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&deg; C. to obtain TMBQ, and the concentration of TMP is about 5-60% wt.

Synthesis of TMBQ with transition metal-containing molecular sieve as catalysts

The present invention provides methods for preparing hydrothermally stable MCM-41 mesoporous molecular sieves incorporating aluminum and other transition metals. The materials prepared by these methods possess a very high surface area and narrow uniform pore distribution in the mesopore region, and are highly thermally stable whereby the ions are not leached out after high temperature annealing.
