Oxidation ntawm naphthalene ntawm Co-Mo−O, NiMoO4 thiab Mg-Mo−O catalysts muab phthalic anhydride, nws cov txiaj ntsig siab tshaj plaws yog kwv yees li 40% ntawm nickel molybdate. Ntawm bismuth molybdates thiab Sn-Sb-O system, naphthalene feem ntau yog oxidized rau carbon oxides.
Dab tsi yog cov khoom oxidation ntawm naphthalene?
Cov tshuaj tiv thaiv thawj zaug hauv oxidation ntawm naphthalene los ntawm Pseudomonas sp. NCIB 9816 involve the enzymatic incorporation of one molecule of oxygen into the aromatic nucleus to form (+)-cis-(1R, 2S)-dihydroxy-1, 2-dihydronaphthalene.
Vim li cas naphthalene reactive rau KMnO4?
oxidises ob daim ntawv cog lus. Kev tsim ntawm dicarboxylic acid tshwm sim thaum lub sij hawm oxidation ntawm naphthalene nrog KMnO4 nyob rau hauv acidic mob. thiab ob pawg carboxylic acid tau txuas nrog. Cov compound tsim yog hu ua Phthalic acid.
YKoj ua phthalic acid los ntawm naphthalene li cas?
Production. Phthalic acid yog tsim los ntawm cov catalytic oxidation ntawm naphthalene lossis ortho-xylene ncaj qha rau phthalic anhydride thiab tom qab hydrolysis ntawm anhydride. Phthalic acid yog thawj zaug tau los ntawm Fabkis chemist Auguste Laurent xyoo 1836 los ntawm oxidizing naphthalene tetrachloride.
Nws yog oxidized nyob rau hauv lub xub ntiag ntawm v2o2 kom tau phthalic anhydride?
V2O5/TiO2 yog ib qho tseem ceeb catalyst rau ib nrab oxidation ntawm o-xylene rau phthalic anhydride. Qhov kev xaiv oxidation no heevtxheej txheem exothermic thiab cov txiaj ntsig ntawm cov khoom muaj zog nyob ntawm kev ruaj ntseg thiab kev ua haujlwm ntawm catalyst.
