$C_6H_{12}O_6 \xrightarrow{t^o,men\ rượu} 2CO_2 + 2C_2H_5OH$
$C_2H_5OH \xrightarrow{t^o,H_2SO_4} C_2H_4 + H_2O$
$C_2H_4 + H_2O \xrightarrow{t^o,H^+} C_2H_5OH$
$C_2H_5OH + HBr \to C_2H_5Br + H_2O$
$C_2H_5OH + CuO \xrightarrow{t^o} Cu + CH_3-CHO + H_2O$
$C_2H_5OH + O_2 \xrightarrow{men\ giấm} CH_3COOH + H_2O$
$CH_3COOH + C_2H_5OH \buildrel{{H_2SO_4}}\over\rightleftharpoons CH_3COOC_2H_5 + H_2O$
