And the article contained the following:
Urea-formaldehyde (UF) resin residues and the related product wastes as organic hazardous wastes are difficult to be biodegraded or recycled. In this research, a hydrothermal oxidation method using hydrogen peroxide (H2O2) solution has been developed for the degradation and recycling of UF resin residues. The effects of solution concentration, temperature, and time on the degradation efficiency and products of UF resin residues were studied. Under optimal conditions, i.e., 140°C and 5 wt% H2O2 solution, over 75% of UF resin residues was degraded after 3 h. The degradation efficiency is much higher than that of the traditional hydrothermal treatment or acid hydrolysis method. In addition, results from Fourier transform IR spectroscopy (FTIR), gas chromatog.-mass spectroscopy (GC-MS), NMR spectroscopy (NMR), and X-ray diffraction (XRD) confirmed that H2O2 solution degrades UF resin residues to low mol. compounds, such as alcs., methylal, and amides. This research provides a novel and high-efficient hydrothermal oxidization process for the degradation of UF resin residues, which might be a promising environmentally friendly and low-cost method for the disposal and recycling of industrial UF resin residues. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Quality Control of 2,4-Di-tert-butylphenol
