Yintoni i-N-Methyl Pylolidone (NMP)?

N-I-Methyl Pylolidone (NMP), Ifomula yemolekyula: C5h9no, isiNgesi: I-Methyl-2-Pyralidinone, i-Acemor etyheli, i-Acemor, i-Acedic Hydrocarbon, i-hddrocarbon kunye nezinye izinto eziphilayo Izinyibilikisi, phantse zonke ii-slints zigqibe ukuxuba kwekhemikhali yekhemikhali, Inqaku lokubilisa 204 ℃, i-Flash Point 91 ℃, i-hygbmoscopic, uzinzo lwekhemikhali, akukho lutho kwi-carbon yentsimbi, ialuminiyam, i-corerosive yobhedu. Inezibonelelo zokubonisa okuphantsi, uzinzo lweekhemikhali ezifanelekileyo kunye nozinzo oluphakamileyo, eziphakamileyo, eziphantsi, kwaye zingenasiphoso ngamanzi kunye nezinyibilikisi ezininzi. Le mveliso ichiza elithambileyo, umda ovumelekileyo emoyeni yi-100PPPM.

Iipropathi kunye nozinzo:

I-1. Ulwelo olungenamibala, i-Amonia flavour, ityhefu esezantsi yale mveliso. Inganyibilika ngamanzi, inyibilikiswa kwiinyibiliki ezifana ne-organic ezifana ne-ether kunye ne-acetone. Ingayinyibilikisa i-ofisi ye-organic kunye negesi, igesi yePolar, yeNdalo neyokuphumeza i-polymer polymer.

2. Iipropathi zemichiza: Izinzile kwisisombululo ngokungathathi hlangothi. Emva kweeyure eziyi-8 ze-4% yesonacom ye-sodium hydroxide, i-50% ~ 70% ye-hydrolysis yenzekile. I-Hydrolysis ivela ekugxininiseni kwaye kuvelisa i-4-i-meth aminocyl acid. Ngenxa yokusabela kwesiseko seCymbal, kunokuvelisa i-ketoloy okanye i-sulfurbline.

3. Xa kukho ubukho be-Alkaline Catalysts, inefuthe le-olefin, kwaye indlela ye-alkylated yenzeka kwindawo yesithathu. I-N-Methylporide ibuthathaka i-alkaline kwaye inokuvelisa i-hydrochloride yetyuwa. Yenza ityuwa edityanisiweyo yetyuwa yentsimbi, njengokufudumeza nge-Nickel Bromide ukuya kwi-150 ℃, i-Nibr2 (C5H9on) 3, kunye nendawo yokunyibilika kwe-105 ℃.

Indlela yemveliso:Ifunyanwa ngempendulo evela kwi-γ-butthochroditte kunye ne-methylemine. Inyathelo lokuqala lokuphendula kukuvelisa i-4-i-bine ye-wine-i-bine ye-γ-bine ye-γ-bine ye-γ-bine ye-γ-bine kunye ne-methylide, kwaye inyathelo lesibini likhutshiwe ukuba livelise i-N-Methylpidohone. Impendulo yamanyathelo amabini inokwenziwa ngokulandelelana kwi-cube reactor. I-γ-butthole liyi-1: 1.15, uxinzelelo lumalunga ne-6MPA, kwaye iqondo lobushushu lingama-250 ° C. Emva kokuphendula kugqityiwe, imveliso egqityiweyo ifunyanwa yindawo yokuziphatha egqityiweyo kunye ne-decompiki. Ixabiso lengeniso ngama-90%. Ukuba i-KETTE Anti-Anti-Comilbow ivelisiwe, inani le-methylmine yi-1.5-2.5 AMANQAKU EZIQHELEKILEYO, kunye nokulungiselela kwelebhu kusetyenziswa njengomzekelo. Phakathi kwe-hydropower, 2mol γ-bhutrotone kwaye i-4 ka-4 i-Moore yongezwa ukuze ivaliwe kwaye ishushu ivaliwe nge-40 ° C ye-4h. Emva kokupholisa, ukukhulula i-methatharine egqithisileyo, ukuphanga, ukuqokelela amanqaku e-° Restation, fumana malunga ne-180g yeemveliso, kwaye umvuzo uya kuba malunga neepesenti ezingama-90. I-REAL STOPITION (kg / g) γ-butthibottin 980 Methyline (40%) 860.

Ukusebenza kunye nokugcinwa:

1. Indlela yokugcina

Gcina phantsi kwegesi eyomileyo, gcina isitya esitywiniweyo, kwaye sigcine kwindawo epholileyo neyomileyo.

2. Amanyathelo okhuseleko

Kulumkele ukubonakaliswa: kufuneka ufumane ukhokelo olukhethekileyo ngaphambi kokusetyenziswa. Kulumkele ukunxibelelana nolusu kunye namehlo. Kunqande ukuphefumla komphunga kunye nomsi. Sukusondela kumthombo womlilo. -Akutshaywa. Thatha amanyathelo okuthintela ukuqokelelwa kwe-static.

I-3. Izilumkiso zokugcina

Kukho indawo epholileyo kwisitoreji. Gcina isikhongozeli sivaliwe kwaye sigcine kwindawo eyomileyo nengenayo umoya. Isitya esivulekileyo kufuneka sitywinwe ngononophelo kwaye sigcine isikhundla esithe nkqo sokuthintela ukuvuza. Ukupheliswa kokulondolozwa kwe-infloces kunomdla kumswakama.
