N-I-METHYL PYRROLIDONE(NMP), ifomula yamangqamuzana :C5H9NO, isiNgisi:1-Methyl-2-pyrrolidinone, uketshezi olusobala olungenambala ukuya kokuphuzi, iphunga elincane le-ammonia, luxubene namanzi nganoma iyiphi ingxenye, luncibilikiswe ku-ethyl ether, i-acetone, i-ester, i-halogenated hydrocarbon, ama-hydrocarbon anephunga elimnandi nezinye izinto eziphilayo izincibilikisi, Cishe zonke izincibilikisi ziqedela ingxube ye-Chemicalbook, iphoyinti elibilayo elingu-204℃, iphoyinti elikhanyayo elingu-91℃, i-hygmoscopic, ukuqina kwamakhemikhali, akukho ukugqwala kunsimbi ye-carbon, i-aluminium, yonakalisa kancane ithusi.Inezinzuzo ze-viscosity ephansi, ukuzinza okuhle kwamakhemikhali kanye nokuzinza kokushisa, i-polarity ephezulu, i-volatility ephansi, nokungezwani okungapheli kwamanzi kanye nezinyibilikisi eziningi eziphilayo.Lo mkhiqizo umuthi omnene, umkhawulo ovunyelwe ukugxila emoyeni ngu-100PPM.
Izakhiwo nokuzinza:
1. Uketshezi olungenambala, ukunambitheka kwe-ammonia, ubuthi obuphansi balo mkhiqizo.Ingancibilika emanzini, inyibilike kuzincibilikisi eziningi eziphilayo njenge-ether ne-acetone.Ingancibilikisa izinhlanganisela eziningi ze-organic kanye ne-inorganic, amagesi e-polar, izinhlanganisela ze-polymer zemvelo nezokwenziwa.
2. Izakhiwo zamakhemikhali: azinzile kusixazululo esingathathi hlangothi.Ngemuva kwamahora angu-8 wesisombululo se-sodium hydroxide esingu-4%, u-50% ~ 70% we-hydrolysis wenzeka.I-Hydrolysis yenzeka ekugxiliseni futhi ikhiqize i-4-meth aminocyl acid.Ngenxa yokusabela kwesisekelo se-cymbal, ingakhiqiza i-ketone noma i-sulfurboline.
3. Ebukhoneni be-alkaline catalysts, inomphumela we-olefin, futhi ukusabela kwe-alkylated kwenzeka endaweni yesithathu.I-N-methylporide ine-alkaline ebuthakathaka futhi ingakhiqiza i-hydrochloride kasawoti.Yakha usawoti wensimbi osindayo odidiyelwe, njengokushisisa nge-nickel bromide ukuya ku-150℃, ikhiqiza i-NIBR2(C5H9ON)3, nendawo encibilikayo engu-105℃.
Indlela yokukhiqiza:Itholakala ngokusabela okuvela ku-γ-butthochroditettes kanye ne-methylemine.Isinyathelo sokuqala sokusabela ukukhiqiza i-4-hydroxyl-N-methyl-base amine ye-γ-butthlor ne-methylide, bese isinyathelo sesibili siphelelwa amanzi ukuze sikhiqize i-N-methylpidohone.Ukusabela kwezinyathelo ezimbili kungenziwa ngokulandelana ku-reactor yeshubhu.I-γ-butthole ingu-1: 1.15, ingcindezi imayelana ne-6MPa, futhi izinga lokushisa liyi-250 ° C. Ngemva kokuphendula kuqediwe, umkhiqizo oqediwe utholakala ngokugxila kanye ne-decompression distillation.Izinga lemali engenayo lingama-90%.Uma iketela le-anti-ChemicalBook likhiqizwa, inani le-methylmine liphindwe izikhathi ezingu-1.5-2.5 kunani lethiyori, futhi ukulungiswa kwelabhorethri kusetshenziswa njengesibonelo.Phakathi kuka-500ml hydropower, i-2mol γ-butterone kanye noketshezi lwe-Moore olu-4 kwengezwa ukuze kuvalwe futhi kushisiswe kuvalwe ku-280 ° C amahora angu-4.Ngemuva kokupholisa, khulula i-methamine eningi, i-distillation, uqoqe amaphuzu angu-201-202 ° C, uthole cishe u-180g wemikhiqizo, futhi imali engenayo izoba ngu-90%.Ukusetshenziswa kwempahla eluhlaza (kg/g) γ-butthoboretin 980 methyline (40%) 860.
Ukusebenza nokugcinwa:
1. Indlela yokugcina
Gcina ngaphansi kwegesi eyomile ye-inert, gcina isitsha sivaliwe, futhi ugcine endaweni epholile neyomile.
2. Izinyathelo zokuphepha zokusebenza
Gwema ukuchayeka: Udinga ukuthola ukuqondiswa okukhethekile ngaphambi kokusebenzisa.Gwema ukuthinta isikhumba namehlo.Gwema ukuhogela umhwamuko nentuthu.Ungasondeli umthombo womlilo.-Akubhenywa.Thatha izinyathelo zokuvimbela ukunqwabelana okumile.
3. Izinyathelo zokugcina
Kukhona indawo epholile yokugcina.Gcina isitsha sivaliwe futhi ugcine endaweni eyomile futhi engenawo umoya.Isiqukathi esivuliwe kufanele sivalwe ngokucophelela futhi sigcine ukuma okume mpo ukuvikela ukuvuza.Ukuqedwa kokulondolozwa kwe-inflatable kuzwela kumswakama.
