Usetyenziso lwe-NVP
I-NVP isetyenziswa ikakhulu ukuvelisa i-polyvinylpyrrolidone, esetyenziswa kakhulu kwiinkalo zamayeza, iikhemikhali zemihla ngemihla kunye neshishini lokutya.
1. Isetyenziswa kakhulu kwizinto zokuthambisa, ezokucoca, amayeza, izinto ezithatha ifoto kunye namanye amacandelo.
2. Iigels zokulungisa iinwele, i-pharmacy disinfectants, njl.
Inkqubo yokulungiselela i-N-ethylene pheasone, kubandakanywa nala manyathelo alandelayo: 1. I-catalysts ye-dehydrated yokulungiselela i-catalyst dehydrated iqulethe i-sulfate yesilivere, i-sodium aluminium silicate, i-charcoal emhlophe emnyama, i-amproof, kunye ne-multi-oxide.Umlinganiselo ngu: 0.5 : 5: 3: 5: 10;Phakathi kwazo, i-multi-oxides yimixube emihlanu ye-oxidation emibini-钒 kunye ne-oxide, i-tin oxide, i-sex oxide, kunye ne-manganese dioxide;Ingumxube we-oxidation dioxide emihlanu kunye ne-oxide, i-oxidation emihlanu ezimbini -钒 kunye ne-tin oxide, i-oxidation emihlanu ezimbini -钒 kunye ne-manganese oxide kunye ne-manganese dioxide.Umxube wesixhenxe we-oxidation dioxide ngu-0.2: 1: 2: 1. Amanyathelo okuvelisa i-catalysts dehydrated are: xuba i-sulfate yesilivere, i-amproof, kunye ne-multi-oxides ngokomlinganiselo, uze udibanise amaxesha angama-1 umthamo wamanzi adibeneyo, ulungelelanise i-pH. ixabiso le-asidi ye-sulfuric kunye namanzi e-ammonia ukuya kwi-6.5 ukuya kwi-7, kwaye emva koko wongeza i-sodium silicine kunye ne-siliconate ye-sodium kunye nokulinganisa ngokulinganayo.Amalahle amhlophe amnyama, ashushu kwaye axutywe ukwenza isisombululo esifanayo;ugxobhoze kwindawo yokuhlambela amanzi kwaye udibanise isisombululo somile, somile kwi-100-120 ° C kwi-6 ukuya kwi-8h, uze ubhaka i-3 ukuya kwi-5h kwi-400 ~ 450 ° C. 2. Ukulungiswa kwe-N-hydroxythylpylpyline (NHP) 1) Hlanganisa i-γ-butanol, i-ethanol enye, kunye ne-ammonia kumlinganiselo we-1.2: 1: 0.2, kwaye iphendule kwi-0.5MPa kunye ne-40 ° C. , Yenza i-intermediate;I-2) Yongeza i-molecular sieve ye-0.1WT% kunye ne-0.1WT% ye-dilateyl dihal ether ukunyusa izinga lokushisa ukuya kwi-180 ° C ukuze ikhuphe amanzi nge-12h kwimeko egciniweyo;oko kuchazwa njengoko kuchaziwe;kukhankanywa ntoni?Isihluzo semolekyuli yi-10xchemicalbook ye-molecular sieve okanye i-13X ye-molecular sieve.Le ndlela ikhethwe njenge-10x ye-molecular sieves;3) i-decompression distillation, i-vacuum yi-0.095MPa, kwaye iqokelela i-distillation yendawo yokubilisa ye-210 ukuya kwi-216 ° C. I-Pyrodorrone;3. I-reaction ye-dehydration ye-N-hydroxyetylpinol ukwenza i-distillation score efunyenwe ekulungiseleleni i-N-hydroxyethylpinols ibe ngumphunga, ixutywe negesi ye-alkaline, iigesi ze-acetylene, kunye ne-nitrogen ukufumana umxube we-gaseous ekrwada.Umlinganiselo odibeneyo ngu-1: 0.5: 0.1: 0.1;Yenza umxube we-gaseous ekrwada phantsi kwemeko ye-reactor yebhedi esisigxina ye-catalyst dehydrated kwiqondo lokushisa lama-350 ° C, uxinzelelo lwe-0.01MPa kunye nesantya segesi se-50-300H-1, kunye nokuphelelwa ngamanzi emzimbeni kwindawo emiselweyo. I-bed reactor I-catalyst ifudumala ukuya kwi-390 ° C. Emva kokuba i-dehydration reaction ifikelele kwi-balance, i-N-ethylene cephalopicone (NVP) imveliso ikhutshwe kwi-reactor yebhedi esisigxina.Iigesi ze-alkaline ubuncinane enye ye-ammonia, i-methylemine, i-dihamine, i-trothalmine, kunye ne-ethimine.I-Adopt gas chromatography analysis method, esekelwe kwi-γ-butthite njengomgangatho wangaphakathi, i-ethanol njenge-solvents, ihlalutye imveliso ye-N-ethylene cheedone elungiselelwe le ndlela, ibala izinga lokuguqulwa kwe-NHP, ukukhetha kwe-NVP, ingeniso ye-NVP, apho isigaba segesi segesi. isigaba sesigaba, apho isigaba segesi sesigaba sesigaba sesigaba sesigaba sesigaba, apho isigaba segesi isigaba sesigaba segesi yayizimeko zovavanyo lweChromatographic: i-TCD detector, ikholomu yensimbi engenasici, isisombululo sokulungisa i-poly acetic glycol tannite dilate, i-nitrogen ilayishiwe, i-silicanerization 102 umahluko omhlophe, i-gasification yegumbi lokushisa 280 ° C, TCD detector iqondo lobushushu 165 ° C, iintsika, iintsika, iikholamu Ubushushu 190 ° C;ibalwa ngohlalutyo lwe-chromatography yegesi: izinga lokuguqulwa kwe-NHP ye-92.8%, ukukhetha kwe-NVP 91.5%, kunye nengeniso ye-NVP ye-85.6%.
