1. \(\left(C_6H_{10}O_5\right)_n+nH_2O\underrightarrow{t^o,H^+}nC_6H_{12}O_6\)

\(C_6H_{12}O_6\underrightarrow{^{lenmenruou}}2C_2H_5OH+2CO_2\)

\(C_2H_5OH+O_2\underrightarrow{^{mengiam}}CH_3COOH+H_2O\)

\(CH_3COOH+C_2H_5OH⇌CH_3COOC_2H_5+H_2O\) (xt: H₂SO₄, t^o)

2. \(\left(C_6H_{10}O_5\right)_n+6nO_2\underrightarrow{t^o}6nCO_2+5nH_2O\)

\(C_6H_{12}O_6+6O_2\underrightarrow{t^o}6CO_2+6H_2O\)

3. \(C_2H_5OH+3O_2\underrightarrow{t^o}2CO_2+3H_2O\)

\(2CH_3COOH+Na_2CO_3\rightarrow2CH_3COONa+CO_2+H_2O\)

4. \(CH_3COOC_2H_5+5O_2\underrightarrow{t^o}4CO_2+4H_2O\)
