Question

BT: Viết PTHH thực hiện dãy chuyển hóa sau:

a, Glucozơ → rượu etylic → axit axetic → etylaxetat.

b, Saccarozơ → Glucozơ → rượu etylic → axit axetic → natri axetat.

c, Glucozơ → rượu etylic → axit axetic → etyl axetat → natri axetat.

d, C₂H₅OH → CH₃COOH → CH₃COOC₂H₅ → (CH₃COO)₂Ca → CH₃COOH

 

 

Answer 1

\(a) C_6H_{12}O_6 \xrightarrow{t^o,xt} 2CO_2 + 2C_2H_5OH\\ C_2H_5OH + O_2 \xrightarrow{men\ giấm} CH_3COOH + H_2O\\ CH_3COOH + C_2H_5OH \to CH_3COOC_2H_5 + H_2O\\ b) C_{12}H_{22}O_{11} + H_2O \xrightarrow{H^+}C_6H_{12}O_6 + C_6H_{12}O_6\\ C_6H_{12}O_6 \xrightarrow{t^o,xt} 2CO_2 + 2C_2H_5OH\\C_2H_5OH + O_2 \xrightarrow{men\ giấm} CH_3COOH + H_2O\\ CH_3COOH + NaOH \to CH_3COONa + H_2O\\ c) CH_3COOC_2H_5 + NaOH \to CH_3COONa + C_2H_5OH\\ d) 2CH_3COOC_2H_5 + Ca(OH)_2 \to (CH_3COO)_2Ca + 2C_2H_5OH\)

\((CH_3COO)_2Ca + H_2SO_4 \to CaSO_4 + 2CH_3COOH\)
