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.
本公开涉及基于硅的路易斯酸催化剂,基本上不具有强布朗斯特酸特性,以及它们在作用[4+2]环加成和脱水芳构化二烯和二烯酰基含氧取代基的产物形成取代苯方面的能力。在某些实施例中,这些过程包括将生物质衍生底物与乙烯接触,形成对苯二甲酸及其衍生物。
