Umenzi wexabiso eliLungileyo i-N-METHYL PYRROLIDONE (NMP) CAS: 872-50-4

inkcazelo emfutshane:

I-N-Methyl Pyrrolidone ibizwa ngokuba yi-NMP, i-molecular formula: C5H9NO, isiNgesi: 1-Methyl-2-pyrrolidinone, imbonakalo ayinambala ukuya kulwelo olukhanyayo olukhanyayo, ivumba le-ammonia kancinane, ixubene namanzi nakweyiphi na imilinganiselo, inyibilika kwi-ether, Iacetone Kunye nezinyibilikisi ezahlukeneyo zezinto eziphilayo ezifana nee-esters, ihalogenated hydrocarbons, iihydrocarbons ezinuka kamnandi, phantse zixutywe ngokupheleleyo nazo zonke izinyibilikisi, indawo ebilayo 204 ℃, i-flash point 91 ℃, i-hygroscopicity eqinile, iipropathi zekhemikhali ezizinzileyo, ezingadleki kwi-carbon steel, i-aluminiyam, ikopolo Kancinane. edlekayo.I-NMP ineenzuzo ze-viscosity ephantsi, uzinzo oluhle lweekhemikhali kunye nokuzinza kwe-thermal, i-polarity ephezulu, ukuguquguquka okuphantsi, kunye nokungahambi kakuhle kwamanzi kunye nezinyibiliki ezininzi zezinto eziphilayo.I-NMP yi-micro-drug, kwaye umda ovumelekileyo woxinaniso emoyeni yi-100PPM.

Usetyenziso lwe-NMP

I-N-methylpyrrolidone (NMP) sisinyibilikisi se-aprotic emhlophe.Inobuthi obuphantsi, indawo yokubilisa ephezulu kunye nokunyibilika okubalaseleyo.Iinzuzo zokukhetha okunamandla kunye nokuzinza okulungileyo.Isetyenziswa kakhulu kwi-extraction ye-hydrocarbon enevumba elimnandi, ukucocwa kwe-acetylene, i-olefin kunye ne-diolefins, izinyibilikisi ze-polyvinylidene fluoride, izixhobo ezincedisa i-electrode kwiibhetri ze-lithium ion, i-syngas desulfurization, ukucocwa kweoli yokuthambisa, ukuthambisa i-oyile yokuthambisa, i-olefin extractant kwi-polymerization yobunjineli beplastiki , i-herbicides yezolimo, i-insulating materials, imveliso yesekethe edibeneyo, ukucocwa kwezixhobo ezichanekileyo kwishishini le-semiconductor, iibhodi zeesekethe, i-PVC yokukhupha igesi yokubuyisela, i-agent yokucoca, i-dayi encedisayo, i-dispersants, njl. ukwenza i-polymerization, njengeeplastiki zobunjineli kunye ne-aramid fibers.Ingasetyenziswa nakwizitshabalalisi, amayeza kunye neearhente zokucoca.Usetyenziso oluphambili lwamabanga ahlukeneyo e-N-methylpyrrolidone zidweliswe ngezantsi:

1. Ibakala Industrial: ekuthambiseni ukucokisa ioli, ukuthambisa ioli antifreeze, i-syngas desulfurization, izinto zokugquma nge-elektroniki, imichiza yezolimo, izincedisi ze-pesticide, i-PVC exhaust gas recovery, ii-axiliaries kunye ne-dispersants zokuvelisa i-coatings yodidi oluphezulu, ii-inki, ii-pigments, njl. umzekelo, isetyenziselwa ukukhupha iihydrocarbons ezinevumba elimnandi kwi-oyile yokuthambisa ukuze kuphunyezwe injongo yokusulungekisa ioyile yokuthambisa;ngenxa yokunyibilika okuphezulu kwe-NMP kwi-resin, inokusetyenziswa njengesinyibilikisi se-resin kunye ne-Chemicalbook ukuba isetyenziswe ekwenzeni iingubo, iipeyinti zomgangatho, i-varnishes, i-composite coatings, ukwenza ifilimu, i-Circuit enameled wire insulation materials, ifayibha. amalaphu kunye nezinto ezincamathelayo kunye nezinye iimveliso.

2. Ibakala eliqhelekileyo: ukukhutshwa kunye nokubuyiswa kwezinto ezisisiseko zezinto eziphilayo, ezifana nokugxininiswa kwe-acetylene kunye nokukhutshwa kwe-butadiene, i-isoprene, i-hydrocarboni enevumba elimnandi, njl. kunye nokucoceka kokubuyisela i-acetylene egxininisiweyo inokufikelela kuma-99.7%;njenge-extractant yokwahlula kunye nokubuyisela ucoceko oluphezulu lwe-butadiene kwi-C4 hydrocarbons eqhekekileyo, izinga lokubuyisela lingafikelela kwi-97%.%, ukucoceka kwe-butadiene efunyenweyo yi-99.7%, kwaye isetyenziswe njenge-extractant yokubuyisela i-isoprene ephezulu yokuhlanjululwa kwe-C5 hydrocarbons, kunye nokuhlanjululwa kwe-isoprene kufinyelela kwi-99%;xa isetyenziselwa ukutsalwa kweehydrocarbons ezinevumba elimnandi, inokunyibilika okuphezulu kweehydrocarbons ezinuka kamnandi.Ngoxinzelelo oluphantsi lomphunga, izinga lokulahleka kwe-extractant liphantsi kwaye izinga lokubuyisela i-aromatics liphezulu.

3. Ibakala le-Reagent: Ukunciphisa, ukuchithwa, ukuchithwa, ukupholisa, ukuthintela ukugqwala, ukuchithwa kwepeyinti, njl. , iibhodi zesekethe eziprintiweyo zePCB, iihard disks;kunye nezinyibilikisi eziveliswe kwishishini loxubo-mayeza ezifana ne-factrificial kidney function membrane fluid, i-seawater desalination membrane fluid, njl.
