A Bio-Based Alginate Aerogel as an Ionic Liquid Support for the Efficient Synthesis of Cyclic Carbonates from CO2 and Epoxides

In this work, the ionic liquid [Aliquat][Cl] was supported into alginate and silica aerogel matrices applied as a catalyst in cycloaddition reaction between CO2 bio-based epoxide (limonene oxide). The efficiency of system is much higher than that one. method wet impregnation used for with zinc complex. procedure originated well-defined thin solvent film on surface support materials. Final materials were characterised by Fourier Transform Infrared Spectroscopy, N2 Adsorption–Desorption Analysis, X-ray diffraction, atomic absorption Field Emission Scanning Microscopy. Several catalytic tests performed high-pressure apparatus at 353.2 K 4 MPa CO2.
