Abstract: The present disclosure provides methods to produce para-xylene, toluene, and other compounds from renewable sources (e.g., cellulose, hemicellulose) and ethylene in the presence of an acid, such as a Lewis acid. For example, cellulose and/or hemicellulose may be converted into 2,5-dimethylfuran (DMF) and 2-methylfuran, which may be converted into para-xylene and toluene, respectively. In particular, para-xylene can then be oxidized to form terephthalic acid.

Abstract: Provided herein are methods that utilize polyhydroxyalkanoates (PHAs) as a substrate for further conversion to C4 and C5 compounds. Polyhydroxyalkanoates can undergo esterification to yield alkyl hydroxyalkanoates and alkyl alkenoates, which may serve as useful precursors in the production of alkadienes and alkenedioic acids, including for example butadiene and butenedioic acid.
