Tungstate ion was heterogenized on the silica-coated magnetite nanoparticles and applied for the selective oxidation of anilines to nitroso arenes—with hydrogen peroxide/urea as oxidant in dimethyl carbonate as solvent—in moderate–good yields (40–96%). The catalyst was characterized using different techniques including Fourier-transform infrared spectroscopy, X-ray powder diffraction, vibrating sample magnetometry, scanning electron microscopy, energy dispersive X-ray and inductively coupled plasma atomic emission spectroscopy (ICP-AES). The catalyst was easily recovered using an external magnet and reused for six times.

Paragraph 0062-0069, (2017/04/04)
The present invention refers to 4-manufacturing method relates to with child Neel phosphorus nitro, more particularly sodium urate (sodium urate), or their mixtures (potassium urate) potassium urate a urate in response to 40 to 120 °C nitrobenzene mono salt 4-nitro by the inclusion of step of manufacturing a nitrosoaniline, reactants use urate forming silicide film having excellent thermal stability the carbonate and ammonia and the like of a high yield conversion and without the formation of a leaving component 4-nitrosoaniline nitro method relates to manufacturing.
