A sustainable chemoenzymatic process to make glycerine carbonate acrylate (GCA) and glycerine carbonate methacrylate (GCMA) as useful monomers for making biodegradable plastics was carried out using ionic liquid (ILs) technologies. The process consisted of two sequential catalytic steps, which can be carried out by either sequential or one-pot experiments. The glycidyl (meth) acrylate was first synthesized by enzymatic transesterification from (meth) acrylate vinyl ester with glycidol in spongy ionic liquids (SLILs) as the reaction medium (100% yield after 6 h at 60 ° C.). SLILs not only provided a suitable reaction medium, but also enabled the simple isolation of the resulting glycidyl esters as an IL-free pure fraction by a simple cooling / centrifugation protocol. The second step consisted of the GCA or GCMA synthesis as a result of the cycloaddition of CO2 to the glycidyl acrylate or glycidyl methacrylate obtained, catalyzed by a covalently bound 1-decyl-2-methylimidazolium unit (Supported Ionic Liquids-Like) phase, SILLP ) in a solvent-free system and under mild conditions (60 ° C, 1-10 bar), which leads to a yield of up to 100% after 6 hours. The components of the reaction system (biocatalyst / SLIL / SILLP) can be fully recovered and reused for at least 6 cycles with unchanged catalytic performance.
