Nitric Acid → Nitro-p-xylene

Participants

Reaction Steps

A mixture of p-xylene (25 ml), and Fe3+ montmorillonite or Zn2+ montmorillonite (0.5 g) were taken in a 50 ml two-necked round-bottomed flask equipped with Dean-Stark apparatus. Fuming nitric acid (5 ml) was added dropwise into the reaction mixture. The reaction mixture was heated to reflux where upon the required amount of liberated water was collected in the Dean-Stark apparatus which usually takes 1.5 hr. Later on, the catalyst was filtered and the reaction mixture was concentrated to obtain the nitro p-xylene.
