Synthesis of butyl cinnamate using enzymatic membrane reactor in a free solvent system

Abstract Cinnamic acid is a phenolic compound that has the potential to act as natural antioxidant. esterification can be performed by adding alcohol an alkyl group donor. This carried out increase antioxidant capacity of cinnamic acid. Esterification with butanol donor was best condition modify In this study, synthesis butyl cinnamate using enzymatic membrane reactor (EMR) continuously Lipozyme TL IM catalyst. study aimed determine optimal conditions for various concentrations acid, biocatalyst, residence time, and presence molecular sieves. The at 40°C optimum when sieves were present 0.01 M concentration, 1% (w/v) 12 h time.
