The oxidation of isopropylbenzene in the presence of copper nanopowders

The oxidation of isopropylbenzene with oxygen in the presence of copper nanopowders prepared under various wireelectrical explosion conditions was studied. The oxidative conversion of isopropylbenzene was observed only for nanopowders with a linear function of oxygen absorption. Holding copper nanopowders in a vacuum stimulated their initiating activity. A lower initial temperature of the oxidation of nanopowders in air corresponded to a higher rate of oxygen absorption by isopropylbenzene. The amount of absorbed oxygen was not equivalent to the conversion of isopropylbenzene.
