Umkhiqizi Intengo Enhle I-N-VINYL PYRROLIDONE (NVP) CAS 88-12-0

I-NVP isetshenziswa kakhulu ukukhiqiza i-polyvinylpyrrolidone, esetshenziswa kakhulu emkhakheni wezokwelapha, imboni yansuku zonke yamakhemikhali kanye nokudla.

1. Isetshenziswa kakhulu kuzimonyo, okokuhlanza, imithi, izinto ezithinta izithombe neminye imikhakha

2. Okwamajeli esitayela sezinwele, ama-disinfectants ekhemisi, njll.

Inqubo yokulungiselela i-N-ethylene pheasone, kuhlanganise nezinyathelo ezilandelayo: 1. Ama-catalysts aphelelwe amanzi okulungiswa kwe-catalyst ephelelwe amanzi aqukethe i-silver sulfate, i-sodium aluminium silicate, i-white charcoal black, i-amproof, ne-multi-oxide.Isilinganiso sithi: 0.5 : 5: 3: 5: 10;Phakathi kwazo, ama-multi-oxides ayizingxube ezinhlanu ze-oxidation ezimbili -钒 ne-oxide, i-tin oxide, i-sex oxide, ne-manganese dioxide;Kuyingxube ye-oxidation dioxide emihlanu ne-oxide, i-oxidation emihlanu yesibili -钒 ne-tin oxide, i-oxidation emihlanu yesibili -钒 ne-manganese oxide ne-manganese dioxide.Ingxube ye-oxidation dioxide yesikhombisa ingu-0.2: 1: 2: 1. Izinyathelo zokukhiqiza ama-catalysts aphelelwe amanzi yilezi: hlanganisa isiliva sulfate, i-amproof, ne-multi-oxides ngokulingana, bese wengeza izikhathi ezingu-1 umthamo wamanzi acwecwe, lungisa i-pH. inani le-sulfuric acid namanzi e-ammonia ku-6.5 kuya ku-7, bese wengeza i-sodium silicine ne-sodium silicanate futhi ngokulingana nezilinganiso.Amalahle amhlophe amnyama, ashise futhi axutshwe ukuze enze isisombululo esifanayo;gudluza emanzini okugeza futhi uhlanganise isixazululo ukuze somile, somile ku-100-120 ° C ku-6 kuya ku-8h, bese ubhaka i-3 kuya ku-5h ku-400 ~ 450 ° C. 2. Ukulungiselela i-N-hydroxythylpylpyline (NHP) 1) Hlanganisa i-γ-butanol, i-ethanol eyodwa, ne-ammonia ngesilinganiso esingu-1.2: 1: 0.2, futhi isabela ku-0.5MPa no-40 ° C. , Yenza okuphakathi;2) Engeza isisefo samangqamuzana angu-0.1WT % kanye no-0.1WT % we-dilateyl dihal ether ukuze ukhuphule izinga lokushisa libe ngu-180 ° C ukuze ulenze liphelelwe amanzi ngo-12h esimweni esigciniwe;lokho okuchazwa njengokuchazwa;kuthiwani?Isisefo se-molecular 10xchemicalbook molecular sieve noma 13X molecular sieve.Le ndlela ikhethwa njengezisefo ze-molecular 10x;3) i-distillation ye-decompression, i-vacuum ingu-0.095MPa, futhi iqoqa ukucwiliswa kwendawo yokubilisa ye-210 kuya ku-216 ° C. I-Pyrodorrone;3. Ukusabela kokuphelelwa amanzi emzimbeni kwe-N-hydroxyetylpinol ukwenza i-distillation score etholwe ekulungiseni i-N-hydroxyethylpinols ibe isitimu, exutshwe negesi ye-alkaline, amagesi e-acetylene, ne-nitrogen ukuze kutholwe ingxube ye-gaseous impahla eluhlaza.Isilinganiso esixubile singu-1: 0.5: 0.1: 0.1;Yenza ingxube yegesi eluhlaza ngaphansi kwesimo se-reactor yombhede ongashintshi we-catalyst ephelelwe amanzi endaweni yokushisa engu-350 ° C, ingcindezi ye-0.01MPa kanye nesivinini segesi esingu-50-300H-1, kanye nokuphelelwa amandla kwamanzi emzimbeni endaweni ehleliwe. I-reactor yombhede I-catalyst ishisa ku-390 ° C. Ngemva kokusabela kokuphelelwa amanzi emzimbeni kufinyelela ebhalansi, umkhiqizo we-N-ethylene cephalopicone (NVP) ukhishwa ku-reactor yombhede ongashintshi.Amagesi ane-alkaline okungenani yi-ammonia, i-methylemine, i-dihamine, i-trothalmine, ne-ethimine.Yamukela indlela yokuhlaziya i-gas chromatography, esekelwe ku-γ-butthite njengezinga langaphakathi, i-ethanol njengezincibilikisi, kuhlaziye umkhiqizo we-N-ethylene cheedone olungiswe ngale ndlela, kubalwe izinga lokuguqulwa kwe-NHP, ukukhetha kwe-NVP, imali engenayo ye-NVP, isigaba saso segesi. isigaba sesigaba, lapho isigaba sesigaba segesi isigaba sesigaba sesigaba sesigaba segesi, isigaba saso segesi kwakuyizimo zokuhlola ze-Chromatographic: umtshina we-TCD, ikholomu yensimbi engagqwali, isixazululo sokulungisa i-poly acetic glycol tannite dilate, i-nitrogen ilayishiwe, i-silicanerization 102 umehluko omhlophe, izinga lokushisa legumbi le-gasification 280 ° C, izinga lokushisa lomtshina we-TCD 165 ° C, amakholomu, amakholomu, amakholomu Izinga lokushisa elingu-190 ° C;kubalwe ngokuhlaziywa kwe-chromatography yegesi: izinga lokuguqulwa kwe-NHP elingu-92.8 %, ukukhetha kwe-NVP okungu-91.5 %, kanye nemali engenayo ye-NVP engu-85.6 %.
