Physical–chemical Analysis and Kinetics of the Magnetic Biocatalyst for 2,3,6,-Trimethylphenol Oxidation

In the paper, the synthesis of the magnetic biocatalyst based on immobilized peroxidase is described. This catalyst was tested in the reaction of 2,3,6,-trimethylphenol oxidation with the help of hydrogen peroxide to 2,3,5-trimethylhydrochinone (vitamin E intermediate). In the work, the method for magnetic nanoparticle synthesis was chosen. To characterize the synthesized biocatalyst physical–chemical analysis was carried out: transmission electron microscopy, FTIR spectroscopy, the study of magnetic characteristics with vibration magnetometer, X-ray photoelectron spectroscopy, low-temperature nitrogen adsorption. The optimum conditions for the process of 2,3,6,-trimethylphenol oxidation in the presence of magnetic biocatalyst (the substrate initial concentration, temperature, pH).
