Participants

Reaction Steps

Ferric chloride hexahydrate 5.4 g (0.02 mole) was dissolved in 20 ml 0.1 M HCl at room temperature. The tetraaniline in the leucoemeraldine oxidation state from Example 3 above 3.66 g (0.01 mole) was suspended in 250 ml 0.1 M HCl solution with magnetic stirring for 0.5 hours at room temperature. The ferric chloride solution was added very quickly (within 1~2 seconds) to the tetraaniline suspension with strong stirring. The suspension was then stirred magnetically for 2 hours. The reaction mixture was filtered, washed and neutralized following the general procedure described herein.
