Abstract
Butyl butyrate was continuously synthesized by immobilized lipase Novozym 435 in a packed bed reactor (PBR). Esterification reaction of butyric acid and butanol was quickly occurred without any by-product in organic solvents. Several solvent candidates were investigated to select the suitable solvent for the butyl butyrate production, and hexane showed the highest efficiency. 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.
