Umenzi wexabiso eliLungileyo i-N-VINYL PYRROLIDONE (NVP) CAS 88-12-0

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 ama-catalysts aphelileyo: xuba i-sulfate yesilivere, i-amproof, kunye ne-multi-oxides ngokulinganayo, uze udibanise amaxesha angama-1 umthamo wamanzi adibeneyo, ulungelelanise ixabiso le-pH le-sulfuric acid kunye ne-ammonia yamanzi kwi-6.5 kwaye yongeza i-sodium ye-sodium kunye ne-sodium kwi-7. umlinganiselo. Amalahle amhlophe amnyama, ashushu kwaye axutywe ukwenza isisombululo esifanayo; ugxobhoze kwindawo yokuhlambela amanzi kwaye udibanise isisombululo somile, some kwi-100-120 ° C kwi-6 ukuya kwi-8h, uze ubhaka i-3 ukuya kwi-5h kwi-400 ~ 450 ° C. 2. Ukulungiswa kwe-N-hydroxyethylpylpyline (NHP) 1) Hlanganisa i-γ-butanol, i-ammonianol enye, i-ammonianol enye: i-ammonianol enye: 0.2, kwaye isabela 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 kwi-reactor yebhedi ehleliweyo I-catalyst ishushu kwi-390 ye-dehydration ye-dehydration, ° i-dehydration ye-390 ° i-dehydration. i-cephalopicone (NVP) imveliso ikhutshwa 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 ye-cheedone elungiselelwe yile ndlela, ibalwe izinga lokuguqulwa kwe-NHP, ukukhetha kwe-NVP, ingeniso ye-NVP, yeyiphi igesi yesigaba sesigaba sesigaba sesigaba, apho i-gas phase phase phase phasesdetect, yiyiphi i-STD yesigaba sesigaba sovavanyo ikholamu yensimbi, i-poly acetic glycol tannite i-dilate isisombululo sokulungisa, i-nitrogen ilayishiwe, i-silicanerization 102 umahluko omhlophe, i-gasification yegumbi lokushisa i-280 ° C, iqondo lokushisa le-TCD detector 165 ° C, iikholamu, iikholamu, iikholamu Ubushushu be-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%.
