Oxidation of 2,3,6-trimethylphenol to 2,3,5-trimethyl-1,4-benzoquinon over binary xerogels TiO2-SiO2 in the three-phase system

摘要

The technique of synthesis of 2,3,5-trimethyl-1,4-benzoquinon via catalytic oxidation of 2,3,6-trimethylphenol in H2O2-H2O-PhCH3 system with vibrational stirring is developed. Xerogels TiO2 and TiO2-SiO2 were used as catalysts in the process. The effect of physicochemical properties of xerogels on the course and characteristics of oxidation is studied.
