Synthesis of Isopropyl Ferulate Using Silica-Immobilized Lipase in an Organic Medium
Figure 7
Repetitive use of immobilized biocatalyst for the synthesis of isopropyl ferulate. The esterification was performed for 3 h at 45°C using isopropanol (100 mM) and ferulic acid (25 mM) in DMSO under shaking. A significant decline in the yield of isopropyl ferulate was recorded after each cycle of repetitive esterification after the 1st cycle of repetitive esterification in the presence of molecular sieves (100 mg/mL; ).
