Abstract :
[en] Waste management is a central advantage of heterogeneous catalysis, as it enables catalyst recovery, reuse and a significant reduction in hazardous byproducts, thereby improving environmental sustainability [1]. In this context, the catalytic chlorination reaction provides an efficient route to synthesize natural allylic chloride derivatives [2], which are important intermediates that serve as building blocks for more complex atomic arrangements [3], supporting cleaner and more sustainable chemical processes.
The present work focuses primarily on the advanced characterization of an iron-rich industrial mining waste by XRD, XRF, FTIR, Raman, 57Fe Mössbauer spectroscopy, SEM-EDX, BET and Zeta-seizer analyses. Thereafter, we have investigated for the first time its application as an efficient magnetically recoverable heterogeneous catalyst in the selective catalytic chlorination of terpenic olefins.
The studied waste material presents a novel alternative to unlock the heterogenization of the chlorination reaction, aligning with waste recycling strategy. This highlights the novelty of applying waste-to-resource approach by reusing an iron-rich industrial mining waste as high magnetically recoverable heterogeneous catalyst for a better circular economy and sustainable chemistry.
