Đáp án và Giải thích các bước giải:

$CH_3HCOONa+NaOH\xrightarrow{CaO,\ t^o} CH_4+Na_2CO_3$

$A:\ CH_4$

$2CH_4\xrightarrow[lln]{150^oC}C_2H_2+3H_2$

$B:\ C_2H_2$

$C_2H_2+H_2\xrightarrow{xt,\ t^o,\ Pd}C_2H_4$

$C:\ C_2H_4$

$C_2H_4+H_2O\xrightarrow{xt,\ H_2SO_4}C_2H_5OH$

$D:\ C_2H_5OH$

$C_2H_5OH+O_2\xrightarrow{\rm men\ giấm}CH_3COOH+CO_2$

$E:\ CH_3COOH$

$2CH_3COOH + CaCO_3 → (CH_3COO)_2Ca + CO_2 + H_2O$

$(CH_3COO)_2Ca\xrightarrow{t^o}CH_3-C(=O)CH_3+CaCO_3$

$(CH_3COO)_2Ca + H_2SO_4 → 2CH_3COOH + CaSO_4$

*PTHH chi tiết:

CH3COONa + NaOH $\xrightarrow[t^o]{CaO}$ CH4 (A) + Na2CO3

2CH4 (A) $\xrightarrow[l.l.n]{1500^oC}$ C2H2 (B) + 3H2

C2H2 (B) + H2 $\xrightarrow[t^o]{Pd/PbCO3}$ C2H4 (C)

C2H4 (C) + H2O $\xrightarrow{axit}$ C2H5OH (D)

C2H5OH (D) + O2 $\xrightarrow{mengiam}$ CH3COOH (E) + H2O

2CH3COOH (E) + Ca(OH)2 → (CH3COO)2Ca + 2H2O

(CH3COO)2Ca $\xrightarrow{t^o}$ CaCO3 + CH3COCH3

(CH3COO)2Ca + H2SO4 → 2CH3COOH + CaSO4
