▎ 摘  要

NOVELTY - Continuous preparation of hydrogenated bisphenol A, involves adding bisphenol A and a graphene-loaded ruthenium catalyst having a size of 600-1000 mesh, to a solvent under stirring conditions to obtain a glue solution, feeding hydrogen and the glue solution to a microchannel reactor, preferably a silicon carbide microchannel reactor, in a continuous manner, and hydrogenating. USE - Continuous preparation of hydrogenated bisphenol A. ADVANTAGE - The method enables simple, safe and continuous preparation of hydrogenated bisphenol A having a cis/trans isomer ratio of up to 65%, with a conversion rate of 100% under mild reaction conditions in short reaction time.
