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. Masitepe opangira zopangira zowonongeka ndi: kusakaniza siliva sulfate, amproof, ndi multi-oxides muyeso, kenaka onjezerani 1 nthawi ya madzi osungunuka, sinthani pH mtengo wa sulfuric acid ndi ammonia madzi ku 6.5 kenaka yonjezerani sodium sulfate ndi silicon 7 ndi sodium 7. 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-hydroxyethylpylpyline (NHP) 1) Sakanizani γ-butanol ndi 1 ammonianol chiŵerengero: 1 ammonianol: 1 ammonianol: 1. 0.2, ndipo amachitira pa 0.5MPa ndi 40 ° C. , Pangani wapakatikati; 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 cha anakonza bedi riyakitala wa chothandizira madzi m'thupi pa kutentha kwa 350 ° C, kuthamanga kwa 0.01MPa ndi mpweya liwiro 50-300H-1, ndi kuchepa madzi m'thupi mu anakonza bedi riyakitala Chothandizira ndi usavutike mtima kuti 390 Nthenda ya madzi m'thupi, n'kufika 390 ° C. cephalopicone (NVP) mankhwala amatulutsidwa kuchokera pa 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 imeneyi, kuwerengetsera NHP kutembenuka mlingo, NVP selectivity, NVP ndalama, amene mpweya gawo gawo gawo gawo, amene mpweya gawo gawo gawo gawo lofufuza zinthu anali: TROSS GATOgraphic gawo gawo mayeso gawo, amene chrographic gamatographic gawo chigawo choyesa: ndime yachitsulo, poly acetic glycol tannite dilate fixing solution, nayitrogeni yodzaza, silicanerization 102 yoyera kusiyana, gasification chipinda kutentha 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 %.
