Investigation into experimental conditions and factors for cyclohexane oxidation with VO(acac)2

Abstract

The catalytic activity of VO(acac) 2 for the cyclohexane(Cy) oxidation was studied. The effects of various parameters, such as the amounts of H 2 O 2 , HNO 3 , H 2 O and Cy were investigated. The highest total turnover number(TON) is 234, which can be increased to 353, 342 and 403, respectively with the adding of o-phthalic, m-phthalic or p-phthalic acid. A reaction mechanism was also supposed primarily.

Exothermic laws applicable to the degradation of o-phenylenediamine in wastewater via a Fe3+/H2O2 homogeneous quasi-Fenton system

“…In addition, the entire process is simple and is oen used to treat wastewater containing undegradable organic matter. [4][5][6] However, conventional homogeneous Fenton systems require pH levels to be controlled below 3; thus, high volumes of acid are required for the acidication as a part of the wastewater treatment. Therefore, aer degradation is complete, correspondingly high quantities of alkalis are required to neutralize the treated wastewater, which greatly increases the cost of the process.…”
