Thaum ferrocene yog acetylated, nws txhais tau tias uas ib pab pawg acetate tau ntxiv rau ib qho ntawm cyclopentadienyl rings … Txhawm rau ntxiv ib pawg acetyl rau ferrocene txhua yam peb yuav tsum tau ua. yog react nws nrog acetic anhydride (qhov chaw ntawm acetyl pawg) thiab ib co phosphoric acid.
Dab tsi yog qhov hnyav hauv acetylation ntawm ferrocene?
Lub Friedel-Crafts acylation cov tshuaj tiv thaiv ntawm ferrocene koom nrog qhov sib ntxiv ntawm acylium cation rau ib qho ntawm cov pa roj carbon atoms ntawm lub nplhaib, ua raws li kev poob ntawm proton (kom hnyav). Lub acylium cation yog tsim los ntawm acetic anhydride, uas kuj yog ib qho hnyav rau cov tshuaj tiv thaiv no.
ferrocene synthesized li cas?
Industrially, ferrocene yog synthesized los ntawm cov tshuaj tiv thaiv ntawm hlau (II) ethoxide nrog cyclopentadiene; Cov hlau (II) ethoxide xav tau yog tsim los ntawm electrochemical oxidation ntawm hlau hlau hauv anhydrous ethanol.
Koj txhais li cas los ntawm cov tshuaj tiv thaiv acetylation?
Acetylation yog cov tshuaj tiv thaiv tshuaj uas muaj hydrogen atom hloov pauv rau pawg acetyl (CH3C=O. hauv ib qho kev sib xyaw. … Thaum cov hydrogen atom uas yog ib pawg cawv hloov nrog ib pawg acetyl hauv cov tshuaj tiv thaiv acetylation, ib qho ester yog tsim los ntawm cov khoom.
Puas Acetylferrocene puas txaus ntshai?
Kev phom sij! Yuav tuag yog nqos. Toxic yog absorbed los ntawm daim tawv nqaij. Tej zaum yuav ua rau qhov muag, tawv nqaij, thiab ua pa ua pa.
