Abstract:
We propose an alternative of a biocatalytic conversion of glycerol (bio-glycerol) to glycerol carbonate (GlyC) as a value-added product with numerous applications in cosmetics, pharmaceutics, detergents and adhesives industry. The biocatalytic process involved glycerol carbonylation with dimethyl carbonate (DMC) assisted by a lipase biocatalyst. The corresponding system was set up for solvent-free conditions using an excess of DMC with different designs of the biocatalyst (e.g. homogeneous and heterogeneous biocatalyst). The system performance was evaluated separately considering each biocatalyst. The performances of the developed biocatalytic system were investigated for bio-glycerol collected directly from the biodiesel process taking under consideration different feedstock patterns (e.g. soybean, sunflower, rapeseed, corn, olive, palm, and residual oil) and the effects of the corresponding matrices on the bio-synthesis of GlyC.
