Convert ethane to acetic acid.
Advertisements
उत्तर
Ethane is first converted (oxidised) into ethyl alcohol, and then ethyl alcohol is oxidised into acetic acid in the presence of platinum at 300°C.
\[\ce{\underset{Ethane}{2C2H6} + O2 ->[475K Cu tube][120atm]\underset{Ethyl alcohol}{2C2H5OH}->[Pt][300^\circ C]\underset{Acetic acid}{CH3COOH} + H2O}\]
