Activated carbon experimental conditions and process

In the current work, under mild reaction conditions, in the presence of oxygen, activated carbon is used as a metal-free catalyst for the oxidation of cyclohexane without epoxidation to KA oil. The reaction parameters were optimized and the catalytic efficiency was found in terms of productivity. The convenience of preparation, sufficient activity, low cost, recyclability, impermeability and environmental protection make activated carbon a useful catalyst for the solvent-free oxidation of cyclohexane.activated carbon australia 

The surface morphology of activated carbon was studied by scanning electron microscope. The elemental composition of activated carbon was recorded by using energy dispersive X-ray spectroscopy. X-ray analysis was performed by X-ray diffractometer. The functional groups on the surface of activated carbon were examined by Fourier transform infrared spectrometer. The weight loss percentage of heat was carried out by a TGA thermal analyzer in a temperature range of 0/1000 ° C at a rate of 10 ° C / min under N 2 flow. The surface area of activated carbon was measured using a chromium surface area analyzer. Ningxia activated carbon manufacturer

Load cyclohexane (12.5 mL) and activated carbon (0.4 g) into a self-built double-wall three-port batch reactor. The mixture was stirred at 75 ° C for 14 hours in the presence of molecular oxygen (40 mL / min). In the same set of reaction parameters, the reaction was also carried out in the presence of basic NaOH: 0.2 mmole. The conversion of cyclohexane to KA oil was analyzed by gas chromatography, using a cross-linked methylsiloxane capillary column (30 μm, inner diameter 0.32 mm, mm film thickness), connected to a flame ionization detector (FID).
