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.

1. Ikoreshwa cyane mumavuta yo kwisiga, ibikoresho byo kwisiga, imiti, ibikoresho bifotora hamwe nibindi bice

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

Igikorwa cyo gutegura pheasone ya N-Ethylene, harimo nintambwe zikurikira: 1. Cataliside idafite umwuma wo gutegura catisale idafite umwuma irimo sulfate ya silver, sodium aluminium silikate, 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 manganese oxyde 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 ugereranije, hanyuma ukongeramo inshuro 1 ubwinshi bwamazi yatoboye, uhindure pH agaciro ka acide sulfurike n'amazi ya amoniya kuri 6.5 kugeza 7, hanyuma ukongeramo sodium silicine na sodium siliconate kandi ugereranije nuburinganire.Amakara yera ni umukara, ashyushye kandi akangurwa kugirango igisubizo kimwe;koga mu bwogero bw'amazi hanyuma uhuze igisubizo cyumye, cyumutse kuri 100-120 ° C kuri 6 kugeza 8h, hanyuma utekeshe kuri 3 kugeza 5h kuri 400 ~ 450 ° C. 2. Gutegura N-hydroxyethylpylpyline (NHP) 1) Kuvanga γ-butanol, Ethanol imwe, na ammonia ku kigereranyo cya 1.2: 1: 0.2, hanyuma igakora kuri 0.5MPa na 40 ° C., Kora intera;)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. Imyunyu ngugu ya N-hydroxyetylpinol kugirango itange amanota ya distillation yabonetse mugutegura N-hydroxyethylpinol mu cyuka, ivanze na gaze ya alkaline, gaze ya acetylene, na azote kugirango ibone ibintu bivanze na gaze.Ikigereranyo kivanze ni 1: 0.5: 0.1: 0.1;Kora imyuka ya gazi ivanze ukurikije imiterere yuburiri butajegajega bwa catisale idafite umwuma ku bushyuhe bwa 350 ° C, umuvuduko wa 0.01MPa n'umuvuduko wa gaze wa 50-300H-1, hamwe no kubura umwuma muke. reaction yo kuryama Cataliseri yashyutswe kugeza kuri 390 ° C. Nyuma yimyitwarire ya dehidrasi igeze kuringaniza, ibicuruzwa bya N-Ethylene cephalopicone (NVP) bisohoka mumashanyarazi ahamye.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 nkumuti, wasesenguye ibicuruzwa bya N-ethylene cheedone byateguwe nubu buryo, ubara igipimo cyo guhindura NHP, guhitamo NVP, kwinjiza NVP, icyiciro cya gaz icyiciro icyiciro cyicyiciro, icyiciro cya gaz icyiciro cyicyiciro icyiciro, icyiciro cya gaz icyiciro cyari ikizamini cya Chromatografique: Detector ya TCD, inkingi yicyuma idafite inkingi, poly acetike glycol tannite yagutse ikemura 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%.
