Electrochemical behaviour of bisazodye-chrysophenine

The electrochemical behaviour of the bisazodye-chrysophenine has been studied in the pH range 3.0-10.3 at the dropping mercury electrode and at the pyrolytic graphite electrode.On the basis of polarographic, cyclic voltammetric, coulometric and spectral studies it is concluded that unlike bisazobenzene, where a first 4e, 4H+ process gives the bishydrazo derivative, the cleavage of one of the azo group occurs in this dye.This difference in behaviour is explained on the basis of strongly electron donating substituents present in chrisophenine.The products of electroreduction have been separated and identified.
