Teb tiav: Thaum toluene (methyl benzene) yog oxidized nrog alkaline potassium permanganate tov, benzoic acid khoom tau.
Cov khoom yog dab tsi thaum toluene reacts nrog KMnO4?
Toluene ntawm cov tshuaj tiv thaiv nrog alkaline potassium permanganate cov ntaub ntawv potassium ntsev ntawm benzoic acid.
Thaum toluene raug kho nrog dab tsi tsim?
Benzaldehyde rau ib -Hydroxyphenylacetic acid
YYuav ua li cas thaum toluene oxidized?
tshuaj muaj zog
Ib qho tseem ceeb, methyl sab saw hauv toluene yog raug rau oxidation. Toluene reacts nrog poov tshuaj permanganate kom tawm los benzoic acid, thiab nrog chromyl chloride los tawm benzaldehyde (Étard cov tshuaj tiv thaiv) … Cov tshuaj tiv thaiv yuav tsum muaj lub siab ntawm hydrogen thiab catalyst.
Yuav ua li cas thaum toluene raug kho nrog KMnO4 nyob rau hauv muaj h2so4?
Teb: Cov khoom tau txais yuav benzoic acid. Kev piav qhia: Toluene thaum kho nrog poov tshuaj permanganate hauv cov kua qaub nruab nrab mus hauv qab oxidation recation.
Pom zoo:
Dab tsi yog dab tsi raug kaw?
Deadlocked: Dab ntxwg nyoog. Deadlocked yog qhov nyuaj tshaj plaws los qhib rau ib qho laj thawj: nws nyuaj. Los ntawm ob qho tib si kev taw qhia kev taw qhia thiab ib qho kev cim cim, nws nyuaj rau ob qho tib si spectrums . Puas yog Deadlocked dab insane?
Tus neeg raug foob raug foob yog dab tsi?
Ib tug neeg raug foob, nyob rau hauv rooj plaub txhaum cai, yog lwm tus neeg uas tau raug foob los ntawm Lub Xeev lossis Tsoomfwv hauv koj rooj plaub. Feem ntau tus kws lij choj raug foob raug foob tib yam li koj. Koj tuaj yeem raug them tus nqi ntau dua lossis tsawg dua li koj tus neeg raug foob .
Kev sib txuas lus raug cai thiab tsis raug cai yog dab tsi?
kev sib txuas lus raug txhais tau hais tias yog kev sib txuas lus uas tshwm sim los ntawm txoj hauv kev / txoj hauv kev thiab cov channel. Ntawm qhov tod tes, kev sib txuas lus tsis raws cai txhais tau tias yog kev sib txuas lus uas tshwm sim tsis raws cai ntawm ob lossis ntau tus neeg .
Vim li cas toluene tsis hnov mob nrog bromine?
Benzene thiab toluene tsis hnov mob nrog bromine hauv qhov tsis muaj catalyst Phenol yog ntau reactive vim muaj ib tug electron pub hydroxyl pab pawg neeg thiab reacts nrog bromine los ntawm ib tug hloov. Cov tshuaj tiv thaiv tsim hydrogen bromide hydrogen bromide Hydrogen bromide(HBr) Hydrobromic acid, ib qho kev daws ntawm hydrogen bromide hauv dej.
Thaum dej phwj kho biogases raug tsim tawm uas suav nrog?
Biogas yog tsim los ntawm methane (50-70%), carbon dioxide (30-40%) thiab hydrogen sulphide. Txawm li cas los xij cov kab ntawm nitrogen, hydrogen thiab oxygen arc kuj pom . Qhov twg yog tsim thaum kho dej phwj? Methane, Hydrogen sulfide, Carbon dioxide, thiab Hydrogen:
