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 olutyheli olucacileyo, ivumba elincinci le-ammonia, lixubene namanzi nakweyiphi na imilinganiselo, inyibilika kwi-ether, i-acetone kunye neentlobo ezahlukeneyo ze-organic solvents, i-halogen carbon, i-halogen, i-eridrojeni, i-halogen ixutywe nazo zonke izinyibilikisi, indawo ebilayo engu-204 ℃, i-flash point 91 ℃, i-hygroscopicity eyomeleleyo, iipropathi zekhemikhali ezizinzileyo, ezingadleliyo kwintsimbi ye-carbon, i-aluminiyam, ubhedu I-corrosive kancinane. 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 kwi-extractant yezolimo, i-polymerization ye-polymerization yezolimo izinto, imveliso yesekethe edibeneyo, ukucocwa kwezixhobo ezichanekileyo kwishishini le-semiconductor, iibhodi zesekethe, i-PVC yokukhupha igesi yokubuyisela, i-agent yokucoca, i-dayi encedisayo, i-dispersants, njl. Ingasetyenziswa nakwizitshabalalisi, amayeza kunye neearhente zokucoca. Usetyenziso oluphambili lwamabanga ahlukeneyo e-N-methylpyrrolidone zidweliswe ngezantsi:

1. Ibakala Industrial: ukucokisa ioli yokuthambisa, yokuthambisa ioli antifreeze, syngas desulfurization, izinto zokugquma ngombane, ukhula lwezolimo, abancedisi zinambuzane, PVC exhaust gas recovery, abancedisi kunye dispersants kwimveliso yodidi oluphezulu yokwambathisa, ii-inks, pigments, njl Umzekelo, isetyenziselwa injongo ye-oyile ye-lubricating ukuphumeza i-oyile ye-oyile ye-oyile esetyenziselwa ukuphumeza i-oyile ye-oyile. ukucokisa ioli yokuthambisa; ngenxa yokunyibilika okuphezulu kwe-NMP kwi-resin, ingasetyenziselwa njenge-solvent ye-resin kunye ne-Chemicalbook ukuba isetyenziswe ekwenzeni iingubo, iipeyinti zomgangatho, i-varnishes, i-composite coatings, i-film-forming, i-integrated Circuit enameled wire insulation materials, amalaphu efayibha kunye ne-adhesives kunye nezinye iimveliso.

2. Ibakala eliqhelekileyo: ukutsalwa kunye nokubuyiselwa kwezinto ezisisiseko zezinto eziphilayo, ezifana nokugxininiswa kwe-acetylene kunye nokutsalwa kwe-butadiene, isoprene, i-hydrocarbons enevumba elimnandi, njl njl. 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. kunye nezinyibilikisi eziveliswe kwishishini loxubo-mayeza ezifana ne-factrificial kidney function membrane fluid, i-seawater desalination membrane fluid, njl.
