  • Patent number: 6500972
    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.
    Type: Grant
    Filed: July 25, 2001
    Date of Patent: December 31, 2002
    Assignee: Chinese Petroleim Corp.

  • Patent number: 6180836
    Abstract: The invention relates to a novel one-step process for preparation of phenol by oxidation of benzene with hydrogen peroxide catalyzed by molecular sieves doped with copper ions. With proper solvent, a phenol yield around 15-35%, selectivity close to 100% and phenol/Cu TON around 100 could be achieved. These results show that the inventive process is of great economical value for further development in large scale production of phenol.
