Claims22
A process for decomposing an organic compound selected from the group consisting of aliphatic hydrocarbons, aromatic hydrocarbons, halogenated aliphatics, halogenated aromatics, aliphatic oxo-compounds, aromatic oxo-compounds, nitrogen-containing aliphatic compounds, nitrogen-containing aromatic compounds, and sulfur-containing compounds comprising:
- (a) putting said organic compound in an acidic solution to form a reaction solution having a pH value of less than 7;
- and
- (b) using an electrolytic system having a working electrode, said working electrode is a graphite-containing electrode, to electrolyze said reaction solution in contact with an oxygen-containing gas which is dioxygen gas or air and at a reductive potential or current.
