Glycidyl butyrate was synthesized from racemic epichlorohydrin and butyric acid by chemical means. The purity of the refined product was over 96% and the yield was about 47%.
The optimal enzyme resource, porcine pancreatic lipase(PPL), was confirmed by proper test in the resolution of racemic glycidol via esterification with a fatty acid in organic media.
