Only primary and secondary alcohols can be oxidised. This usally uses potassium dichromate as an oxidising agent.
Primary alcohols can be oxidised, firstly, to aldehydes.
CH3CH2CHOH + (O) > CH3CH2CH=O + H20
They must be distilled out of the colution, to avoud further oxidation.
Carboxylic acids are made by reflux of primary alcohols (aldehydes.)
CH3CH2CHOH +2(O) > CH3CH2COOH +H20
Secondary alcohols are oxidised to make ketones.
CH3CH(OH)CH3 +(O) > CH3C=OCH2CH3 +H20
Tertairy alcohols are resistant to oxidation.
