| Abstract: | Sucrose-laurate was synthesized by using immobilized lipase as the biocatalyst in solvent-free system. Several factors,such as molar ratio of substrates,pH,initial water activity and salt hydrate pairs have been investigated initially in the esterificated reaction, and reaction selectivity was also analyzed. |
