Dab tsi yog kev siv zirconium tetrachloride?
Zirconium tetrachloride (ZrCl4)muaj ntau yam kev siv, suav nrog:
Kev npaj ntawm Zirconia: Zirconia tetrachloride tuaj yeem siv los npaj zirconia (ZrO2), uas yog ib qho tseem ceeb ntawm cov qauv thiab cov khoom siv nrog cov khoom siv zoo heev thiab tshuaj lom neeg xws li kub tsis kam, hnav tsis kam, thiab corrosion kuj. Zirconia yog dav siv nyob rau hauv high-tech teb xws li cov ntaub ntawv refractory, ceramic pigments, hluav taws xob ceramics, functional ceramics, thiab structural ceramics.
Kev npaj ntawm sponge zirconium: Sponge zirconium yog ib qho ntxeem tau hlau zirconium nrog siab hardness, siab melting point, thiab superior corrosion kuj, uas yuav siv tau nyob rau hauv high-tech industries xws li nuclear zog, tub rog, aerospace, thiab lwm yam.
Organic synthesis catalyst: Zirconium tetrachloride, raws li lub zog Lewis acid, tuaj yeem siv los ua cov khoom siv rau cov organic synthesis xws li roj av tawg, alkane isomerization, thiab butadiene npaj.
Textile ua tus neeg saib xyuas: Zirconium tetrachloride tuaj yeem siv los ua hluav taws kub thiab dej tsis zoo rau textiles los txhim kho lawv cov kev tiv thaiv
Pigments thiab tanning: Zirconium tetrachloride kuj tseem siv rau hauv kev tsim cov xim thiab cov txheej txheem tanning ntawm tawv
Analytical reagent: Hauv chav kuaj, zirconium tetrachloride tuaj yeem siv los ua kev tshuaj ntsuam reagent
Cov ntaub ntawv nyoos rau lwm cov zirconium tebchaw: Zirconium tetrachloride kuj tseem siv tau los tsim lwm cov zirconium hlau sib txuas, nrog rau tsim cov catalysts, waterproofing agents, tanning agents, analytical reagents, thiab lwm yam khoom, uas yog siv rau hauv kev lag luam xws li electronics, metallurgy. , chemical engineering, textiles, tawv, thiab lwm yam
Dab tsi yog cov yam ntxwv ntawm zirconium tetrachloride ua catalyst?
Zirconium tetrachloride ua catalyst muaj cov yam ntxwv hauv qab no:
Muaj zog acidity: Zirconium tetrachloride yog Lewis acid muaj zog, uas ua rau nws zoo heev nyob rau hauv ntau cov tshuaj tiv thaiv uas yuav tsum tau muaj zog acid catalysis, tshwj xeeb tshaj yog nyob rau hauv cov organic synthesis tshua.
Txhim kho cov tshuaj tiv thaiv kev ua haujlwm thiab kev xaiv: Hauv oligomerization, alkylation, thiab cyclization cov tshuaj tiv thaiv, zirconium tetrachloride tuaj yeem txhim kho cov tshuaj tiv thaiv zoo thiab cov khoom xaiv
Kev siv dav: Zirconium tetrachloride yog dav siv los ua cov khoom siv hauv cov organic synthesis, nrog rau kev ua kom nrawm nrawm, Michael ntxiv, thiab cov tshuaj tiv thaiv oxidation.
Tus nqi pheej yig, tsis muaj tshuaj lom, thiab ruaj khov: Zirconium tetrachloride yog suav tias yog tus nqi pheej yig, tsis muaj tshuaj lom, ruaj khov, ntsuab, thiab muaj txiaj ntsig catalyst.
Yooj yim rau lis thiab khaws cia: Txawm hais tias zirconium tetrachloride yog qhov ua rau deliquescence, nws tuaj yeem ruaj ntseg khaws cia hauv qhov tsim nyog (hauv lub thawv qhuav, kaw)
Yooj yim rau hydrolyze: Zirconium tetrachloride yog qhov yooj yim rau kev nqus dej noo thiab hygroscopicity, thiab tuaj yeem hydrolyze rau hauv hydrogen chloride thiab zirconium oxychloride hauv cov huab cua ntub lossis aqueous daws. Qhov no yuav tsum tau muab sau tshwj xeeb thaum siv los ua catalyst
Sublimation yam ntxwv: Zirconium tetrachloride sublimates ntawm 331 ℃, uas yuav siv tau nyob rau hauv nws cov txheej txheem purification los ntawm re sublimating nyob rau hauv ib tug hydrogen kwj kom tshem tawm impurities
Hauv cov ntsiab lus, zirconium tetrachloride yog dav siv los ua cov khoom siv hauv cov organic synthesis vim nws cov acidity muaj zog, txhim kho cov tshuaj tiv thaiv thiab kev xaiv, ntau yam kev siv, thiab tus nqi qis thiab toxicity. Lub caij no, nws yooj yim hydrolysis thiab sublimation yam ntxwv kuj yuav tsum tau coj mus rau hauv tus account thaum lub sij hawm ua hauj lwm txheej txheem.
