Abstract:
The combination of continuous flow technology with immobilizing of only 0.13 mol% of triflic acid (TfOH) on silica-encapsulated superparamagnetic iron oxide nanoparticles (SPIONs) under solvent-free conditions successfully provided a powerful, efficient, and eco-friendly route for the synthesis of plasticizers. The turnover frequency value in micro-flow conditions varied in the range of 948.7 to 7384.6 h⁻¹ compared to 403.8 to 3099 h⁻¹ for in-flask. This technique works efficiently, encouraging future applications of micro-flow nano-catalysis in green chemistry.
