Abstract
A method of oxidizing trimethylphenol (TMP) to trimethylbenzoquinone (TMBQ) by various molecular sieves containing various transition metals. In this method, TMP, a molecular sieve containing a transition metal in its framework, an oxidant and a solvent are mixed together to form a reaction system. The reaction system reacting at a temperature of about room temperature to 150° C. to obtain TMBQ, and the concentration of TMP is about 5-60% wt.
