Lub synthesis ntawm acetyl ferrocene yog raws li nram no: Them ib 25mL puag ncig hauv qab khob nrog ferrocene (1g) thiab acetic anhydride (3.3mL). Ntxiv phosphoric acid (0.7mL, 85%) thiab kub cov tshuaj tiv thaiv sib tov rau ntawm qhov kub dej da dej rau 20 feeb nrog stirring. Ncuav qhov sib tov kub rau hauv dej khov (27g).
Hais txog qhov no, ferrocene siv rau dab tsi?
Ferrocene thiab nws cov derivatives yog antiknock agents siv hauv roj rau roj cav; lawv muaj kev nyab xeeb dua li tetraethyllead, yav tas los siv . Petrol additive daws muaj ferrocene tuaj yeem muab ntxiv rau cov roj av tsis muaj roj kom nws siv tau rau hauv cov tsheb vintage tsim los khiav ntawm cov roj lead.
Ib yam li ntawd, tus qauv ntawm ferrocene yog dab tsi? C10H10 Fe
Ntxiv mus, cov tshuaj tiv thaiv dab tsi tuaj yeem ua rau ferrocene?
Vim lub aromatic cim ntawm cyclopentadienyl ligands, ferrocene (1) tuaj yeem raug Friedel-Crafts acylation tshuaj tiv thaiv ua form acetylferrocene (2). Ferrocene tuaj yeem kuj nyob rau hauv ib ligand exchange tshuaj tiv thaiv nruab nrab ntawm ib qho ntawm cyclopentadienyl rings thiab benzene los ua complex 3.
Vim li cas Ferrocenium xiav?
Hlau (III) chloride yog ib qho tsis muaj zog oxidant, thiab cov hlau nyob rau hauv lub complex tuaj yeem tau txais ib qho hluav taws xob kom txo tau mus rau lub xeev oxidation +2. Kev hloov ntawm ib qho hluav taws xob los ntawm ferrocene mus rau hlau chloride complex oxidises ferrocene rau ferrocenium . Cov ion no muaj tus yam ntxwv xiav xim.

Dab tsi yog qhov cuab yeej tsim nyog ua ntej kev tshawb xav ntawm tes yuav tsim tau?
Lub microscope yog tsim nyog ua ntej qhov kev xav ntawm tes yuav tsim. Peb tus kws tshawb fawb twg tau txais qhab nia rau cov pov thawj ncaj qha ua rau txoj kev xav ntawm tes? Matthias Schleiden, Theodor Schwann, thiab Rudolph Virchow peb yog txhua tus kws tshawb fawb uas tau pab txhawb txoj kev xav ntawm tes
Dab tsi yog qhov txawv ntawm kev xaiv khoom tsim thiab kev tsim noob caj noob ces?
Artificial xaiv xaiv rau cov yam ntxwv uas twb muaj nyob rau hauv ib hom, whereas genetic engineering tsim cov yam ntxwv tshiab. Hauv kev xaiv dag, cov kws tshawb fawb yug tsuas yog cov tib neeg uas xav tau qhov zoo. Los ntawm kev xaiv kev yug me nyuam, cov kws tshawb fawb muaj peev xwm hloov cov cwj pwm hauv cov neeg. Evolution tau tshwm sim
Qhov kev sib npaug twg yog qhov tsim nyog los suav cov cua sov uas tsim los ntawm HCl NaOH cov tshuaj tiv thaiv?
Xam cov naj npawb ntawm moles ntawm lub hauv paus koj ntxiv los txiav txim siab molar tshav kub ntawm qhov nruab nrab, qhia siv qhov sib npaug Δ H = Q ÷ n, qhov twg 'n' yog tus naj npawb ntawm moles. Piv txwv li, xav tias koj ntxiv 25 mL ntawm 1.0 M NaOH rau koj HCl los ua kom muaj cua sov ntawm nruab nrab ntawm 447.78 Joules
Lub chaw tsim hluav taws xob nuclear tsim tau li cas?
Nuclear fission tsim cua sov Reactors siv uranium rau nuclear roj. Cov uranium tau ua tiav rau hauv cov me me ceramic pellets thiab muab tso ua ke rau hauv cov raj hlau kaw hu ua roj rods. Lub tshav kub tsim los ntawm fission hloov cov dej mus rau hauv chav, uas tig lub turbine los tsim hluav taws xob tsis muaj carbon
Vim li cas thiaj nres thiab pib codons tsim nyog rau kev tsim cov protein?
Pib thiab nres codons yog ib qho tseem ceeb vim hais tias lawv qhia lub xov tooj ntawm tes machinery qhov twg yuav pib thiab xaus kev txhais lus, txheej txheem ntawm kev ua cov protein. Qhov pib codon cim qhov chaw ntawm qhov kev txhais lus rau hauv protein ntau pib. Qhov nres codon (los yog termination codon) cim lub vev xaib uas txhais lus xaus
