Qib siab cov khoom siv vanadium pentoxide flake

Thaum tsis muaj oxidant, kwv yees li 80% ntawm cov vanadium nyob rau hauv pob zeb thee tuaj yeem yog cov sulfuric cov roj acid ntawm 8: 1, thiab lub ore particle loj yog} mesh mesh Cov. Tus huvVanadium pentoxideKev daws teeb meem tuaj yeem tau los ntawm kev rho tawm ntawm sulfonated daws ntawm p204 thiab tom qab ntawd rov qab muaj kev coj dawb huv ntawm ntau dua 98% tuaj yeem tau los ntawm ammonia nag lossis daus.

1.Nyob rau hauv chav tsev kub, cyclohexene tsuas yog undergoes allyl oxidation nyob rau hauv lub catalytic system los ua cyclohexelenone. Hom tshuaj muaj zog muaj cov kev ua ub ua no thiab kev xaiv cov kev ua ub no ntawm cov allyl ketone oxidation, thiab acetone yog cov kuab tshuaj rau cov tshuaj no. Nyob rau hauv cov xwm txheej ntawm cov ntim sib piv ntawm acetone rau cyclohexene yog 4, qhov sib piv ntawmVanadium pentoxiderau cyclohexene yog 1:40, tus nqi hniav tshuaj hniav ntawm hydrogen peroxide rau cyclohexide yog 3%, thiab kev xaiv ntawm cyclohexenone tuaj yeem ncav cuag 85 % .Qhov oxidative roasting cov txheej txheem muaj qhov cuam tshuam tseem ceeb ntawm kev rho tawm ntawm vanadium, thaum cov txheej txheem dej immersion muaj cov nyhuv me me. Vanadium tau hloov mus rau hauv soduble sodium vanadate thiab insoluble calcium calcium vanadate los ntawm oxidative ci. Thaum lub sij hawm dej raus dej raus, sodium vanadate dissolves hauv dej; Calcumium vanadate reacts nrog sodium phosphate lossis sodium sodium vanadate, uas tuaj yeem tshem tawm cov khoom seem uas muaj kev cuam tshuam silicon thiab phosphorus nyob rau hauv txoj kev daws teeb meem.
