Synthesis of Octyl Dihydrocaffeate and Its Transesterification with Tricaprylin Catalyzed by Candida antarctica Lipase
This work aimed at producing a phenolic ester from dihydrocaffeic acid (DHCA), besides carrying out transesterification reactions of this ester with tricaprylin. The esterification reaction was performed in two ratios (1:1 and 1:3 DHCA:octanol), and the transesterification was done in four ratios (1...
