N-I-methyl pyrlolidone (NMP), ifomula ye-molecular: c5h9no, isiNgisi: 1-methyl-2-pyrlolidinone, awunalo umbala we-plyrol, i-anmor how, i-actone, i-hydrocarbon, i-aced, i-hydrocarbons kanye nezinye izinto eziphilayo Solvents, cishe wonke ama-solvents aqedela amakhemikhali ahlanganisiwe, abilayo iphuzu 204 ℃, I-Flash Point 91 ℃, i-hygmoscopic, ukuqina kwamakhemikhali, akukho ukugqwala ku-carbon yensimbi, i-aluminium, okuwohloka kancane kwithusi. Inezinzuzo zokubonakala okuphansi, ukuqina okuhle kwamakhemikhali kanye nokuqina okushisayo, ubumbano obukhulu, ukuguquguquka okuphansi, nokungenakuqhathaniswa namanzi amaningi ezinto eziphilayo. Lo mkhiqizo umuthi omnene, ukugxila okuvumelekile emoyeni kungu-100ppm.
Izakhiwo nokuqina:
1. Uketshezi olungenamibala, ukunambitheka kwe-ammonia, ubuthi obuphansi balo mkhiqizo. Kungancibilika ngamanzi, kuncibilike kakhulu ezinhlafunweni eziningi ze-organic ezifana ne-ether ne-acetone. Ingancibilikisa amakhompiyutha amaningi we-organic ne-inorganic, amagesi we-polar, amakhompiyutha we-polymer wemvelo nokwenziwa.
2. Izakhiwo zamakhemikhali: zizinzile ngesisombululo esingathathi hlangothi. Ngemuva kwamahora angama-8 ka-4% weSodium Hydroxide Solution, 50% ~ 70% we-hydrolysis yenzekile. IHydrolysis yenzeka ngokugxila futhi ikhiqiza i-4-meth aminocyl acid. Ngenxa yokusabela kwesisekelo se-Cymbal, kungakhiqiza i-ketone noma i-sulfurburn.
3. Ebukhona be-Alkaline Catalysts, inomphumela we-Olefin, futhi ukusabela okuhlelekile kwenzeka endaweni yesithathu. I-N-methylporide ibuthakathaka i-alkali futhi ingakhiqiza usawoti hydrochloride. Yakhe ihlanganiswe nosawoti wensimbi osindayo, njengokushisa nge-nickel Bromide kuya ku-150 ℃, ekhiqiza i-niBR2 (C5H9ON) 3, nephuzu elincibilikayo le-105 ℃.
Indlela yokukhiqiza:Itholakala ngokusabela kusuka ku-γ-butthochroditette kanye ne-methylemine. Isinyathelo sokuqala sokuphendula ukukhiqiza i-4-hydroxl-n-methyl-base-Amine ye-γ-butthlor kanye ne-methylide, futhi isinyathelo sesibili senziwe njolela ukukhiqiza i-n-methylypidoone. Ukusabela kwezinyathelo ezimbili kungenziwa ngomugqa ku-reactur reactor. I-γ-butthole ingu-1: 1.15, ingcindezi imayelana ne-6MPA, kanti izinga lokushisa lingu-250 ° C. Ngemuva kokuthi ukusabela sekuqediwe, umkhiqizo oqediwe utholakale ngokufakwa okuhlanganisiwe kanye nokucindezelwa. Izinga lemali engenayo lingama-90%. Uma kukhiqizwa i-kettle anti-chemicalbook, inani le-methylmine lingama-1.5-2,5 times izikhathi ngenani lethiyori, futhi ukulungiselela kwelebhu kusetshenziswa njengesibonelo. Phakathi kwama-hydropower angama-500ml, 2MOL γ-Butterwotone no-4 Moore Liquid zengezwa ukuthi kuvalwe futhi kufuthelwe kuvalwe ku-280 ° C. Ngemuva kokupholisa, khipha i-methamine ngokweqile, i-distillation, ukuqoqa amaphuzu we-distillation ka-201-202 Ukusetshenziswa okubonakalayo okungavuthiwe (kg / g) γ-butthoboretin 980 methyline (40%) 860.
Ukusebenza nesitoreji:
1. Indlela yokugcina
Gcina ngaphansi kwegesi esomile, gcina isitsha esivaliwe, bese sigcina endaweni epholile neyomile.
2. Ukusetshenziswa kokusebenza
Gwema Ukuvezwa: Udinga ukuthola ukuholwa okukhethekile ngaphambi kokusebenzisa. Gwema ukuxhumana nesikhumba namehlo. Gwema ukuphefumula komphunga kanye nentuthu. Ungasondeli emthonjeni womlilo. -Akubhenywa. Thatha izinyathelo ukuvikela ukunqwabelana okulo.
3. Izinyathelo zokugcina
Kunendawo epholile kwisitoreji. Gcina isitsha sivaliwe futhi sigcine endaweni eyomile futhi enomoya. Isitsha esivulekile kufanele sivalwe ngokucophelela futhi sigcine isikhundla mpo ukuvikela ukuvuza. Ukuqedwa kokulondolozwa okuvuthayo kuyazwela umswakama.
Ukupakishwa: 200kg / Drum
