Phosphotungustic acid catalyzed oxidation of aliphatic primary alcohols (methanol and ethanol) into aldehydes in aqueous acetic acid medium with N-chloroisonicotinamide was reported. Keggin anion tungustic acid was able to form ternary complex with oxidant species and substrate in pre-equilibrium state. The order with respect to [substrate] changes from first to zero-order. The reaction is first-order in [NCIN] and less than unit order in acid. Acetic acid accelerates the reaction rate. The added products isonicotinamide and salt do not significantly affect the reaction rate, a suitable mechanisms proposed with rate law, supported by involved reaction constants and activation parameters.
