Uruganda igiciro cyiza n-vinyl pyrrodone (nvp) cas 88-12-0

NVP ikoreshwa cyane cyane kubyara PolyvinylprPrOldone, ikoreshwa cyane mumiti yimiti, inganda za buri munsi.

1. Byakoreshejwe cyane muri kwisiga, kwibikwa, ubuvuzi, ibikoresho byaho bitose nibindi bice

2. Kubijyanye na gels yimisatsi, abatandukanya farumasi, nibindi

Inzira yo gutegura N-REOCYENE Pheasone, harimo intambwe zikurikira: 1. Imyanya yo mu butayu bwo gutegura umusemburo urwaye, sodinum iseswa, amakara ya sodium arasenyuka, umukara, na oxide, na oxide, na oxide, na oxide. Umubare ni: 0.5: 5: 5: 10: 10; Muri bo, ibipimo byinshi ni imvange eshanu zivanze za okiside ebyiri - 钒 na okide, amabati, amafi yumubonano mpuzabitsina, na dioxyde de mangane; Ni uruvange rwa diyoxide eshanu na oxide, okiside eshanu ebyiri - 钒 na TIN oxide, okiside eshanu ebyiri - 钒 na dioxyde de manganer na dioxyde de mangane. Uruvange rwa dioxyde ya karindwi ni 0.2: 1: 2: 1. Intambwe Yonda yumurongo wa feza, na byinshi, hamwe ninshuro nyinshi amazi yatowe, guhindura pH Agaciro ka aside sulfuric na Amazi ya Ammonia kugeza 6.5 kugeza 7, hanyuma wongere sodimine silicine na sodium siliconate na sodional Kuri byinshi. Amakara yera ni umukara, ashyushye kandi ashingora kugirango akore igisubizo kimwe; Kangura mu bwogero bw'amazi kandi utondeke igisubizo cyo gukama, wuma ku 100-120 ° C kuri 6 kugeza kuri 8h saa 400 ~ 450. Kuvanga γ-Butanol, Ethanol imwe, na Ammomiya mugihe cya 1.2: 1: 0.2, kandi yitwara kuri 0.5mpa na 40 ° C., kora hagati; 2) Ongeraho molecular yatunganiza 0.1WT% na 0.1WT% ya Dilatoyl dihal kugirango yongere ubushyuhe kugeza 180 ° C kugirango ibone umwuma kuri 12h mugihugu cyagumishijwe; Ibisobanuwe nkuko byasobanuwe; Ni iki kivugwa? MoleCular Sieve ni 10xchemicalbook molecular yatunganiza cyangwa 13x molecular yatunganiza. Ubu buryo bwatoranijwe nka 10x silekale ya molekile; 3) Amacakubiri ya decompression, icyuho ni 0.095mpa, kandi ikusanya agahinda ingingo zibitse za 210 kugeza 216 ° C. Pyrodorrone; 3. Umwuma reaction ya N-Hydroxyylpinol kugirango hamenyekane amanota yo gutandukana yabonetse mugutegura N-HydroxyEthylpinols, ivanze na gaze ya alkaline, na alliggen kugirango ibone uruvange rwibikoresho bya gaze. Ikigereranyo kivanze ni 1: 0.5: 0.1: 0.1; Kora ibikoresho bya gaze mbisi bifatika munsi yigitanda gihamye reacyst yubushyuhe bwa 350 ° C, umuvuduko wa 0.01mpa na RATH-1, nuburaro bwuburaro Uburiri bwa reacttor umusemburo buhambiwe 390 ° C. Nyuma yimyitwarire ya Umwuma igera kuringaniza, N-Etylene Cephalopicone (NVP) ibicuruzwa bisezerewe mu buriri buhamye. Imyuka ya alkaline nibura rimwe muri Ammonia, Methylemine, Dimine, Trothalmine, na motimune. Emera uburyo bwa gaze ya chromatography, ishingiye kuri γ-Arikothite nk'uburinganire bw'imbere, Ethanol nk'ibicuruzwa bya NHP, byasesengura igipimo cya NDP, NVP icyiciro cya GEAPE Icyiciro cya Prose, muri kiriya cyiciro cya gaze icyiciro cya kabiri Icyiciro, muri ibyo byiciro bya gaze byari icyiciro cy'ibizamini bya chromatografi: TCD detector, ibyuma bidafite ishingiro, aceitic glycol tannite dilate ikosora, azote ya kiliki ya gitandukanye, C, Inkingi zitandukanye Ubushyuhe bwa 160 ° C; kubarwa nisesengura rya gaze ya chromatografi: Igipimo cya NHP cya 92.8%, NVP Guhitamo 91.5%, na NVP amafaranga ya 85,6%.
