Umvelisi ofanelekileyo Ixabiso elilungileyo N-Vinyl Pyralidone (NVP) I-88-12-0

I-NVP isetyenziselwa ukuvelisa i-Polyvinylpylpylidone, esetyenziswe ngokubanzi kwicandelo leyeza, ishishini lokutya nemizi-mveliso.

1. Isetyenziswe ngokubanzi kwiziko lezicotho, izicoci, amayeza, izinto ezifotileyo kunye nezinye iindawo

I-2. Kwi-gesel ye-geseli yeenwele, iintsholongwane zekhemisi, njl.

The preparation process of N-ethylene pheasone, including the following steps: 1. The dehydrated catalysts of the preparation of dehydrated catalyst contain silver sulfate, sodium aluminum silicate, white charcoal black, amproof, and multi-oxide. Inxalenye yile: 0.5: 5: 3: 10; Phakathi kwazo, ii-axider ezintlanu zee-oxidation zantlanu ezimbini ze-oxidation widation ezimbini ezimbini ze-Oxide, iTin Axide, i-Manganese Dioxide; Ngumxube we-oxidation dabicade, oxide, i-tidasional maide, axidation ter, i-manganese oxide ne-manganese diokside. Umxube we-oxidetion yesixhenxe ngu-0.2: 1: 2: 1. Amanyathelo emveliso ye-Deallysts yehlile: xuba isilivere, udibanise umthamo wamanzi amnandi, hlengahlengisa i-PH Ixabiso le-sulfuric acid kunye ne-ammonia amanzi ukuya kwi-6.5 ukuya kwi-7, kwaye emva koko wongeza i-sodium asiconine kunye ne-sodium asiconate kunye ne-sodium silicoate kunye nenqanaba ukuya kwinqanaba. I-charcoal emhlophe imnyama, ishushu kwaye ishukunyisiwe ukuba yenze isisombululo selinganiso; Shuma kwindawo yokuhlambela yamanzi kwaye ufihle isisombululo esomileyo, some kwi-100 le-420 ° C ukuba se-6 ukuya kwi-8 ukuya kwe-500 ° 45 ° C. 2. Hlanganisa i-But-Butanol, i-ethanol enye, kunye ne-ammonia kumyinge we-1.2: 1: 0.2, kwaye iphinde isebenze kwi-0.5MPA kunye ne-40 ° Yenza isixeko esiphakathi; 2) Yongeza i-SEALEP ye-Molecular ye-0.1WT% kunye ne-0.1WT% ye-Dilateyl Dihal Ether ukuya kwi-180 ° C ukuba isebenze nge-12h kwilizwe eligciniweyo; into echaziweyo njengoko ichaziwe; Yintoni echaziweyo? I-SIeCrea SEieve yi-10xchemicalbook molecrour Sieve okanye i-13x molersur. Le ndlela ikhethwe njenge-10x i-sies; 3) Ukudibana kwe-decompingo, i-vacuum yi-0.095MPA, kwaye iqokelela isiseko sendawo yokubila i-210 ukuya kwi-216 ° C. Pyrodorrone; 3. Ukupheliswa kwempahla emzimbeni ye-N-hydrox'x'xrox'x'xroxypinalinpinol ukwenza inqaku lokuhlangana elifunyenwe kwi-N-HydroxyEzylPinPinpinals kwi-Steam, ixutywe ne-Alkaline igesi, kunye ne-nitrogen ukuze ifumane umxube wezinto ezisemgangathweni. Umlinganiselo odityanisiweyo ngu-1: 0.5: 0.1: 10.1: 0,1; Yenza umxube wemicimbi yegesi phantsi kwemeko yesandla esisigxina sendawo yokulala esihlayo kwiqondo lokushisa elinama-350 ° C, ingcinezelo ye-0.0MPA kunye nesantya segesi esiyi-1-300h-1, kunye nehyding yehyding Ukhuphiswano lwebhedi I-Catalyst ifudunyele i-390 ° C. Emva kokupheliswa komzimba kufikelela kwibhalansi, i-n-ithonene Imveliso ye-ciphalopicone (NVP) ikhutshiwe kwityala elimisiweyo yebhedi. Igesi yeAlkaline inye ye-ammonia, iMenyamine, i-Diehamine, iTrothalmine, nase-Inteimine. Indlela yokwamkela igesi yegesi, esekwe kwi-γ-bhetite njengomgangatho wangaphakathi, i-ethanol njengoko imveliso ye-N-Ebanone elungiselelwe yile ndlela, ithathe ukukhetha kwe-NHP, iNgeniso ye-NHP, yeSigaba seSigaba seGal Inqanaba lesigaba, leSigaba seSigaba seSigaba seSigaba seSigaba seSigaba seSubs seSigaba seSigaba seSigaba sePasi, iSigaba seSigaba seGalo yayiyimeko yovavanyo lwe-chromatographic: ikholamu, i-poly acetic glycol ganti yesisombululo sokulungisa, i-nitrogen ilayishwe, i-silicaner 105 ° C, iikholamu, i-CCD, iqondo lobushushu le-190 ° C; Ibaliwe kuhlalutyo lwe-chromatography yegesi: i-NHP yokuNguqula kwe-92.8%, ukukhetha i-91.5%, kunye neNgxelo ye-NVP ye-85.6%.
