The oxidation of p-toluidine in acetonitrile by hydrogen peroxide is a very slow reaction which produces 4,4'-dimethylazoxybenzene as the product. The presence of functionalized multiwalled carbon nanotubes (CNT) in the above reaction produces 4,4'-dimethylazobenzene. The reactions have been followed by GC/MS, which show the following mass nos.: 226,92 (without CNT) and 210,120,92,28 (with CNT). UV-VIS absorption spectroscopy shows maximum corresponding to 4,4'-dimethylazobenzene at 444 nm. The rate of formation of 4,4'-dimethylazobenzene has been determined as 0.0093 s -1.
