  • Diels-alder reactions catalyzed by lewis acid containing solids: renewable production of bio-plastics
    Patent number: 9108982
    Abstract: The present disclosure is related to silica-based Lewis acid catalysts, being essentially devoid of strong Brønsted acid character, and their ability to effect the [4+2] cycloaddition and dehydrative aromatization of dienes and dienophiles containing oxygenated substituents to form substituted benzene products. In some embodiments, the processes comprise contacting biomass-derived substrates with ethylene to form terephthalic acid and its derivatives.
    Type: Grant
    Filed: December 5, 2014
    Date of Patent: August 18, 2015
    Assignee: California Institute of Technology
    Inventors: Mark E. Davis, Joshua J. Pacheco
