Uruganda Igiciro Cyiza N-VINYL PYRROLIDONE (NVP) CAS 88-12-0

NVP ikoreshwa cyane cyane mu gukora polyvinylpyrrolidone, ikoreshwa cyane mubijyanye n'ubuvuzi, imiti ya buri munsi n'inganda y'ibiribwa.

1. Ikoreshwa cyane mu kwisiga, ibikoresho byo kwisiga, imiti, ibikoresho bifotora hamwe nizindi nzego

2. Kumisatsi yo gutunganya imisatsi, imiti yica farumasi, nibindi.

Igikorwa cyo gutegura N-Ethylene pheasone, harimo nintambwe zikurikira: 1. Cataliseri idafite umwuma yo gutegura catisale idafite umwuma irimo sulfate ya silver, sodium aluminium silikatike, amakara yera yumukara, amproof, na okiside nyinshi. Umubare ni: 0.5: 5: 3: 5: 10; Muri byo, byinshi -oxide ni imvange eshanu za okiside eshanu - 钒 na oxyde, tin oxyde, oxyde de sexe, na dioxyde de manganese; Ni uruvange rwa dioxyde de oxyde eshanu na okiside, okiside eshanu ebyiri - 钒 na tin oxyde, okiside eshanu ebyiri - 钒 na oxyde ya manganese na dioxyde de manganese. Uruvange rwa dioxyde ya karindwi ya okiside ni 0.2: 1: 2: 1. Intambwe yumusaruro wa catisitiya idafite umwuma ni: kuvanga sulfate ya silver, amproof, na -oxide nyinshi mukigereranyo, hanyuma ukongeramo inshuro 1 ubwinshi bwamazi yatoboye, ugahindura agaciro ka pH agaciro ka acide sulfurike namazi ya amoniya kuri 6.5 kugeza kuri 7, hanyuma ukongeramo sodium silicine na sodium. Amakara yera ni umukara, ashyushye kandi akangurwa kugirango igisubizo kimwe; koga mu bwogero bw'amazi hanyuma uhuze igisubizo cyumye, cyumuke kuri 100-120 ° C kuri 6 kugeza 8h, hanyuma utekeshe kuri 3 kugeza 5h kuri 400 ~ 450 ° C. ) ibyasobanuwe nkuko byasobanuwe; ni iki kivugwa? Icyuma cya molekuline ni 10xchemicalbook igitabo cya molekulari cyangwa 13X ya molekile. Ubu buryo bwatoranijwe nka 10x ya molekile ya sikeri; 3) decompression distillation, vacuum ni 0.095MPa, kandi ikusanya distillation ya point de 210 kugeza 216 ° C. Pyrodorrone; 3. Kubura umwuma wa N-hydroxyetylpinol kugirango utange amanota ya distillation yabonetse mugutegura N-hydroxyethylpinol mu cyuka, ivanze na gaze ya alkaline, gaze ya acetylene, na azote kugirango ubone ibintu bivanze na gaze. Ikigereranyo kivanze ni 1: 0.5: 0.1: 0.1; Kora imyuka ya gazi ivanze ukurikije imiterere yigitanda gihamye cya catisitori idafite umwuma mubushyuhe bwa 350 ° C, umuvuduko wa 0.01MPa numuvuduko wa gaze wa 50-300H-1, hamwe no kubura umwuma wa dehidrasi mumashanyarazi yigitanda cyagenwe Catalizator yashyutswe kugeza kuri 390 ° C. Nyuma yo kubura umwuma wa NV etylene cephalopic. Imyuka ya alkaline nibura imwe muri ammonia, methylemine, dihamine, trothalmine, na Ethimine. Kwemeza uburyo bwo gusesengura gazi ya chromatografiya, ishingiye kuri γ-butthite nkibipimo byimbere, Ethanol nkibishishwa, yasesenguye ibicuruzwa bya N-Ethylene cheedone yateguwe nubu buryo, ibara igipimo cyo guhindura NHP, guhitamo NVP, amafaranga yinjira muri NVP, icyiciro cya fasi yicyiciro cya fonctionnement, icyiciro cya gazi ya polotike ya TCL. gukemura igisubizo, azote iremerewe, silicanerisation 102 itandukaniro ryera, ubushyuhe bwicyumba cya gazi 280 ° C, ubushyuhe bwa TCD bwerekana ubushyuhe 165 ° C, inkingi, inkingi, inkingi Ubushyuhe bwa 190 ° C; ubarwa nisesengura rya gazi chromatografiya: NHP igipimo cya 92.8%, guhitamo NVP 91.5%, na NVP yinjiza 85,6%.
