The concept and practical realisation of corona discharge reactor for destruction isopropyl alcohol were presented in this paper. A new electrode systems made in our laboratory was applied for oxidate destruction of isopropyl alcohol. The experimental results shown high efficiency of the reactor in destruction of isopropyl alcohol. The degree of destruction achieved the value of 95%. If has been found that only carbon dioxide and water vapour were the products of the reaction. The results of measurements indicated also high efficiency of electrode systems of corona discharge reactor which was used in the experiments. They showed also that a very important factor is the shape of reaction zone.
