This study investigates the potential application of the (Ammonio)butane-1-sulfonate modified Spirulina (Arthrospira) platensis biomasses in the synthesis of 3-aryl-2-oxazolidinones from CO2, ethylene oxide, and anilines. High catalytic activity and ease of recovery from the reaction mixture using filtration and several reuse times without significant losses in performance are additional eco-friendly attributes of this catalytic system. The effects of the structure of ionic liquid on the catalytic performance were investigated and the various reaction conditions were optimized. This observation was exploited in the direct and selective chemical fixation of CO2, affording high degrees of CO2 capture and conversion.
