Iimpawu zeMichiza

Ulwelo olunamafutha angenambala olungenambala olunevumba elincinane le-amine.Iyakwazi ukunyibilika ngamanzi, utywala, i-ether, i-ester, i-ketone, i-halogenated hydrocarbon, i-hydrocarbon enuka kamnandi.

amagqabantshintshi

I-N-methyl pyrrolidinone imfutshane, ifomula yeemolekyuli: C5H9NO, IsiNgesi: 1-methyl-2-PyrrolidinOne, imbonakalo ayinambala ukuya kulwelo olukhanyayo olutyheli olucacileyo, kunye nevumba elincinane le-ammonia, eliphosakele ngamanzi nakweyiphi na imilinganiselo, i-ether, i-acetone kunye ne-ether. i-ester, i-halogenated hydrocarbon, i-hydrocarbon enevumba elimnandi kunye nezinye izinyibilikisi eziphilayo, Phantse zixutywe ngokupheleleyo nazo zonke izinyibilikisi I-Chemicalbook, indawo ebilayo 204℃, i-flash point 91℃, i-hygroscopic, iipropati zekhemikhali ezizinzileyo, akukho mhlwa kwintsimbi ye-carbon, i-aluminiyam, i-corrosion kancinane kubhedu.Ineenzuzo ze-viscosity ephantsi, ikhemikhali elungileyo kunye nokuzinza kwe-thermal, i-polarity ephezulu, i-volatility ephantsi, i-miscibility engapheliyo ngamanzi kunye ne-solvents ezininzi zezinto eziphilayo, njl.

Usetyenziso oluphambili

(1.) Ibakala loshishino:
Ukucocwa kweoyile yokuthambisa, ukuthambisa i-oyile ye-antifreeze agent, i-syngas desulfurization, imathiriyeli yokugquma nge-elektroniki, imichiza yokutshabalalisa ukhula kwezolimo, izongezo ze-pesticide, i-PVC yokubuyisela irhasi yomsila, i-coatings yodidi oluphezulu, i-inki, imveliso ye-pigment yezongezo kunye ne-dispersants.Umzekelo, isetyenziselwa ukukhupha i-aromatics kwi-oyile yokuthambisa ukufezekisa injongo yokucoca i-oyile yokuthambisa;Ngenxa yokunyibilika okukhulu kweresin ye-NMP, njengesinyibilikisi sokulungiswa kwe-resin sinokusetyenziswa ngokuthe ngqo ekwenziweni kweengubo, ipeyinti yomgangatho, ivanishi, ifilimu edityanisiweyo yokugquma, isekethe edityanisiweyo yezixhobo zokugquma ucingo, amalaphu efayibha kunye nokuncamathelisa kunye nezinye iimveliso.

(2. )Inqanaba eliQhelekileyo:
Ukukhutshwa kunye nokubuyiselwa kwezinto ezisisiseko zezinto eziphilayo, ezifana ne-acetylene extraction kunye ne-butadiene, i-isoprene, i-aromatics kunye nezinye i-extraction.Ingasetyenziselwa njenge-solvent ukubuyisela i-acetylene kwigesi yendalo okanye igesi ekhanyayo ye-naphtha pyrolysis.Njenge-extractant yokwahlula kunye nokubuyiselwa kwe-high-purity butadiene ekuqhekekeni kwe-C4 hydrocarbon, izinga lokubuyisela liyi-97%, kunye nokuhlanjululwa kwe-butadiene efunyenweyo yi-99.7%.Njenge-extractant yokubuyisela ukucoceka okuphezulu kwe-isoprene ekuqhekekeni kwe-C5 hydrocarbon, ukucoceka kokubuyisela kwe-isoprene yi-99%.Ngenxa yokunyibilika kwayo okuphezulu kunye noxinzelelo oluphantsi lomphunga kwi-aromatics, inqanaba lelahleko yearhente yokutsalwa lisezantsi kwaye inqanaba lokubuyisela iaromatics liphezulu.

(3.) Inqanaba le-Reagent:
Isekethe edibeneyo, idisk enzima kunye nezinye iimfuno zolawulo olungqongqo lwee-ion zetsimbi kunye namasuntswana oshishino lwe-deoiling, degreasing, dewaxing, polishing, rust prevention, paint, such as photoresist remove liquid, IC semiconductor industry precision instruments, LCD liquid crystal materials, PCB ibhodi yesekethe eprintiweyo, hard disk ukucoca;Kunye nolwelo olwenziweyo lwenwebu lwezintso olusebenzayo, ulwelo lwe-membrane yokucoca amanzi olwandle kunye nezinye izinyibilikisi eziveliswe kushishino lwamayeza.
