le-ammonia, ixutywa namanzi nangayiphi na indlela, iyanyibilika kwi-ether, i-acetone kunye nezinye izinyibilikisi zendalo ezifana nee-esters, ii-hydrocarbons ze-halogenated, ii-hydrocarbons ezinuka kamnandi, zixutywe phantse ngokupheleleyo nazo zonke izinyibilikisi, iqondo lokubila liyi-204 ℃, i-flash point 91 ℃, i-hygroscopicity enamandla, iipropati zeekhemikhali ezizinzileyo, i-non-corrosive kwi-carbon steel, i-aluminium, i-copper I-corrosive kancinci. I-NMP ineenzuzo ze-viscosity ephantsi, uzinzo oluhle lweekhemikhali kunye nokuzinza kobushushu, i-polarity ephezulu, i-volatility ephantsi, kunye nokungafani okungenamkhawulo namanzi kunye nezinyibilikisi ezininzi zendalo. I-NMP sisiyobisi esincinci, kwaye uxinano oluvumelekileyo emoyeni yi-100PPM.

Izicelo ze-NMP

I-N-methylpyrrolidone (NMP) sisinyibilikisi se-polar aprotic. Sinobuthi obuphantsi, indawo yokubila ephezulu kunye nokunyibilika okugqwesileyo. Iingenelo zokukhetha okunamandla kunye nokuzinza okuhle. Isetyenziswa kakhulu ekukhupheni i-aromatic hydrocarbon, ukucocwa kwe-acetylene, ii-olefins kunye nee-diolefins, izinyibilikisi ze-polyvinylidene fluoride, izixhobo ezincedisayo ze-electrode kwiibhetri ze-lithium ion, i-syngas desulfurization, ukucocwa kweoyile yokuthambisa, i-oyile yokuthambisa i-antifreeze, i-olefin extractant, i-solvents enzima kwi-polymerization yeplastiki yobunjineli, i-herbicides yezolimo, izixhobo zokukhusela, imveliso yesekethe edibeneyo, ukucocwa kwezixhobo ezichanekileyo kushishino lwe-semiconductor, iibhodi zesekethe, ukubuyiswa kwegesi yokukhupha i-PVC, ii-agents zokucoca, ii-dye auxiliaries, ii-dispersants, njl. Ikwasetyenziswa njengesinyibilikisi seepolymers kunye nendawo yokwenza i-polymerization, njengeeplastiki zobunjineli kunye neefayibha ze-aramid. Ingasetyenziswa nakwizibulali-zinambuzane, amayeza kunye neearhente zokucoca. Ukusetyenziswa okuphambili kwamanqanaba ahlukeneyo e-N-methylpyrrolidone kudweliswe ngezantsi:

1. Udidi lwemizi-mveliso: ukucocwa kweoyile yokuthambisa, ukuthambisa ioyile yokuthambisa, ukunyibilikisa i-syngas, izixhobo zokufakelwa kwe-elektroniki, izibulali-zinambuzane zezolimo, izincedisi zezinambuzane, ukubuyiswa kwegesi yokukhupha i-PVC, izincedisi kunye nezisasazi zokuvelisa iingubo eziphezulu, ii-inki, imibala, njl. Umzekelo, isetyenziselwa ukukhupha ii-hydrocarbons ezinuka kamnandi kwioyile yokuthambisa ukufezekisa injongo yokucoca ioyile yokuthambisa; ngenxa yokunyibilika okuphezulu kwe-NMP kwi-resin, ingasetyenziswa njengesinyibilikisi se-resin kunye neChemicalbook ukuze isetyenziswe ekwenzeni iingubo, iipeyinti zomgangatho, ii-varnish, iingubo ezidityanisiweyo, ukwenza ifilimu, izixhobo zokufakelwa kwe-Circuit enamel, amalaphu efayibha kunye nezincamathelisi kunye nezinye iimveliso.

2. Udidi oluqhelekileyo: ukukhupha nokubuyisela izinto ezisisiseko zendalo, ezifana noxinzelelo lwe-acetylene kunye nokukhupha i-butadiene, i-isoprene, ii-hydrocarbons ezinuka kamnandi, njl. Ingasetyenziswa njengesinyibilikisi sokubuyisela i-acetylene kwigesi yendalo okanye igesi yokuqhekeka kobushushu ye-naphtha ekhaphukhaphu, kwaye ubumsulwa bokubuyisela i-acetylene exineneyo bunokufikelela kwi-99.7%; njenge-extractant yokwahlula nokubuyisela i-butadiene ecocekileyo kakhulu kwi-C4 hydrocarbons eziqhekekileyo, izinga lokubuyisela linokufikelela kwi-97% %, ubumsulwa be-butadiene efunyenweyo yi-99.7%, kwaye isetyenziswa njenge-extractant yokubuyisela i-isoprene ecocekileyo kakhulu kwi-C5 hydrocarbons eziqhekekileyo, kwaye ubumsulwa bokubuyisela i-isoprene bufikelela kwi-99%; xa isetyenziswa njenge-extractant yee-aromatic hydrocarbons, inokunyibilika okuphezulu kwee-aromatic hydrocarbons. Ngoxinzelelo oluphantsi lomphunga, izinga lokulahleka kwe-extractant liphantsi kwaye izinga lokubuyisela le-aromatics liphezulu.

3. Uhlobo lwe-Reagent: Ukususa amafutha, ukususa amafutha, ukususa ityuwa, ukupolisha, ukuthintela umhlwa, ukususa ipeyinti, njl.njl. kumashishini afuna ulawulo olungqongqo lwee-ion zesinyithi kunye nee-microparticles kwiisekethe ezidibeneyo, ii-hard disk, njl.njl. Ukucocwa kwezixhobo ezichanekileyo, izinto ze-LCD liquid crystal, iibhodi zesekethe eziprintiweyo ze-PCB, ii-hard disk; kunye nezinyibilikisi eziveliswa kushishino lwamayeza ezifana nolwelo lwe-membrane olusebenzayo lwezintso, ulwelo lwe-membrane olukhutshwa emanzini olwandle, njl.njl.
