Question

Hoàn thành chuỗi phản ứng sau:

saccarozo -> glucozo -> rượu etylic -> axit axetic -> etyl axetat -> rượu etylic  -> natri axetat

(Mn ghi điều kiện phản ứng luôn giúp em ạ.)

 

Answer 1

CaO + 3C => CaC2 + CO

CaC2 + 2H2O => Ca(OH)2 + C2H2 (axetilen)

3C2H2 => (cacbon hoạt tính, 600^oC) C6H6

C6H6 + Br2 => HBr + C6H5Br (brom benzen)

C2H2 + H2 => (t^o,Pd) C2H4

C2H4 + H2O => (140^oC, H2SO4đ) C2H5OH (rượu etylic)

C2H5OH + O2 => (men giấm) H2O + CH3COOH (axit axetic)

CH3COOH + C2H5OH => (t^o,H2SO4đ, pứ hai chiều) H2O + CH3COOC2H5 (etyl axetat)

n -(CH2-CH2)- => (t^o,xt,P) -(CH2-CH2)-n

Answer 2

\(C_{12}H_{22}O_{11}+H_2O\underrightarrow{t^0}C_6H_{12}O_6+C_6H_{12}O_6\)

\(C_6H_{12}O_6\underrightarrow{men.rượu}2C_2H_5OH+2CO_2\)

\(C_2H_5OH+O_2\underrightarrow{men.giấm}CH_3COOH+H_2O\)

\(CH_3COOH+C_2H_5OH⇌CH_3COOC_3H_5+H_2O\)

\(CH_3COOC_3H_5+H_2O⇌C_2H_5OH+CH_3COOH\)

\(C_2H_5OH+Na\rightarrow C_2H_5ONa+2H_2\uparrow\)

Answer 3

\(C_{12}H_{22}O_{11}+H_2O\underrightarrow{t^o}C_6H_{12}O_6+C_6H_{12}O_6\\ C_6H_{12}O_6\underrightarrow{men.rượu}2C_2H_5OH+2CO_2\uparrow\\ C_2H_5OH+O_2\underrightarrow{men.giấm}CH_3COOH+H_2O\\ CH_3COOH+C_2H_5OH\xrightarrow[H_2SO_{4\left(đ\right)}]{t^o}CH_3COOC_2H_5+H_2O\\ CH_3COOC_2H_5+NaOH\rightarrow CH_3COONa+C_2H_5OH\)
