Compared to the batch reaction with only 60% conversion of n-butanol, the reactive distillation column can improve the conversion ofn- butanol (up to 93.6%) and the lipase-loaded packing storage in the reaction system at 70 C for 120 days verified that the conversions could still reach 72.5%. Experimental work pertaining to alcoholysis between butanol and ethyl butanoate, catalyzed by an immobilized lipase in a liquidvapor system where chemical reaction and physical separation are simultaneously carried out, finds the integrated configuration tested is quite effective toward improvement of the final yield of the desired product.
