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

NVP imagwiritsidwa ntchito makamaka popanga polyvinylpyrrolidone, yomwe imagwiritsidwa ntchito kwambiri m'mafakitale azamankhwala, mankhwala a tsiku ndi tsiku ndi chakudya.

1. Amagwiritsidwa ntchito kwambiri muzodzoladzola, zotsukira, mankhwala, zinthu zowoneka bwino ndi zina.

2. Kwa ma gel opangira tsitsi, mankhwala ophera tizilombo, etc.

Kukonzekera kwa N-ethylene pheasone, kuphatikizapo masitepe otsatirawa: 1. Zomwe zimapangidwira zowonongeka zowonongeka zowonongeka zimakhala ndi siliva sulfate, sodium aluminium silicate, makala oyera akuda, amproof, ndi multi-oxide.Chigawo chake ndi: 0.5 : 5: 3: 5: 10;Mwa iwo, ma multi-oxides ndi osakaniza asanu a oxidation asanu awiri -钒 ndi okusayidi, tin oxide, sex oxide, ndi manganese dioxide;Ndi osakaniza asanu oxidation dioxide ndi oxide, asanu oxidation awiri -钒 ndi tin oxide, asanu oxidation awiri -钒 ndi manganese oxide ndi manganese dioxide.Kusakaniza kwachisanu ndi chiwiri kwa oxidation dioxide ndi 0.2: 1: 2: 1. Njira zopangira zopangira madzi opanda madzi ndi: sakanizani siliva sulfate, amproof, ndi multi-oxides molingana, kenaka onjezerani 1 nthawi ya madzi osungunuka, sinthani pH. mtengo wa sulfuric acid ndi ammonia madzi ku 6.5 mpaka 7, ndiyeno onjezerani sodium silicine ndi sodium silicanate ndi molingana ndi kuchuluka.Makala oyera ndi akuda, amatenthedwa ndikugwedezeka kuti apange njira yofanana;kusonkhezera mu osamba madzi ndi condense njira youma, youma pa 100-120 ° C kwa 6 mpaka 8h, ndiyeno kuphika kwa 3 mpaka 5h pa 400 ~ 450 ° C. 2. Kukonzekera N-hydroxythylpylpyline (NHP) 1) Sakanizani γ-butanol, ethanol imodzi, ndi ammonia pa chiŵerengero cha 1.2: 1: 0.2, ndipo amachitira pa 0.5MPa ndi 40 ° C. , Pangani chapakati;2) Onjezani sieve ya molekyulu ya 0.1WT% ndi 0.1WT% ya dilateyl dihal ether kuti muwonjezere kutentha kwa 180 ° C kuti ikhale yopanda madzi ndi 12h m'malo osungidwa;zomwe zikufotokozedwa monga momwe zafotokozedwera;chatchulidwa chiyani?Sieve ya molekyulu ndi 10xchemicalbook molecular sieve kapena 13X molecular sieve.Njirayi imasankhidwa ngati sieve 10x ya maselo;3) decompression distillation, vacuum ndi 0.095MPa, ndipo amasonkhanitsa distillation wa kuwira mfundo 210 kuti 216 ° C. Pyrodorrone;3. The kuchepa madzi m'thupi anachita N-hydroxyetylpinol kuti distillation mphambu analandira pokonza N-hydroxyethylpinols mu nthunzi, wothira mpweya wamchere, mpweya acetylene, ndi nayitrogeni kupeza mpweya yaiwisi osakaniza.Chiŵerengero chosakanikirana ndi 1: 0.5: 0.1: 0.1;Pangani mpweya zopangira zosakaniza pansi pa chikhalidwe chokhazikika bedi riyakitala wa chothandizira wopanda madzi m'thupi pa kutentha kwa 350 ° C, kuthamanga kwa 0.01MPa ndi liwiro la mpweya 50-300H-1, ndi kuchepa madzi m'thupi mu zokhazikika. Bedi reactor Chothandizira chimatenthedwa mpaka 390 ° C. Pambuyo pa kuchepa kwa madzi m'thupi kufika pamtunda, mankhwala a N-ethylene cephalopicone (NVP) amachotsedwa ku bedi lokhazikika.Mipweya ya alkaline ndi imodzi mwa ammonia, methylemine, dihamine, trothalmine, ndi ethimine.Adopt mpweya chromatography kusanthula njira, zochokera γ-butthite monga muyezo mkati, Mowa monga zosungunulira, kusanthula N-ethylene cheedone mankhwala okonzedwa ndi njira iyi, anawerengetsera NHP kutembenuka mlingo, NVP selectivity, NVP ndalama, amene gasi gawo gawo. gawo, lomwe gawo la gasi gawo la gawo la gawo, lomwe gawo la gasi linali chromatographic mayeso: chowunikira cha TCD, chitsulo chosapanga dzimbiri, polyacetic glycol tannite dilate fixing solution, nayitrogeni yodzaza, silicanerization 102 kusiyanitsa koyera, kutentha kwa chipinda cha gasification 280 ° C, TCD detector kutentha 165 ° C, mizati, mizati, mizati Kutentha kwa 190 ° C;kuwerengeredwa ndi kusanthula kwa chromatography ya gasi: Kutembenuka kwa NHP kwa 92.8 %, kusankha kwa NVP 91.5 %, ndi ndalama za NVP za 85.6 %.
