Degradation of PVA wastewater by CuxMnxFe3-2xO4/MWCNT catalyst was written by Zhang, Yue;Zhu, Gaofeng;Ge, Mingqiao. And the article was included in Journal of Materials Science: Materials in Electronics in 2021.Synthetic Route of C20H26O4 This article mentions the following:
CuxMnxFe3-2xO4/MWCNT nanocomposites were prepared by co-precipitation method. The structure, morphol., and surface properties of the samples were characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM), Energy dispersive spectrometer (EDS), Fourier transform IR spectrometer (FTIR), N2 phys. adsorption instrument, and X-ray photoelectron spectrometer (XPS). The successful loading of metal oxides on MWCNTs increased the catalytic activity of nanocomposites. In addition, CuxMnxFe3-2xO4/MWCNTs were used as catalyst for the degradation of PVA wastewater by catalytic wet air oxidation Under the degradation conditions, pH was 2.5, catalyst dosage was1.5 g/L, reaction temperature was 275 °C, oxygen pressure was 1.0MP, the PVA degradation rate was 99.94%, the viscosity average mol. weight was decreased by 99.36%, and the degradation products were small mols. such as aldehydes, phenols, and acids, which basically confirmed the degradation of PVA wastewater. The degradation principle and kinetics were analyzed. The catalyst was washed and recovered and can maintain good catalytic capacity after four times of repeated use. In the experiment, the researchers used many compounds, for example, Dicyclohexyl phthalate (cas: 84-61-7Synthetic Route of C20H26O4).
Dicyclohexyl phthalate (cas: 84-61-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Synthetic Route of C20H26O4
