Abstract:Durene is a valuable aromatic hydrocarbon used in making polyimide and aviation kerosene additives, which traditionally rely on unsustainable petroleum sources, leading to high costs and environmental concerns. Herein, we introduce an alternative method for synthesizing durene with high selectivity through trimethylbenzene methylation coupled with CO 2 hydrogenation. Durene selectivity of 83.2% in tetramethylbenzene (TetraMB) and TetraMB selectivity of 69.1% in aromatics were achieved with a 1,2,4-trimethylben… Show more
