In the present work, enzymatic/mild acidolysis lignin (EMAL) was isolated from the raw material Cunninghamia lanceolata, and hydrothermal depolymerization was carried out in subcritical water (from 250 to 350 °C) using a cylindrical autoclave. The results revealed that the lowest yield of solid residue and highest liquid product yield were achieved at 325 °C. The liquid products were primarily ...

Abstract Response surface methodology (RSM) was used to optimize the degree of esterification p -coumaric acid triolein via lipase-catalyzed acidolysis, and enzyme load, reaction time mole ratio substrates were selected as variables in experimental design. The results showed that model employed highly sufficient for determining effectiveness interaction three variables, substrates, on dependent...
