Mtengo Wabwino Wopanga N-VINYL PYRROLIDONE (NVP) CAS 88-12-0

NVP imagwiritsidwa ntchito kwambiri popanga polyvinylpyrrolidone, yomwe imagwiritsidwa ntchito kwambiri m'magawo azachipatala, mankhwala atsiku ndi tsiku komanso mafakitale azakudya.

1. Amagwiritsidwa ntchito kwambiri mu zodzoladzola, sopo, mankhwala, zipangizo zowunikira kuwala ndi zina

2. Ma gels okongoletsa tsitsi, mankhwala ophera tizilombo toyambitsa matenda ku pharmacy, ndi zina zotero.

Njira yokonzekera N-ethylene pheasone, kuphatikizapo njira zotsatirazi: 1. Ma catalyst ouma madzi omwe amakonzedwa ndi catalyst wouma ali ndi siliva sulfate, sodium aluminium silicate, white charcoal black, amproof, ndi multi-oxide. Chiŵerengero chake ndi: 0.5 : 5: 3: 5: 10; Pakati pawo, ma multi-oxide ndi osakaniza asanu a oxidation awiri -钒 ndi oxide, tin oxide, sex oxide, ndi manganese dioxide; Ndi osakaniza asanu a oxidation dioxide ndi oxide, asanu a oxidation awiri -钒 ndi tin oxide, asanu a oxidation awiri -钒 ndi manganese oxide ndi manganese dioxide. Osakaniza asanu ndi awiri a oxidation dioxide ndi 0.2: 1: 2: 1. Masitepe opangira ma catalyst ouma madzi ndi awa: sakanizani silver sulfate, amproof, ndi multi-oxides molingana, kenako onjezerani ka 1 kuchuluka kwa madzi osungunuka, sinthani pH ya sulfuric acid ndi madzi a ammonia kufika pa 6.5 mpaka 7, kenako onjezerani sodium silicine ndi sodium siliconate komanso molingana ndi kuchuluka. Makala oyera ndi akuda, otenthedwa ndi kusonkhezeredwa kuti apange yankho lofanana; sakanizani mu bafa la madzi ndikusakaniza yankho kuti liume, liume pa 100-120 ° C kwa maola 6 mpaka 8, kenako phikani kwa maola 3 mpaka 5 pa 400 ~ 450 ° C. 2. Kukonzekera N-hydroxyethylpyline (NHP) 1) Sakanizani γ-butanol, ethanol imodzi, ndi ammonia pa chiŵerengero cha 1.2: 1: 0.2, ndipo limachitapo kanthu pa 0.5MPa ndi 40 ° C. , Pangani pakati; 2) Onjezani sieve ya molecular ya 0.1WT % ndi 0.1WT % ya dilateyl dihal ether kuti muwonjezere kutentha kufika pa 180 ° C kuti iume ndi maola 12 mu mkhalidwe wosungidwa; zomwe zafotokozedwa monga zafotokozedwa; zomwe zatchulidwa? Sieve ya molecular ndi sieve ya molecular ya 10xchemicalbook kapena sieve ya molecular ya 13X. Njirayi imasankhidwa ngati sieve ya molecular ya 10x; 3) kusungunuka kwa mpweya wochepa, vacuum ndi 0.095MPa, ndipo imasonkhanitsa kusungunuka kwa kutentha kwa 210 mpaka 216 ° C. Pyrodorrone; 3. Kutuluka kwa madzi m'thupi kwa N-hydroxyetylpinol kuti apange kuchuluka kwa madzi m'thupi komwe kumapezeka pokonzekera N-hydroxyethylpinols kukhala nthunzi, kusakanizidwa ndi mpweya wa alkaline, mpweya wa acetylene, ndi nayitrogeni kuti mupeze kusakaniza kwa zinthu zopangira mpweya. Chiŵerengero chosakanikirana ndi 1: 0.5: 0.1: 0.1; Pangani kusakaniza kwa zinthu zopangira mpweya pansi pa mkhalidwe wa chosinthira mpweya chokhazikika cha chosinthira madzi pa kutentha kwa 350 ° C, kuthamanga kwa 0.01MPa ndi liwiro la mpweya la 50-300H-1, ndi kutuluka kwa madzi m'thupi mu chosinthira mpweya chokhazikika. Chothandizira chimatenthedwa kufika pa 390 ° C. Pambuyo poti madzi atha kufika pamlingo woyenera, chinthu cha N-ethylene cephalopicone (NVP) chimatulutsidwa kuchokera ku chosinthira mpweya chokhazikika. Mpweya wa alkaline ndi umodzi mwa ammonia, methylemine, dihamine, trothalmine, ndi ethimine. Gwiritsani ntchito njira yowunikira mpweya wa chromatography, kutengera γ-butthite monga muyezo wamkati, ethanol ngati zosungunulira, kusanthula mankhwala a N-ethylene cheedone okonzedwa ndi njira iyi, kuwerengera kuchuluka kwa kusintha kwa NHP, kusankha kwa NVP, ndalama za NVP, zomwe gawo la gawo la gasi, zomwe gawo la gawo la gasi, zomwe gawo la gawo la gasi linali mikhalidwe yoyesera ya Chromatographic: chowunikira cha TCD, mzati wosapanga dzimbiri, yankho lokonza la polyacetic glycol tannite dilate, nayitrogeni yadzaza, silicanerization 102 white contrast, kutentha kwa chipinda cha gasification 280 ° C, kutentha kwa chowunikira cha TCD 165 ° C, mzati, mzati, mzati Kutentha kwa 190 ° C; kuwerengedwa posanthula kwa chromatography ya gasi: Kuchuluka kwa kusintha kwa NHP kwa 92.8%, kusankha kwa NVP 91.5%, ndi ndalama za NVP za 85.6%.
