Abstract
Continuous enzymatic synthesis of butyl butyrate has studied in a packed bed reactor (PBR) using Novozym 435 (Candida antarctica lipase B immobilized on macroporous polyacrylate resin). Esterification reaction of butyric acid and butanol was quickly occurred without any by-product in organic solvents. Several solvents such as heptane, hexane, 1,4 dioxane and tetrahydrofuran were screened for the esterification and hexane showed the highest conversion. The effect of various parameters, such as temperature, molar ratio of butyric acid to butanol, batch reactor on the conversion was inspected. The maximum conversion of butyl butyrate was obtained at 50 ℃, 1 or less of molar ratio of butyric acid to butanol. For continuous butyl butyrate production, the PBR system was suitable model to scale up of process.
