This paper introduces both the nature of chlorine dioxide and the main method of production containing electrolysis, oxidation, reduction and process of producing stable chlorine dioxide.

This paper uses oxidation reduction potential method to determine oil enrichment area and performs a pilot test in Yushulin Oil Field in the peripheral part of Daqing.

And it is considered that the reduction-oxidation method would be the optimum method for realizing in industry direct hydroxylation of benzene to phenol.
