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

I-NVP isetshenziswa kakhulu ukukhiqiza i-polyvinylpyrrolidone, esetshenziswa kabanzi emikhakheni yezokwelapha, yamakhemikhali yansuku zonke kanye nemboni yokudla.

1. Kusetshenziswa kabanzi ezimonyweni, ezihlanzweni, emithini, ezintweni ezithinta ukukhanya kanye neminye imikhakha

2. Amajeli okulungisa izinwele, izibulali-magciwane zasekhemisi, njll.

Inqubo yokulungiselela i-N-ethylene pheasone, kufaka phakathi izinyathelo ezilandelayo: 1. Ama-catalyst aphelelwe amanzi okulungiselela i-catalyst ephelelwe amanzi aqukethe i-silver sulfate, i-sodium aluminium silicate, i-white charcoal black, i-amproof, kanye ne-multi-oxide. Isilinganiso singu-0.5: 5: 3: 5: 10; Phakathi kwawo, ama-multi-oxide ayingxube emihlanu yama-oxidation amabili ne-oxide amahlanu, i-tin oxide, i-sex oxide, kanye ne-manganese dioxide; Kuyingxube ye-oxidation dioxide emihlanu ne-oxide, ama-oxidation amabili ne-tin oxide amahlanu, ama-oxidation amabili ne-manganese oxide amahlanu ne-manganese dioxide. Ingxube ye-oxidation dioxide yesikhombisa ingu-0.2: 1: 2: 1. Izinyathelo zokukhiqiza zama-catalyst aphelelwe amanzi yilezi: hlanganisa i-silver sulfate, i-amproof, kanye nama-multi-oxides ngokulingana, bese ufaka ivolumu yamanzi acwebezelwe kanye, lungisa inani le-pH le-sulfuric acid namanzi e-ammonia libe ngu-6.5 kuya ku-7, bese ufaka i-sodium silicine kanye ne-sodium siliconate futhi ngokulingana nezilinganiso. Amalahle amhlophe amnyama, afudunyezwe futhi axutshwe ukuze kwenziwe isisombululo esifanayo; hlanganisa emanzini bese uqinisa isisombululo ukuze some, some ku-100-120 ° C amahora angu-6 kuya kwangu-8, bese ubhaka amahora angu-3 kuya kwangu-5 ku-400 ~ 450 ° C. 2. Ukulungiswa kwe-N-hydroxyethylpylpyline (NHP) 1) Hlanganisa i-γ-butanol, i-ethanol eyodwa, kanye ne-ammonia ngesilinganiso esingu-1.2: 1: 0.2, bese uphendula ku-0.5MPa kanye no-40 ° C. , Yenza okuphakathi; 2) Engeza isihlungi sama-molecule esingu-0.1WT % kanye no-0.1WT % we-dilateyl dihal ether ukwandisa izinga lokushisa libe ngu-180 ° C ukuze linciphe ngamahora angu-12 esimweni esigciniwe; yini echazwa njengokuchazwe; yini eshiwoyo? Isihlungi sama-molecule siyi-10xchemicalbook molecular sieve noma i-13X molecular sieve. Le ndlela ikhethwa njengezihlungi zama-molecule ezingu-10x; 3) i-decompression distillation, i-vacuum ingu-0.095MPa, futhi iqoqa i-distillation yephuzu lokubila elingu-210 kuya ku-216 ° C. I-Pyrodorrone; 3. Ukusabela kokuphelelwa amanzi emzimbeni kwe-N-hydroxyetylpinol ukwenza isilinganiso sokuphelelwa amanzi esitholakala ekulungiseleleni i-N-hydroxyethylpinols ibe umusi, ixutshwe negesi ye-alkaline, amagesi e-acetylene, kanye ne-nitrogen ukuthola ingxube yezinto zokusetshenziswa eziluhlaza. Isilinganiso esixubile singu-1: 0.5: 0.1: 0.1; Yenza ingxube yezinto zokusetshenziswa eziluhlaza emoyeni ngaphansi kwesimo se-reactor yombhede egxilile ye-catalyst ephelelwe amanzi emzimbeni ekushiseni okungu-350 ° C, ingcindezi engu-0.01MPa kanye nesivinini segesi esingu-50-300H-1, kanye nokuphelelwa amanzi emzimbeni kwe-reactor yombhede egxilile. I-catalyst ishiswa ku-390 ° C. Ngemva kokuba ukusabela kokuphelelwa amanzi emzimbeni sekufinyelele ibhalansi, umkhiqizo we-N-ethylene cephalopicone (NVP) ukhishwa kwi-reactor yombhede egxilile. Amagesi e-alkaline okungenani ayi-ammonia, i-methylemine, i-dihamine, i-trothalmine, kanye ne-ethimine. Sebenzisa indlela yokuhlaziya i-gas chromatography, esekelwe ku-γ-butthite njengendinganiso yangaphakathi, i-ethanol njenge-solvents, uhlaziye umkhiqizo we-N-ethylene cheedone olungiselelwe yile ndlela, ubale izinga lokuguqulwa kwe-NHP, ukukhetha kwe-NVP, imali engenayo ye-NVP, okuyisigaba sesigaba sesigaba segesi, okuyisigaba sesigaba sesigaba sesigaba segesi, okuyisigaba sesigaba segesi esasiyisimo sokuhlolwa kwe-Chromatographic: Umtshina we-TCD, ikholomu yensimbi engagqwali, isixazululo sokulungisa i-poly acetic glycol tannite dilate, i-nitrogen ilayishiwe, i-silicanerization 102 ukungafani okumhlophe, izinga lokushisa legumbi le-gasification 280 ° C, izinga lokushisa lomtshina we-TCD 165 ° C, amakholomu, amakholomu, amakholomu Izinga lokushisa lika-190 ° C; libalwa ngokuhlaziywa kwe-gas chromatography: Izinga lokuguqulwa kwe-NHP elingu-92.8%, ukukhetha kwe-NVP okungu-91.5%, kanye nemali engenayo ye-NVP engu-85.6%.
