Cov tshuaj tiv thaiv Wurtz, muaj npe tom qab Charles Adolphe Wurtz, yog qhov sib txuas cov tshuaj tiv thaiv hauv cov organic chemistry, organometallic chemistry thiab tsis ntev los no inorganic lub ntsiab-polymers, uas yog ob qho alkyl halides reacted nrog sodium hlau hauv qhuav ether. tshuaj tsim kom muaj alkane siab dua.
Yuav ua li cas cov tshuaj reagent siv yog?
A reagent /riˈeɪdʒənt/ yog khoom lossis cov khoom sib txuas ntxiv rau lub kaw lus kom ua rau muaj tshuaj lom neeg, lossis ntxiv rau kev sim yog tias muaj cov tshuaj tiv thaiv tshwm sim. Cov ntsiab lus reactant thiab reagent feem ntau yog siv sib hloov-txawm li cas los xij, ib qho reactant tshwj xeeb tshaj yog cov khoom siv hauv cov tshuaj tiv thaiv tshuaj.
Vim li cas NA siv hauv Wurtz cov tshuaj tiv thaiv?
In Wurtz cov tshuaj tiv thaiv sodium hlau yog siv uas yog reactive heev. Yog li kev xaiv ntawm cov kuab tshuaj yog ua nyob rau hauv xws li ib txoj kev uas cov sodium hlau tsis hnov mob nrog cov kuab tshuaj. … Txij li thaum qhuav ether yog ib qho zoo uas tsis yog-polar, aprotic hnyav, yog li nws yog siv rau hauv cov tshuaj tiv thaiv Wurtz.
Dab tsi yog cov catalyst siv hauv Wurtz cov tshuaj tiv thaiv?
Dry ether yog siv hauv Wurtz tshuaj tiv thaiv.
Wurtz tshuaj tiv thaiv piv txwv yog dab tsi?
Wurtz Reaction Equation
Raws li piv txwv, peb tuaj yeem tau txais ethane los ntawm kev ua haujlwm methyl bromide nrog sodium nyob rau hauv lub xub ntiag ntawm anhydrous ether los yog tetrahydrofuran. Ntawm no, ib qho loj alkane molecule yog tsim los ntawm kev koom ua ke ob qho tib si ntawm alkyl halide thiab tshem tawm cov halogen atoms nyob rau hauv daim ntawv ntawm sodium halide.
