A Sustainable-by-Design Process for the Selective Photooxidation of Ethylbenzene in a Scalable Agitated Baffle Reactor

This study presents a sustainable-by-design approach for the selective photooxidation of ethylbenzene under continuous flow conditions using sodium anthraquinone-2-sulfonate (SAS) as a water-soluble photocatalyst. The reaction was conducted in a scalable agitated baffle reactor (SABRe) under ultraviolet (UV)-A irradiation (365 nm), enabling enhanced mixing, illumination, and gas−liquid contact.
