N-I-METHYL PYRROLIDONE(NMP), ifomula yemolekyuli :C5H9NO, isiNgesi:1-Methyl-2-pyrrolidinone, ayinambala ukuya kulwelo olucacileyo olutyheli, ivumba leammonia kancinane, lixutywe namanzi nakweliphi na inqanaba, inyibilikiswa kwi-ethyl ether, iacetone, i-ester, ihalogenated hydrocarbon, iihydrocarbons ezinuka kamnandi kunye nezinye izinto eziphilayo. i-solvents, Phantse zonke izinyibilikisi zigqiba umxube we-Chemicalbook, indawo ebilayo i-204 ℃, i-flash point 91℃, i-hygmoscopic, ukuzinza kweekhemikhali, akukho mhlwa kwi-carbon steel, i-aluminiyam, i-corrosive kancinane kubhedu.Ineenzuzo ze-viscosity ephantsi, ukuzinza okuhle kweekhemikhali kunye nokuzinza kwe-thermal, i-polarity ephezulu, i-volatility ephantsi, kunye nokungahambi kakuhle okungapheliyo ngamanzi kunye ne-solvents ezininzi zezinto eziphilayo.Le mveliso iyisiyobisi esincinci, umda ovumelekileyo wokugxininiswa emoyeni ngu-100PPM.
Iipropati kunye nozinzo:
1. Ulwelo olungenambala, incasa ye-ammonia, ubuthi obuphantsi bale mveliso.Inokunyibilika ngamanzi, inyibilika kuninzi lwezinyibilikisi eziphilayo ezifana ne-ether kunye ne-acetone.Iyakwazi ukunyibilikisa i-organic and inorganic compounds, ii-polar gases, zendalo kunye ne-synthetic polymer compounds.
2. Iimpawu zeMichiza: uzinzile kwisisombululo esingathathi hlangothi.Emva kweeyure ezi-8 ze-4% yesisombululo se-sodium hydroxide, i-50% ~ 70% ye-hydrolysis yenzeke.I-Hydrolysis yenzeka kwi-concentrates kwaye ivelise i-4-meth aminocyl acid.Ngenxa yokusabela kwesiseko se-cymbal, inokuvelisa i-ketone okanye i-sulfurboline.
3. Kubukho be-alkaline catalysts, inomphumela we-olefin, kwaye i-alkylated reaction yenzeke kwindawo yesithathu.I-N-methylporide i-alkaline ebuthathaka kwaye inokuvelisa i-salty hydrochloride.Yenze idityaniswe netyuwa yentsimbi enzima, njengokufudumeza nge-nickel bromide ukuya kwi-150℃, ivelisa i-NIBR2(C5H9ON)3, kunye nendawo yokunyibilika ye-105℃.
Indlela yokuvelisa:Ifunyenwe ngokusabela kwi-γ-butthochrodittes kunye ne-methylemine.Isinyathelo sokuqala sokuphendula kukuvelisa i-4-hydroxyl-N-methyl-base amine ye-γ-butthlor kunye ne-methylide, kwaye inyathelo lesibini lihlanjululwa ukuze livelise i-N-methylpidohone.Ukusabela kwamanyathelo amabini kunokwenziwa ngokulandelelana kwi-reactor tube.I-γ-butthole yi-1: 1.15, uxinzelelo malunga ne-6MPa, kwaye iqondo lokushisa li-250 ° C. Emva kokuphendula kugqityiwe, imveliso egqityiweyo ifunyenwe ngokugxilwa kunye ne-decompression distillation.Ingeniso yi-90%.Ukuba i-kettle anti-ChemicalBook iveliswa, inani le-methylmine liyi-1.5-2.5 amaxesha eethiyori, kwaye ukulungiswa kwebhubhoratri kusetyenziswa njengomzekelo.Phakathi kwe-500ml hydropower, i-2mol γ-buttertone kunye ne-4 Moore liquid zongezwa ukuba zivaliwe kwaye zifudunyezwe zivaliwe kwi-280 ° C nge-4h.Emva kokupholisa, khulula i-methamine eninzi, i-distillation, iqokelele amanqaku angama-201-202 ° C, ufumane malunga ne-180g yeemveliso, kwaye ingeniso iya kuba malunga ne-90%.Ukusetyenziswa kwezinto eziluhlaza (kg / g) γ-butthoboretin 980 methyline (40%) 860.
Ukusebenza kunye nokugcinwa:
1. Indlela yokugcina
Gcina phantsi kwegesi eyomileyo ye-inert, gcina i-container ivaliwe, kwaye uyigcine kwindawo epholileyo neyomileyo.
2. Izilumkiso zokusebenza
Kuphephe ukuvezwa: Kufuneka ufumane isikhokelo esikhethekileyo phambi kokusetyenziswa.Kuphephe ukudibana nolusu namehlo.Kuphephe ukuphefumla umphunga kunye nomsi.Ungasondeli kumthombo womlilo.-Akutshaywa.Thatha amanyathelo okuthintela ukuqokelelana okumileyo.
3. Izilumkiso zokugcina
Kukho indawo epholileyo yokugcina.Gcina isikhongozeli sivaliwe kwaye usigcine kwindawo eyomileyo nengena umoya.Isikhongozeli esivulekileyo kufuneka sivalwe ngononophelo kwaye sigcine ukuma nkqo ukuthintela ukuvuza.Ukuphelisa ukugcinwa kwe-inflatable kunovakalelo kumswakama.
